SAFETY  
Battery posts, terminals and related accessories contain lead and lead compounds,  
chemicals known to the state of California to cause cancer, birth defects or other  
reproductive harm. (SG-31)  
Operator Safety Instructions and Practices  
Never operate the Tractor or Implement until you have read and  
completely understand this Manual, the Tractor Operator’s Manual, and  
each of the Safety Messages found in the Manual or on the Tractor and  
Implement. Learn how to stop the tractor engine suddenly in an  
emergency.  
Never allow inexperienced or untrained personnel to  
operate the Tractor and Implement without supervision. Make sure the  
operator has fully read and understood the manuals prior to operation.  
(SG-4)  
The operator and all support personnel should wear hard hats, safety  
shoes, safety glasses, and proper hearing protection at all times for  
protection from injury including injury from items that may be thrown by  
the equipment. (SG-16)  
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE  
PERMANENT HEARING LOSS! Tractors with or without an Implement  
attached can often be noisy enough to cause permanent hearing loss.  
We recommend that you always wear hearing protection if the noise in  
the Operator’s position exceeds 80db. Noise over 85db over an  
extended period of time will cause severe hearing loss. Noise over 90db  
adjacent to the Operator over an extended period of time will cause  
permanent or total hearing loss. NOTE: Hearing loss from loud noise  
[from tractors, chain saws, radios, and other such sources close to the  
ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)  
Always read carefully and comply fully with the manufacturer’s  
instructions when handling oil, solvents, cleansers, and any other  
chemical agent. (SG-22)  
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement  
and possible serious injury or death. (SG-24)

SAFETY  
Equipment Operation Safety Instructions and Practices  
Never leave the Tractor and Implement unattended while the Implement is in the lifted posi-  
tion. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of  
unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor,  
lower the stand and put the retaining pin securely in place, or put a secure support under the A-Frame. Lower  
the implement carefully to the ground. Do not put hands or feet under lifted components. (S3PT-1)  
This Implement is wider than the Tractor. Be careful when operating or transporting this  
equipment to prevent the Implement from running into or striking sign posts, guard rails,  
concrete abutments or other solid objects. Such an impact could cause the Implement and  
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.  
Never allow the Implement to contact obstacles. (S3PT-12)  
Use extreme caution when raising the Mower head. Stop the Blades from turning when the  
Mower Head is raised and passersby are within 100 yards. Raising the Mower head  
exposes the Cutting Blades which creates a potentially serious hazard and can cause  
serious injury by objects thrown from the Blades or by contact with the Blades. (SBM-2)  
Never Leave the mower unattended while the head is in the raised  
position. The mower could fall causing serious injury to anyone who  
might inadvertently be under the mower. (SBM-4)  
Always keep a careful lookout and use extreme care when working  
around overhead obstructions. Never allow the Mower head or boom  
within 10 feet of any power line. When working close to overhead  
power lines consult your electric company for a safe code of operation.  
(SBM-7)  
The center of Gravity of Tractors equipped with a Rear-Mounted Boom  
Mower is shifted to the rear and removes weight from the front wheels.  
Add front ballast until at least 20% of the tractors weight is on the front  
wheels to prevent rearing up, loss of steering control, and possibly  
injury. (SBM-10)  
The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.  
(SBM-15)  
Use extreme care and Safety Awareness when using the boom mower head to mulch loose  
brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this  
debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This  
cut debris can be thrown at great velocities and could result in serious injury or even death. (SBM-17)  
Do not back up this implement when the boom or mower head is extended. Backing could  
damage the machine or its components. (SBM-19)

SAFETY  
Follow these guidelines to reduce the risk of equipment and  
grass fires while operating, servicing, and repairing the Mower  
and Tractor:  
-Equip the Tractor with a fire extinguisher in an accessible  
location.  
-Do Not operate the Mower on a Tractor with an underframe  
exhaust.  
-Do Not smoke or have an open flame near the Mower and  
Tractor.  
-Do Not drive into burning debris or freshly burnt areas.  
-Do Not attempt to mow or place the mower head close to  
burning debris.  
-Never allow clippings or debris to collect near drivelines,  
gearboxes or hydrualic componts such as valves, tanks,  
pumps and motors. Periodically shut down the Tractor and  
Mower and clean clippings and collected debris from the  
mower deck. (SBM-20)  
Do not operate Mower if excessive vibration exists.  
Shut down PTO and the Tractor  
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are  
missing or damaged replace them immediately.  
Do not operate the mower until the  
blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration  
can result in component failure and broken objects to be thrown outward at very high velocities. To reduce the  
possibility of property damage, serious injury, or even death, never allow the Mower to be operated with  
blades missing. (SFL-4)

SAFETY  
Flail Mowers are capable under adverse conditions of throwingobjects  
for great distances (100 yards or more) and causing seriousinjury or  
death. Follow safety messages carefully.  
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:  
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,  
workablecondition;  
-Mower sections  
or Wings are running close to and parallel to the ground  
withoutexposed Blades;  
-Passerby are outside the existing thrown-object zone;-All areas have been thoroughly  
inspected and all foreign material such as rocks, cans, glass, and general debris has  
been removed.  
NOTE: Where there are grass and weeds high enough to hide debris that could  
bestruck by the blades, the area should be: inspected and large debris removed, mowed  
atan intermediate height, inspected, closely with any remaining debris being removed,  
andmowed again at desired final height. (This will also reduce power required to  
mow,reduce wear and tear on the Mower drivetrain, spread cut material better,  
eliminatestreaking, and make the final cut more uniform.) (SFL-6)  
Operate this Equipment only with a Tractor equipped with an approved roll-  
over-protective system (ROPS). Always wear seat belts. Serious injury or  
even death could result from falling off the tractor--particularly during a turnover  
when the operator could be pinned under the ROPS. (SG-7)  
BEFORE leaving the tractor seat, always engage the brake and/or set  
the tractor transmission in parking gear, disengage the PTO, stop the  
engine, remove the key, and wait for all moving parts to stop. Place the  
tractor shift lever into a low range or parking gear to prevent the tractor  
from rolling. Never dismount a Tractor that is moving or while the engine  
is running. Operate the Tractor controls from the tractor seat only. (SG-9)  
Never allow children or other persons to ride on the Tractor or Implement.  
Falling off can result in serious injury or death. (SG-10)  
Never allow children to operate, ride on, or come close to the Tractor or  
Implement. Usually, 16-17 year-old children who are mature and  
responsible can operate the implement with adult supervision, if they  
have read and understand the Operator’s Manuals, been trained in  
proper operation of the tractor and Implement, and are physically large  
enough to reach and operate the controls easily. (SG-11)

SAFETY  
Do not mount the Tractor while the tractor is moving. Mount the Tractor  
only when the Tractor and all moving parts are completely stopped. (SG-12)  
Start tractor only when properly seated in the Tractor seat. Starting a  
tractor in gear can result in injury or death. Read the Tractor operators  
manual for proper starting instructions. (SG-13)  
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and  
fuel are explosive and their presence could present a hazard. Do not  
check for leaks with your hand! High-pressure oil streams from breaks in  
the line could penetrate the skin and cause tissue damage including  
gangrene. To check for a hose leak, SHUT the unit ENGINE OFF and  
remove all hydraulic pressure. Wear oil impenetrable gloves, safety  
glasses and use Cardboard to check for evidence of oil leaks. If you  
suspect a leak, REMOVE the HOSE and have it tested at a Dealer. If oil  
does penetrate the skin, have the injury treated immediately by a  
physician knowledgeable and skilled in this procedure. (SG-15)  
Never run the Tractor engine in a closed building or without adequate ventilation. The  
exhaust fumes can be hazardous to your health. (SG-23)  
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause  
Implement driveline or blade failures resulting in serious injury or death. (SG-26)  
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat  
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or  
Implement may cause serious injury or death. (SG-29)  
In case of mechanical difficulty during operation, place the transmission in the park  
position, set the parking brake, shut down all power, including the PTO and the engine and  
remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39)

SAFETY  
Do Not operate this equipment in areas where insects such as bees may attack you and/or  
cause you to lose control of the equipment. If you must enter in such areas, use a tractor  
with an enclosed Cab and close the windows to prevent insects from entering. If a tractor  
cab is not available, wear suitable clothing including head, face, and hand protection to  
shield you from the insects. Attacking insects can cause you to lose control of the tractor,  
which can result in serious injury or death to you or bystanders. Never dismount a moving  
tractor. (SG-40)  
Mow only in conditions where you have clear visibility in daylight or with adequate artificial  
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least  
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can  
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,  
power lines, debris and foreign objects. If you are unable to clearly see these type of items  
discontinue mowing. (SGM-1)  
There are obvious and hidden potential hazards in the operation of this  
Mower. REMEMBER! This machine is often operated in heavy brush  
and in heavy weeds. The Blades of this Mower can throw objects if  
shields are not properly installed and maintained. Serious injury or even death may occur  
unless care is taken to insure the safety of the operator, bystanders, or passersby in the  
area. Do not operate this machine with anyone in the immediate area. Stop mowing if  
anyone is within 100 yards of mower. (SGM-2)  
The rotating parts of this machine have been designed and tested for rugged use.  
However, the blades could fail upon impact with heavy, solid objects such as metal guard  
rails and concrete structures. Such impact could cause the broken objects to be thrown  
outward at very high velocities. To reduce the possibility of property damage, serious  
injury, or even death, never allow the cutting blades to contact such obstacles. (SGM-4)  
Extreme care should be taken when operating near loose objects such  
as gravel, rocks, wire, and other debris. Inspect the area before  
mowing. Foreign objects should be removed from the site to prevent  
machine damage and/or bodily injury or even death. Any objects that cannot be removed  
must be clearly marked and carefully avoided by the operator. Stop mowing immediately if  
blades strike a foreign object. Repair all damage and make certain rotor or blade carrier is  
balanced before resuming mowing. (SGM-5)  
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the  
operating parts of the mower head. These items could then swing outside the housing at  
greater velocities than the blades. Such a situation is extremely hazardous and could result  
in serious injury or even death. Inspect the cutting area for such objects before mowing. Remove any like  
object from the site. Never allow the cutting blades to contact such items. (SGM-6)

SAFETY  
Mow at the speed that you can safely operate and control the tractor and mower. The  
correct mowing speed depends on terrain condition and grass type, density, and height of  
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds  
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when  
debris and foreign objects are to be avoided. (SGM-7)  
Avoid mowing in reverse direction when possible. Check to make sure there are no  
persons behind the mower and use extreme care when mowing in reverse. Mow only at a  
slow ground speed where you can safely operate and control the tractor and mower.  
Never mow an area that you have not inspected and removed debris or foreign material.  
(SGM-8)  
Do not mow with two machines in the same area except with Cab tractors with the windows  
closed. (SGM-11)  
Follow these guidelines to reduce the risk of equipment and grass fires  
while operating, servicing, and repairing the Mower and Tractor:  
-Equip the Tractor with a fire extinguisher in an accesible location.  
-Do Not operate the Mower on a Tractor with an underframe exhaust.  
-Do Not smoke or have an open flame near the Mower and Tractor.  
-Do Not drive into burning debris or freshly burnt areas.  
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.  
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.  
Periodically shut down the Tractor and Mower and clean clippings and collected debris from  
the mower deck. (SGM-12)  
The Mower is designed for certain mowing applications and is rated to cut up to a specific  
size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this  
mower to cut vegetation above the Mower’s rated capacity or to cut any type of non-  
vegetative material. Only operate this Mower on a properly sized and equipped Tractor. Operating this Mower  
in an application for which it is not designed and/or operating the Mower with the wrong size Tractor can cause  
Mower component damage and equipment failure resulting in possible serious injury or death. (SGM-14)  
Never leave the Implement and Power Unit unattended while the Implement is in the raised  
position. Accidental operation of a lifting lever or a hydraulic failure may cause the  
implement to suddenly fall causing serious injury or possible death to anyone who might  
inadvertently be under the Implement. Lower the implement carefully to the ground. Do not  
put hands or feet under lifted components. (SPU-3)

Transporting Safety Instructions and Practices  
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go  
up hills only at a low speed and using a gradual steering angle. Rear mounted implements  
move the center of gravity to the rear and remove weight from the front wheels. Make  
certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing  
up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent loss of  
steering control which could result in property damage or possible injury. Do not transport unless 3-Point lift  
lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious  
damage to the tractor and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)  
Allow sufficient clearance for the Implement to swing outward while turning. Implements  
carried behind the Tractor will swing outside the tire path when making turns. Contacting a  
solid object while turning will cause equipment damage and possible injury. (S3PT-20)

SAFETY  
Be particularly careful in transport. The Mower has raised the center of  
gravity for the tractor and has increased the possibility of overturn.  
Turn curves or go up slopes only at low speed and using a gradual  
turning angle. Slow down on rough or uneven surfaces. (SBM-3)  
When transporting Boom Mower on a truck or trailer, the height or width  
may exceed legal limits when the boom is in the transport position.  
Contact with side or overhead structures or power lines can cause  
property damage or serious injury or death. If necessary lower boom to  
reduce height and/or remove mowing head to reduce width to the legal  
limits. (SBM-8)  
Never operate the Tractor and Mower Unit without an OPS (Operators  
Protective Structure) or Cab to prevent injury from objects thrown from  
ground or from overhead trimming.  
passersby are with in 100 yards. (SBM-9)  
Stop mowing if workers or  
The Joystick Master Control Switch must be OFF to prevent accidental movement of the  
boom and cutting head whenever the mower is not being operated. (SBM-16)  
Secure the boom and mower head in the transport position before traveling on public roads.  
Never transport on public roads with the boom and mower head extended. Always  
disengage and lock out the hydraulic controls for the boom mower before transporting.  
Inadvertent boom movement on public roads may contact with other vehicles resulting in  
serious bodily injuries or even death. (SBM-21)  
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in  
such a way as to be clearly visible and legible. When transporting the  
Equipment use the Tractor flashing warning lights and follow all local  
traffic regulations. (SG-6)

SAFETY  
Transport only at speeds where you can maintain control of the  
equipment. Serious accidents and injuries can result from operating this  
equipment at high speeds. Understand the Tractor and Implement and how it handles  
before transporting on streets and highways. Make sure the Tractor steering and brakes  
are in good condition and operate properly.  
Before transporting the Tractor and Implement, determine the proper transport speeds for  
you and the equipment. Make sure you abide by the following rules:  
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly  
to determine the stopping characteristics of the Tractor and Implement. As you increase  
the speed of the Tractor the stopping distance increases.  
Determine the maximum  
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.  
Test the equipment at a slow speed in turns. Increase the speed through the turn only after  
you determine that the equipment can be operated at a higher speed. Use extreme care  
and reduce your speed when turning sharply to prevent the tractor and implement from  
turning over. Determine the maximum turning speed for you and this equipment before  
operating on roads or uneven ground.  
Only transport the Tractor and Implement at the speeds which allow you to properly control  
the equipment.  
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes  
or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance  
increases: use extreme care and reduce your speed. When operating in traffic always use  
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you  
and watch out for the other guy. (SG-19)  
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before  
driving on public roadways identify any limited vision areas, and make adjustments to your  
operating position, mirrors, and the implement transport position so that you can clearly  
see the area where you will be traveling, and any traffic that may approach you. Failure to  
maintain adequate vision of the public roadway and traffic can result in serious injury or  
even death. (STI-10)  
Concluding Safety Instructions and Practices  
In addition to the design and configuration of this Implement, including Safety Signs and Safety Equipment,  
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper  
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer  
also to Safety Messages and operation instruction in each of the appropriate sections of the Tractor and  
Equipment Manuals. Pay close attention to the Safety Signs affixed to the Tractor and Equipment. (SG-18)

OPERATION  
2.TRACTOR REQUIREMENTS  
In addition to tractor horsepower and size required to operate the boom unit, the tractor must also be properly  
equipped to provide operator protection, to alert approaching vehicle drivers of the tractor’s presence, and to  
ensure tractor stability when mowing with the boom fully extended.  
Tractor Requirements and Capabilities  
ASAE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.  
Operator Protection..........................Tractor must be equipped with protective structure such as operator  
cage or lexan window to protect operator from thrown object and falling objects  
Tractor Safety Devices ....................Slow Moving Vehicle (SMV) emblem, lighting,  
Tractor Ballast .................................As required to maintain at least 1500 lbs. on left rear tire  
2.1 ROPS and Seat Belt  
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat  
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be  
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.  
Tractor model not equipped with a ROPS and seat belt should have these life saving features installed by an  
authorized dealer. OPS-U- 0003  
Operate this Equipment only with a Tractor equipped with an approved roll-  
over-protective system (ROPS). Always wear seat belts. Serious injury or  
even death could result from falling off the tractor--particularly during a turnover  
when the operator could be pinned under the ROPS. (SG-7)  
2.2 Operator Thrown Object Protection

OPERATION  
2.4 Tractor Ballast  
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum  
down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended  
and the mower head is horizontal and two feet above the ground. For units which have the ability to operate  
on either side of the tractor, these requirements must also be met for the right side tire when the boom is  
extended to the left side as described above. A tractor that does not meet this criteria is DANGEROUS and  
should not be operated as upset of the unit can occur resulting in possible serious injury and property  
damage. NOTE: All factory mounted units are tested and meet the ballast requirement before shipment;  
further testing is not required unless the unit is operated in a manner other than what is considered standard  
operating conditions.  
For additional information on properly ballasting the tractor, refer to Alamo Industrial Tractor and Mower  
Stability Pamphlet P/N #02959010  
If the unit is operated on slopes greater than 5°,  
additional counterweight will be required.  
Operation of the unit on slopes greater than 11  
percent (6.4 degrees) is not recommended under  
any circumstances. On a tractor with a 96” outside  
to outside tire spread, an 11 percent (6.4 degrees)  
slope occurs when one rear tractor tire is about 8”  
lower than the other rear tire. OPS-B- 0018  
3.GETTING ON AND OFF THE TRACTOR  
Before getting onto the tractor, the operator must read and completely understand the implement and tractor  
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for  
a complete explanation. OPS-U- 0007  
Do not mount the Tractor while the tractor is moving. Mount the Tractor  
only when the Tractor and all moving parts are completely stopped. (SG-12)

3.1 Boarding the Tractor  
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control  
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt  
around you.  
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be  
seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra  
riders at all times. OPS-U- 0008  
Never allow children to operate, ride on, or come close to the Tractor or  
Implement. Usually, 16-17 year-old children who are mature and  
responsible can operate the implement with adult supervision, if they  
have read and understand the Operator’s Manuals, been trained in  
proper operation of the tractor and Implement, and are physically large  
enough to reach and operate the controls easily. (SG-11)  
Never allow children or other persons to ride on the Tractor or Implement.  
Falling off can result in serious injury or death. (SG-10)  
Do not mount the Tractor while the tractor is moving. Mount the Tractor  
only when the Tractor and all moving parts are completely stopped. (SG-12)  
3.2 Dismounting the Tractor  
Before dismounting the tractor, idle the tractor engine down, disengage the head and retract the boom arm to  
the transport position. Park the tractor on a level surface, set the transmission in park or neutral and apply  
the parking brake. Shut down the tractor engine, remove the key, and wait for all motion to come to a  
complete stop before exiting the operator’s seat. NEVER leave the seat until the tractor, its engine, and  
mower head movement have come to a complete stop.  
Use hand rails and extra steps when exiting the tractor. Be careful of your step and use extra caution when  
mud, ice, snow, and other matter has accumulated on the steps and handrails. Never rush or jump off the  
tractor. OPS-B- 0002  
BEFORE leaving the tractor seat, always engage the brake and/or set  
the tractor transmission in parking gear, disengage the PTO, stop the  
engine, remove the key, and wait for all moving parts to stop. Place the  
tractor shift lever into a low range or parking gear to prevent the tractor  
from rolling. Never dismount a Tractor that is moving or while the engine  
is running. Operate the Tractor controls from the tractor seat only. (SG-9)

specific type oil if low)  
Change hydraulic oil filter and hydraulic oil  
according to maintenance schedule.  
Ensure there are no oil leaks and fitting are  
properly connected  
Inspect overall condition of hydraulic pump.  
Inspect pump drive shaft.  
Check the fluid level in the Hydraulic Tank on the  
Tractor, and add oil if required. As the air has been forced out of the Cylinders and Hoses, it goes into the  
Hydraulic Tank and reduces the volume of oil. Maintain the oil level within the sight gauge located on the side  
of the resevoir. Never fill the tank above the sight gauge to allow for the expansion of the oil. The tank  
maintains pressure after the mower has been run. Stand off to one side when removing the breather cap  
element to prevent possible injury. To relieve pressure remove the breather cap element and depress the  
spring loaded pressure valve to release any excess air. OPS-B- 0024_A  
Attention: Oil Filler Cap is also the Pressure Relief Cap.  
Remove cap slowly to relieve pressure before removing cap completely. Stay clear to pre-  
vent being scalded with hot oil that may spray out of the tank that is still pressurized and may  
cause serious injury to eyes, face, and exposed skin. (Ops-0001-MISC)  
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and  
hose connections. Relieve hydraulic pressure before performing maintenance or repairs.  
Use gloves and eye protection when servicing hot components. Contact with a hot surface  
or fluid can cause serious injury from burns or scalding. (SG-34)

OPERATION  
7.OPERATING THE BOOM JOYSTICK CONTROL  
Positioning the boom is performed with electronic valves controlled by the operator using a single joystick.  
The joystick controls five standard operations: Swing, Lift, Dipper, Head, Tilt, and Door. Of these five  
operations, the Swing, Lift, and Dipper functions are proportional; that is, when the joystick is moved a small  
amount, the cylinder moves slowly and as the joystick continues to be moved, the cylinder continually  
becomes faster. This allows very precise positioning of the boom. Using a single joystick, many of the  
functions can be operated simultaneously such as the Lift and Dipper for even greater speed at positioning of  
the boom.  
For safe and efficient boom mower operation, it is critical that the operator be experienced and feel confident  
in using the joystick control to position the boom. New operator’s should allowed ample time to practice using  
the joystick in an open area before entering the worksite. Before attempting to operate this equipment, read  
these instructions completely. If you have any questions concerning safety of operation, contact your dealer  
or ALAMO INDUSTRIAL.  
Each joystick control and responding boom action is covered in detail on the following pages. Read each  
explanation carefully then practice in a safe, level area, CLEAR of all people, animals, and any obstructions.  
As always, use extreme caution when using this machine.  
Practice performing multiple functions simultaneously. With some practice, the joystick will become very easy  
to operate and will feel almost as it were an extension of your arm.  
With the exception of the relief valves, which are preset at the factory, these are all the controls for operating  
the machine other than the controls on the tractor itself.  
Master Switch  
Operating any joystick function requires that the joystick Master Switch be ON. When  
ON the master switch indicator light will be illuminated. Turning off the master switch will  
deactivate all joystick controls. The master switch also serves as a safety device and  
will prevent the tractor from being started if the master switch is in the ON position.  
OPS-B- 0030_A  
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat  
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or  
Implement may cause serious injury or death. (SG-29)

OPERATION  
8.DRIVING THE TRACTOR AND IMPLEMENT  
Safe tractor transport requires the operator to possess a thorough knowledge of the model being operated  
and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to  
handle the weight of the boom and the tractor operating controls are set for safe transport. To ensure safety  
while driving the tractor with a boom, review the following.  
Read all safety instructions. Decals on the Boom warn you of particular and multiple hazards. Some decals  
are attached close to part of the Boom where there is a possible hazard. Read and make sure you  
understand the safety messages before you operate the implement. Keep all decals clean and readable.  
Replace lost or damaged decals, refer to safety section for more information.  
Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for  
engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating  
speed of 540 PTO RPM. Always engage the PTO at low engine RPM and run the mower for a short period  
until all air is removed from the hoses. Keep all person's well clear of mower since blades can throw objects  
with great velocity for a considerable distance! KEEP CLEAR! OPS-B- 0005  
Never operate the Tractor or Implement until you have read and  
completely understand this Manual, the Tractor Operator’s Manual, and  
each of the Safety Messages found in the Manual or on the Tractor and  
Implement. Learn how to stop the tractor engine suddenly in an  
emergency.  
Never allow inexperienced or untrained personnel to  
operate the Tractor and Implement without supervision. Make sure the  
operator has fully read and understood the manuals prior to operation.  
(SG-4)  
Always maintain the safety signs in good readable condition. If the safety signs are missing,  
damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5)  
BEFORE leaving the tractor seat, always engage the brake and/or set  
the tractor transmission in parking gear, disengage the PTO, stop the  
engine, remove the key, and wait for all moving parts to stop. Place the  
tractor shift lever into a low range or parking gear to prevent the tractor  
from rolling. Never dismount a Tractor that is moving or while the engine  
is running. Operate the Tractor controls from the tractor seat only. (SG-9)

OPERATION  
Transport only at speeds where you can maintain control of the  
equipment. Serious accidents and injuries can result from operating this  
equipment at high speeds. Understand the Tractor and Implement and  
how it handles before transporting on streets and highways. Make sure the Tractor steering  
and brakes are in good condition and operate properly.  
Before transporting the Tractor and Implement, determine the proper transport speeds for  
you and the equipment. Make sure you abide by the following rules:  
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly  
to determine the stopping characteristics of the Tractor and Implement. As you increase  
the speed of the Tractor the stopping distance increases.  
Determine the maximum  
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.  
Test the equipment at a slow speed in turns. Increase the speed through the turn only after  
you determine that the equipment can be operated at a higher speed. Use extreme care  
and reduce your speed when turning sharply to prevent the tractor and implement from  
turning over. Determine the maximum turning speed for you and this equipment before  
operating on roads or uneven ground.  
Only transport the Tractor and Implement at the speeds which allow you to properly control  
the equipment.  
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes  
or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance  
increases: use extreme care and reduce your speed. When operating in traffic always use  
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you  
and watch out for the other guy. (SG-19)  
8.1 Starting the Tractor  
The procedure to start the tractor is model specific.  
Refer to the tractor operator’s manual for starting  
procedures for your particular tractor. Consult an  
authorized dealer if the starting procedure is  
unclear. Ensure the 3-point control lever is in the  
lowered position and the PTO is disengaged before  
starting the tractor. OPS-U-0033

OPERATION  
8.2 Brake and Differential Lock Setting  
Make sure the tractor brakes are in good  
operating condition. Tractor brakes can be set to  
operate independently allowing single rear wheel  
braking action or locked together to provide  
simultaneous rear wheel braking. FOR MOST  
DRIVING AND OPERATING CONDITIONS, THE  
BRAKE PEDALS SHOULD BE LOCKED  
TOGETHER TO PROVIDE THE MOST  
EFFECTIVE BRAKING ACTION.  
Always disengage the tractor differential lock  
when turning. When engaged the differential lock  
will prevent or limit the tractor from turning. During  
normal cutting conditions, locking the differential  
provides no benefit and should not be used.  
OPS-U- 0013  
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.  
When operating down a hill or on wet or rain slick roads, the braking distance increases; use  
extreme care and reduce your speed in these conditions. When operating in traffic, always  
use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around  
you and watch out for the other guy.  
BEFORE leaving the tractor seat, always engage the brake and/or set  
the tractor transmission in parking gear, disengage the PTO, stop the  
engine, remove the key, and wait for all moving parts to stop. Place the  
tractor shift lever into a low range or parking gear to prevent the tractor  
from rolling. Never dismount a Tractor that is moving or while the engine  
is running. Operate the Tractor controls from the tractor seat only. (SG-9)

OPERATION  
8.3 Driving the Tractor and Boom  
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the  
tractor. Never operate the tractor at speeds that cannot be safely handled or which will prevent the operator  
from stopping quickly during an emergency. If the power steering or engine ceases operating, stop the tractor  
immediately as the tractor will be difficult to control.  
Perform turns with the tractor and mower at slow  
speeds to determine how the tractor with and  
attached implement handles a turn. Determine the  
safe speed to maintain proper control of the tractor  
when making turns. When turning with the  
implement the overall working length and width of  
the unit is increased. Allow additional clearance for  
the unit when turning or when passing large  
obstructions.  
To avoid overturns, drive the tractor with care and  
at safe speeds, especially when operating over  
rough ground, crossing ditches or slopes, and  
turning corners. Use extreme caution when  
operating on steep slopes. Keep the tractor in a low  
gear when going downhill. DO NOT coast or free-  
wheel downhill.  
OPS-B- 0006_A  
Never Leave the mower unattended while the head is in the raised  
position. The mower could fall causing serious injury to anyone who  
might inadvertently be under the mower. (SBM-4)  
Always keep a careful lookout and use extreme care when working  
around overhead obstructions. Never allow the Mower head or boom  
within 10 feet of any power line. When working close to overhead  
power lines consult your electric company for a safe code of operation.

OPERATION  
9.OPERATING THE BOOM UNIT AND ATTACHED HEAD  
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND  
MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand  
the Safety and Operation Sections of this manual and the tractor operator’s manuals. These manuals must  
be read and explained to any operator who cannot read. Never allow someone to operate the unit without  
complete operating instructions.  
To ensure safety to the operator, bystanders, and equipment and before starting any mowing operation. The  
operator must become familiar with the area to be mowed, and any obstacles and hazards contained within.  
Special attention should be paid to foreign debris, overhead obstrucions, rough terrain, steep  
slopes,passersby and animals in the area.  
Only operate the mower head from the tractor operator’s seat with the seatbelt securely fastened. Only  
®
operate a boom and equipped head on cabbed tractor that is equipped with a Lexan protected right side  
window or a non cabbed tractor equipped with a ROPS and operator safety screen.  
Avoid operating in the reverse direction when possible. In situations where the boom and mower must be  
backed to access areas to be cut, make sure there are no persons or other foreign debris behind the tractor.  
When backing, operate the tractor at a much reduced ground speed to ensure complete control of the unit is  
maintained. OPS-B- 0007  
Do not mow with two machines in the same area except with Cab tractors with the windows  
closed. (SGM-11)  
Mow only in conditions where you have clear visibility in daylight or with adequate artificial  
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least  
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can  
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,  
power lines, debris and foreign objects. If you are unable to clearly see these type of items  
discontinue mowing. (SGM-1)  
Avoid mowing in reverse direction when possible. Check to make sure there are no  
persons behind the mower and use extreme care when mowing in reverse. Mow only at a  
slow ground speed where you can safely operate and control the tractor and mower.  
Never mow an area that you have not inspected and removed debris or foreign material.  
(SGM-8)  
Never operate the mower head tilted down where the operator can see the blades of the  
mower. The blade could throw an object toward the operator causing serious injury or  
death. Never operate the mower without an Operator Protective Structure. Always were  
safety glasses and a hard hat. (Ops-0005-MISC)

OPERATION  
9.1 Foreign Debris Hazards/Overhead Obstructions  
An area to be cut must first be inspected for objects that could be thrown or that could damage the machine.  
Walk through the area looking for fences, boulder, rocks, culverts, stumps or metal objects. Mark the inspected  
area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect a smaller  
area as well as possible, then trim away the part that has been inspected and can safely be removed. Walk  
each new area again and repeat the inspection before cutting more away. Repeat as often as necessary until  
the area is cleared. It can be damaging and/or dangerous to work the cutter in an area that had not been  
visually inspected.  
Place DANGER signs at least 300 feet beyond the perimeter of the area to be worked, not just 300 feet from  
where the machine started operating! It is convenient in many cases to work in 300 foot sections. Move the  
first Danger sign to the beginning of the freshly cleared area, place it, then take the first cutting area flag up to  
the end of the freshly cleared area 300 feet away. Walk and inspect the next 300 feet and place the second  
cutting area flag. Pick up the second DANGER sign, and take it a further 300 feet along the road or trail. Note  
that in many cases the DANGER area will extend in front of and behind the machine as well as along each  
side. Post signs accordingly. OPS-B- 0008  
Extreme care should be taken when operating near loose objects such  
as gravel, rocks, wire, and other debris. Inspect the area before  
mowing. Foreign objects should be removed from the site to prevent  
machine damage and/or bodily injury or even death. Any objects that cannot be removed  
must be clearly marked and carefully avoided by the operator. Stop mowing immediately if  
blades strike a foreign object. Repair all damage and make certain rotor or blade carrier is  
balanced before resuming mowing. (SGM-5)  
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the  
operating parts of the mower head. These items could then swing outside the housing at  
greater velocities than the blades. Such a situation is extremely hazardous and could result  
in serious injury or even death. Inspect the cutting area for such objects before mowing. Remove any like  
object from the site. Never allow the cutting blades to contact such items. (SGM-6)  
Mow at the speed that you can safely operate and control the tractor and mower. The  
correct mowing speed depends on terrain condition and grass type, density, and height of  
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds  
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when  
debris and foreign objects are to be avoided. (SGM-7)

OPERATION  
Rotary Mowers are capable under adverse conditions of throwing objects for great  
distances 100 yards or more) and causing serious injury or death. Follow safety messages  
carefully.  
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:  
Front and Rear Deflectors are installed and in good, working condition;  
Mower Head is running close to and parallel to the ground without exposed Blades;  
Passersby are outside the existing thrown-object zone;  
All areas have been thoroughly inspected and all foreign material such as rocks, cans,  
glass, and general debris has been removed.  
NOTE: Where there are grass and weeds high enough to hide debris that could be struck  
by the blades, the area should be: inspected and large debris removed, mowed at an  
intermediate height, inspected closely with any remaining dsebris being removed, and  
mowed again at desired final height. (SBM-1)  
9.2 Operating Speed and Ground Speed  
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not  
exceed 2 MPH while operating. Operate the mower at its full rated PTO speed to maintain blade speed for a  
clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear  
to provide the required operating and desired ground speed. Make sure that the mower is operating at its full  
rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near  
idle.  
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The  
operator may be required to experiment with several gear range combinations to determine the best gear and  
range which provides the most ideal performance from the implement and most efficient tractor operation. As  
the severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to  
maintain the proper operating PTO speed. OPS-B- 0009  
Mow at the speed that you can safely operate and control the tractor and mower. The  
correct mowing speed depends on terrain condition and grass type, density, and height of  
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds  
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when  
debris and foreign objects are to be avoided. (SGM-7)

OPERATION  
9.3 Operating the Attached Mower Heads  
The boom can attach to and operate multiple heads one at a time for a wide range of vegetation control  
applications. The attached heads are designed for different applications. The head should be selected based  
on the mowing application and the location that the unit is being operated.  
Refer to the Assembly Section of this manual to ensure the head is properly attached to the boom hitch and  
hydraulic lines are properly connected. OPS-B- 0010  
There are obvious and hidden potential hazards in the operation of this  
Mower. REMEMBER! This machine is often operated in heavy brush  
and in heavy weeds. The Blades of this Mower can throw objects if  
shields are not properly installed and maintained. Serious injury or even death may occur  
unless care is taken to insure the safety of the operator, bystanders, or passersby in the  
area. Do not operate this machine with anyone in the immediate area. Stop mowing if  
anyone is within 100 yards of mower. (SGM-2)  
Rotary Cutter  
The Rotary Cutting Head is rated to cut  
vegetation up to 5” in diameter.  
Objects tend to be thrown out from under the  
head in the direction of blade rotation and  
toward the raised edge of the shroud. Avoid  
cutting with the head tilted at an angle that  
objects would be thrown towards the unit  
operator position.  
When clearing brush and small trees, operate  
unit at 1 mph ground speed and position cutter  
head at an angle that will cut 2’ to 3’ into the  
growth. Make the first pass just above ground  
level. This will remove the low branches and  
allow operator a better view of the material to  
plan for the next pass. After repeated passes,  
each elevated approximatly 4’ above the last, the main trunks of the trees will be exposed and they can be  
cut as desired. This avoids clogging the head with cut and mulched material.  
Open the hydraulically operated door to allow blades to reach large diameter vegetation. Operate the  
mower with the door closed when cutting grass, weeds, and light brush to reduce thrown objects for safer  
mower operation.  
When operating near the ground or when mulching be particularly careful that there are no bystanders or  
animals with a 100 yards. Debri tends to fly out at great speed and can injure or even cause death.

OPERATION  
Before transporting the tractor on a public roadway  
or boarding a trailer for transport, the tractor brake  
pedals should be locked together. Locking the  
pedals ensures that both wheels brake  
simultaneously while stopping, especially when  
making an emergency stop.  
Use extreme caution and avoid hard applications of  
the tractor brakes when towing heavy loads at road  
speeds. Never tow the implement at speeds  
greater than 20 MPH (25 kph). OPS-U- 0018  
11.1 Transporting on Public Roadways  
Extreme caution should be used when transporting the tractor and mower on public roadways. The tractor  
must be equipped with all required safety warning features including a SMV emblem and flashing warning  
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive  
drivers and most drivers will not be looking out for you, therefore, you must look out for them. Check your side  
view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower  
speed. Be extremely cautious when the piece of equipment that you are towing, is wider than the tractor tire  
width and/or extends beyond your lane of the road. OPS-B- 0014  
The SMV (Slow-Moving Vehicle) emblem is  
universal symbol used to alert drivers of the  
presence of equipment traveling on roadways at a  
slow speed. SMV signs are a triangular bright  
orange with reflective red trim for both easy day and  
night visibility. Make sure the SMV sign is clean and  
visible from the rear of the unit before transporting  
the tractor and implement on a public roadway.  
Replace the SMV emblem if faded, damaged, or no  
longer reflective. OPS-U- 0020  
Never allow children or other persons to ride on the Tractor or Implement.  
Falling off can result in serious injury or death. (SG-10)

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in  
such a way as to be clearly visible and legible. When transporting the  
Equipment use the Tractor flashing warning lights and follow all local  
traffic regulations. (SG-6)  
Make sure that all tractor flashing warning lights,  
headlights, and brake/taillights are functioning  
properly before proceeding onto public roads.  
While newer model tractors have plenty of lighting  
to provide warning signals and operating lighting,  
most older models where only equipped with  
operating lights. Consult an authorized tractor  
dealer for lighting kits and modifications available  
to upgrade the lighting on older tractor models.  
OPS-B- 0015  
When operating on public roads, have  
consideration for other road users. Pull to the side  
of the road occasionally to allow all following traffic  
to pass. Do not exceed the legal speed limit set in  
your country for agricultural tractors. Always stay  
alert when transporting the tractor and mower on  
public roads. Especially in busy cities, the boom  
extends to right farther then the tractors width, so  
be careful there are no bystanders, poles,large  
obstructions or any vehicles that may be in path of  
the mower head on boom. Use caution and reduce  
speed if other vehicles or pedestrians are in the  
area. OPS-B- 0016  
When transporting Boom Mower on a truck or trailer, the height or width  
may exceed legal limits when the boom is in the transport position.  
Contact with side or overhead structures or power lines can cause  
property damage or serious injury or death. If necessary lower boom to  
reduce height and/or remove mowing head to reduce width to the legal  
limits. (SBM-8)

OPERATION  
12.TROUBLESHOOTING GUIDE  
HYDRAULIC CYLINDER NOT WORKING - Check level of hydraulic fluid (see sight gauge on tank). Check to  
see if pump is functioning properly by attempting to use another cylinder or pressure gauge. If pump is working  
properly, check the pressure on the line. The relief valve may be by-passing fluid at too low pressures. If  
cylinder is still not functioning properly, check the line for stoppage. The pistons in hydraulic cylinders are  
virtually trouble-free, but occasionally one will have a scored wall and allow oil to flow around the piston. In this  
case, replace the cylinder.  
NOTE: Refer to repair parts section on valve bank settings on individual relief cartridges.  
HYDRAULIC MOTOR NOT WORKING - Check lines for kinks or pinched place. If the motor is “bogging  
down” under load, recheck the relief valve setting on the cutter valve - 2500 P.S.I.  
HYDRAULIC VALVE - Failures in the hydraulic system are almost always caused by other elements in the  
system other than the valve; so the entire system should be checked before the valve is changed. A  
malfunction In any hydraulic valve section will require replacement of that section (but not the replacement of  
the valve bank) since the insides are honed to fit individually. Attachments such as the relief valves and detent  
may be serviced individually.  
STRUCTURAL MEMBERS - Failure in structural members generally results from rough treatment. While they  
are constructed to withstand abuse, they cannot be made strong enough to withstand abnormal abuse. The  
factory does not warrant these parts to any extent other than in normal use in grass, weeds, brush, small  
bushes, and small trees which the unit is designed to cut.

MAINTENANCE  
If possible, it is best to check the spindle oil level after the machine has been operated. This will allow the oil to  
flow easier.  
Position the head vertical as shown in Figure MntP-B-0002. Remove the breather/check plug from the square  
portion of the spindle housing. Remove the fill plug and fill with NLGI 000 grease (Alamo P/N 00765444) until  
it comes out of the breather/check hole in the square portion of the spindle housing. See Figure MntP-B-  
0003. Replace breather/check plug and fill plug.  
FML 100 HEAD:  
Position the head horizontal and lower to the ground. Remove the filler/breather from the top of the spindle  
housing. Remove the check plug from the side of the housing. Fill the spindle through the top hole until it  
comes out of the side check hole. Replace the filler/breather and check plug.  
HYDRAULIC OIL, FILTERS, AND COMPONENTS  
Filters and Oil - Change the Pressure Filter after the first 100 hours of operation. Change the filter again at 400  
hours or every 12 months. Change the oil after the first 400 hours of operation. After that, the oil every 800  
hours or every 12 months. Refer to decal for proper oil vioscosity for operating conditions.  
If the Mower head cuts off or loses power it may be an indication that the Pressure Filter needs to be changed  
Change Filter element of filter on pressure port of valve when indicator is red in color. Indicator can be found on  
top of the filter housing. Replacement Filter element Part No. is 02976067.  
Keep all hoses and adapters tight. Repair any leaks immediately. Do not overtighten hose end fittings.

MAINTENANCE  
HARDWARE  
Most nuts and bolts will stay tight and therefore need only periodic checking. However, the following nuts and  
bolts are extremely important and should receive special attention:  
Spindle Housing Bolts: Tighten to 400 Ft./Lbs. Torque  
Blade Bolts: Tighten to 400 Ft./Lbs. Torque  
Blade Bar To Spindle Bolts: Tighten to 400 Ft./Lbs. Torque  
Be certain to clamp or securely support the Spindle Housing and subassemblies to prevent  
injuries to hands and feet due to inadvertent dropping or falling over.  
Always wear safety glasses and gloves to prevent eye and hand injury when chiseling or  
hammering on metal components. Hardened metal will chip unexpectedly.  
An assembled spindle housing is quite heavy. Use a hoist or get help to handle them safely.  
Lift carefully and properly using your legs to lift - NOT YOUR BACK.

MAINTENANCE  
ASSEMBLY  
Make sure all parts are clean and free of any contamination  
Install Bearing Cups (3 & 4) into Spindle Housing (2) using a suitable bearing driver to seat the cups. Caution  
must be taken not to damage the cup or spindle housing, cups must be fully seated. If Cups are damaged  
during installation or not fully seated, bearing and spindle assembly life are greatly reduced!  
Never drive against bearing surface! Never used the mating bearing cone to seat the cup!  
Once the Lower Cup is installed, the seal may be installed. The seal should be installed with the spring  
towards the inside Press seal (7) into spindle housing, make sure seal is fully seated. Be careful not to  
damage seal!  
Press the Lower Cone (3) on the spindle shaft (1) use the proper tool when pressing the bearing onto the shaft,  
driving against the inner race and not the rollers or cage. Any damage to the bearing will cause premature  
failures of the bearing and spindle assembly.

MAINTENANCE  
Before installing the spindle (with the bearing pressed on it), lubricate the rubber portion of the seal. This will  
reduce the chance of the Seal being torn by the installation of the spindle and is a necessary step when setting  
the rolling Torque.  
Turn the Spindle Housing Upside Down and insert the spindle (with the bearing pressed onto it) into the spindle  
housing until the bearing cone contacts the cup in the Housing. During this step take care not to damage the  
seal.  
While supporting the Spindle and Housing turn the assembly over so that the assembly is setting on the  
spindle.  
Install the upper bearing (4) on the spindle shaft (1).  
After the Upper Bearing is installed, install the nut (5) with the chamfer facing up. Run the nut down against the  
bearing, but do not torque the nut at this time. Clamp the spindle Housing in a vise so that the spindle shaft  
can rotate. Tighten the nut until the spindle shaft has a rolling torque of 25 in-lbs (that is it takes 25 in-lbs to  
rotate the spindle shaft).  
Install the tanged lockwasher (6) with the outside prongs facing upward.  
Install the top nut (5) with the chamfer facing down. Block the spindle to keep it from rotating and torque the top  
nut to a minimum of 100 ft-lbs. Bend the tang of the lockwasher to fit into one of the grooves of the top nut.  
Install vent plug (8) and Grease Fitting (9).  
Fill spindle assembly with NLGI EP#2 Grease (Approx 22 oz.).

START UP PROCEDURE  
1.  
Read all safety instructions. Decals on the Machete Boom warn you of particular and multiple hazards.  
Many decals are attached close to part of the Machete Boom where there is a possible hazard. Read  
and make sure you understand the safety messages before you operate the Machete Boom. Keep all  
decals clean and readable. Replace lost or damaged decals.  
2.  
3.  
Before operating, read all the safety and operating instructions in the Operators Manual for both the  
tractor and mower.  
When the hydraulic tank has been filled and the mower unit properly assembled, the unit should be  
started up. NOTE: Make sure that no materials, tools, or jacks, have been left under the mower head.  
Make sure the front and rear of the mower are properly guarded to prevent any foreign objects from  
being thrown by the mower. All other workers should be kept a safe distance from the unit before the  
mower is started.  
4.  
5.  
Start the tractor and idle at a slow engine speed until oil is being pumped.  
Engage the Cutter Control Valve at low engine rpm and run the mower slowly for a short period until all  
air is removed from the hoses. Keep all persons WELL CLEAR of mower since Blades can THROW  
OBJECTS with great velocity for a considerable distance! KEEP CLEAR!  
6.  
7.  
With the area clear of any ground and overhead obstructions, work each cylinder on the boom one at a  
time, several times, to expel any air in the Hoses and Cylinders.  
Run the Mower Head for 5 minutes. While the tractor is idling, blocked, wearing protective clothing and  
eye protection, CAREFULLY check for leaking hydraulic fittings, hoses and ports at this point with a  
piece of cardboard, DO NOT USE YOUR HAND! If any are found stop the tractor immediately and  
correct any leaky connections.  
8.  
Check the fluid level in the Hydraulic Tank on the Tractor, and add oil if required. As the air has been  
forced out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level. Check  
your Tractors Operators Manual for the proper level and type of oil to be used.

MAINTENANCE  
TIMBER CAT HEAD  
Lubrication/Daily Checks (Figure Mnt-0007)  
Lubricate the grease fittings on top of the blade bar  
every 4 hours. See Figure Mnt-0007.  
Every 8 hours, lubricate the cylinder grease fitting  
through the top slot in the cover. See Figure Mnt-  
B-0007. Every 8 hours, check all bolts and nuts for  
proper tightness. Tighten any bolt or nut found to  
be loose.  
Periodically check the hydraulic  
connections for oil leaks. Visually inspect the hoses  
for damage and replace as necessary. Periodically  
inspect blade stroke adjustment by running the  
head at normal operating speed (540 PTO RPM)  
and checking that the upper and lower blades line-up perfectly the instant of reversal (when they change  
direction).  
Improper adjustment is also indicated by an abnormally high shock load on the hydraulic system during blade  
reversal. This is due to the hydraulic cylinder reaching its stroke limit, causing the pressure relief reversing  
components to engage. Continuous operation in this mode will result in oil overheating and premature failure  
of components. If the unit is improperly adjusted, follow the stroke adjustment procedures below.  
Stroke Adjustment (Figure Mnt-B-0008)  
Position the head in a safe area for operation. If  
necessary, barricade the head to prevent contact  
while it is being operated.  
Remove the cover and loosen the two jam nuts  
(Item 1). See Figure Mnt-B-0008. Screw the two  
spring bolt assemblies (Item 2) in toward the valve  
push buttons. Start the unit and bring the speed up  
to normal operating speed (540 PTO RPM). Check  
the blade overlap. Adjust the spring bolt assemblies  
(Item 2), one by one until the upper and lower  
blades perfectly align in the instant of reversal.  
Never adjust the bolt assemblies to a point where  
the hydraulic cylinder reaches it's stroke limit! This is indicated by an abnormally high shock load on the  
hydraulic system due to the pressure relief reversing components being engaged. Continuous operation in this  
mode will cause premature component failure and hydraulic oil overheat. Once proper adjustment has been  
achieved, tighten the jam nuts (Item 1) and replace cover.

MAINTENANCE  
BUZZBAR HEAD  
BLADES  
For best performance, have blades set and sharpened when they begin to dull. Blades can be touched up with  
a grinder or file between sharpenings.  
To extend the life of the blade, remove resin accumulations. When the resin builds up, the blades will "burn" in  
the cut, causing the blades to overheat and warp. When cutting some types of trees, blades will need to be  
cleaned every few hours. To remove the resin, use oven cleaner or lacquer thinner with a Scotch-Brite pad or  
steel wool. Apply these products carefully since many of them will remove paint from your BuzzBar. Always  
follow manufacturer's instructions for safe use.  
Blades should turn clockwise when views from the top.  
See illustration below for hose routing.  
LUBRICATION  
Grease each spindle with one pump of high quality lithium grease weekly. More than one pump is unnecessary  
and will cause extra grease to spill from the relief.  
Grease fittings are located in front of the machine, just above the blades.

BELT TENSION ADJUSTMENT (Figure Mnt-B-0010)  
Loosen nuts on the 4 studs and the jam nut.  
Use a hand wrench or socket to tension the belts.  
Never use power or air equipment to tighten belt! This could cause damage to belt, sheave,  
shaft and bearings  
Once the belts begin to tighten, small adjustments will produce large changes in tension.  
Belts should be tensioned 15-20 lbs of force for 5/16 inches deflection.  
Tighten nuts on studs and jam nut to hold tension.

LUBRICATION  
Grease each spindle with one pump of high quality lithium grease weekly. More than one pump is  
unnecessary and will cause a mess when extra grease squirts out of the relief.  
Grease fittings are on front of machine, just above the blades.  
Belts:  
Check the belt tension daily. Your buzzbar is equipped with high performance Micro-V belts that run much  
tighter than regular V-belts. The belts should be tensioned to 15 to 20 lbs. of force for 5/16 of an inch of  
deflection.  
If belts begin to slip, check tension.  
To tighten the belts, loosen the four nuts that hold the spindle to the body of the machine. Then use a hand  
wrench or socket to turn the bolt that tensions the belt. Never use power tools to tighten belt. Once the belts  
begin to tighten, small adjustments will produce large changes in belt tension.  
Too much tension can cause premature bearing, sheave, and belt damage.

Tensioning Drive Belts  
The rotor shaft is driven from the gear motor via “V” belts which are adjustable for tension. After stopping the  
tractor engine, remove the drive guards to tighten the belts. Check the tension by applying a force of 6.17 -  
7.72 lbs at right angles to the belt in the centre of the two pulleys. If the deflection is great than 1/4” then  
release the motor mounting plate screws and adjuster locknut and screw the adjuster to tighten the belts until  
the deflection is 1/4”. Then, tighten the locknut, recheck the belt tension, and replace the belt cover.  
IMPORTANT: Do not overtighten belt as this may cause premature failure of the rotor shaft and motor  
bearings.

General Information on Flail Mower Vibration  
FLAIL MOWERS  
INFORMATION BULLETIN NO. 5  
EXCESSIVE VIBRATION  
Vibration is a MONSTER and if allowed to continue unchecked, can cause the complete break-up of a machine  
in a very short time.  
A properly operated Flail Mower will produce very little vibration. If vibration does occur, the mower should be  
stopped and the trouble corrected, as warranty does not cover failures resulting from continued operation after  
something happens to cause the mower to vibrate excessively.  
Vibration is caused by a rotating part which is out of balance. This could be the cutter shaft or, on those  
models having a universal slip joint assembly drive shaft, from the drive shaft.  
If the two extreme ends of the drive shaft, (the yoke splines which fit on the tractor power take off shaft and on  
the mower gear box driven shaft), are not parallel, vibration will be evident.  
This is because of the mechanics of a universal drive wherein the rotational speed thru a universal joint is not  
uniform. If the ends of a universal drive shaft are parallel, the uneven rotation effect is cancelled out and the  
machine being driven will be driven at a uniform rate of speed. However, if the ends are not parallel, the  
uneven rotation effect may be multiplied, resulting in a speeding up and slowing down of the entire mower  
system (gear box, extension shaft, pulleys, belt, and cutter shaft) each revolution. This effect can be readily  
noticed if the mower, while running, is raised to an extreme height on the tractor lift.  
For smoothest operation, the tilt of the mower should be adjusted (on a 3-point hitch, by adjusting the length of  
the top link between the tractor and the mower) so that the ends of the drive shaft are parallel when the mower  
is down in operating position. Raising the mower, while running, to extreme heights on the lift should be  
avoided.  
To check where the vibration is originating, first be sure the ends of the universal drive shaft are parallel. Then,  
if vibration is still present, remove the drive belt and run the mower. If vibration is still present, it most likely is  
coming from and caused by a bent drive shaft. If so, the shaft should be replaced or straightened. If the  
vibration is gone - the drive portion of the mower is running smoothly - then the vibration is probably coming  
from the cutter shaft (it could be a pulley out of balance or a faulty belt with a varying cross section, but this is  
not likely).

MAINTENANCE  
The cutter shaft will run out of balance if:  
1.  
Wire, rope, string, rags, etc., around the cutter shaft, are holding the knives in a folded back position.  
Remove such foreign objects and be sure all knives are free to swing to the extended position.  
2.  
3.  
Knives are missing or broken. Replace missing or broken knives.  
Knife hanger lugs are broken off shaft. This condition usually results from continued operation in con-  
tact with large hard objects where the knife hanger lugs themselves are hitting the hard objects. Lugs  
should be replaced using arc welding equipment so as not to direct too much heat in one area of the  
shaft.  
4.  
5.  
Cutter shaft ball bearings are worn enough to have radial "play" in them. Replace ball bearing and  
other worn parts to eliminate "play".  
Shaft is bent. The shafts are straight within a couple of thousandths of an inch when they are made. It  
is possible that they will become bent in use, such as if the shaft is hooked on a stump while the tractor  
is moving forward at a good speed.  
6.  
Shafts are operated at improper speed. Rotating shafts have what is known as a natural period of  
vibration. The same is true of the cutter shafts on the Flail Mowers.  
The actual speed at which the harmonic will occur will vary with each mower and each installation. To avoid  
this harmonic vibration when operating the mower, it may be necessary to adjust the engine speed of the  
tractor up or down.  
Some units have a harmonic which occurs below the nominal operating speed. On these units, it will be  
noticed that there is always a little vibration at a particular RPM as the mower is being sped up to operating  
speed. This occurs as the shaft passes through its normal harmonic vibration point. As long as the mower is  
opened at the proper speed, then harmonic vibration will not be an issue.  
Be certain to clamp or securely support the Spindle Housing and sub-assemblies to prevent  
injuries to hands and feet due to inadvertent dropping or falling over.  
Always wear safety glasses and gloves to prevent eye and hand injury when chiseling or  
hammering on metal components. Hardened metal will chip un-expected.  
An assembled spindle housing is quite heavy. Use a hoist or get help to handle them safely.  
Lift carefully and properly using your legs to lift - NOT YOUR BACK.

Spindle shafts: Inspect the threads, internal splines, and bearing journals for damage or wear. Replace if  
damaged or worn.  
Bearing ring: Inspect the ring for wear in the area of seal contact. Replace if a wear groove exists.  
Housing: Inspect the bearing cup bores, ring grooves, etc. for wear or damage. Repair or replace if any

ASSEMBLY  
Tools needed:  
Hand tools Hydraulic press, Inch pound torque wrench, Seal Installers, Bearing drivers (do not use punches to  
install bearings) Adjusting nut socket 2-3/4" ID x 8" long, 16 Ga. tubing  
NOTE: This procedure should not be attempted in the field due to the need for tools normally only found in the  
shop.  
1.  
2.  
Place upper bearing cones in bearing oven.  
Seat bearing cups (outer races) in housing using a press and proper installation tools in good  
condition. CUPS MUST BE FULLY SEATED. If bearing cup cocks in bore and seizes, do not continue  
to assemble spindle.  
3.  
4.  
Lubricate lower bearing cone with LPS.  
Coat the outside of the seal with silicone and install the lower bearing, seal, and retaining ring into the  
housing, using the correct seal installer.  
5.  
Place a light film of silicon or permatex on the inside diameter of the bearing ring and seat the ring on  
the spindle shaft, using the proper tool and press.  
6.  
7.  
Lightly lubricate the lip of the seal.  
Using the 2-3/4" tubing to prevent the cup and cone from contacting each other, press the spindle  
shaft through the lower bearing and seal. Make sure the bearing is seated against the bearing ring.  
8.  
9.  
Place Locktite on threads of the bearing adjusting nut (flange nut).  
Using gloves, install the heated upper bearing cone on the shaft immediately and push it all the way  
against the cup. Lubricate the bearing with LPS.  
10.  
Install the bearing adjusting nut. Tighten the nut until the spindle shaft can not be turned. Loosen the  
nut 1/4 turn. Place a soft, clean cloth over the top of the spindle assembly. Place an aluminum block  
over the end of the spindle shaft and strike the block with a hammer to loosen the bearing.

MAINTENANCE  
11.  
Remove the cloth, being careful not to allow any contamination into the spindle. Tighten the nut until a  
rolling torque of 16-21 inch-pounds is reached. (If the seal was not lubricated, add 10 inch-pounds).  
12.  
13.  
Stake the nut with a blunt, round nosed punch. Do not tear the nut.  
Install the grease fitting into the hole in the center of the housing (between the bearings) and fill the  
housing with EP#2 grease, stopping when the lubricant covers the upper bearing (approximately 11  
oz.).  
14.  
15.  
Install the breather plug in the top hole.  
Install spindle in mower deck and assemble in reverse order. Torque the blade bar or pan bolts to 400  
ft-lbs. Torque motor to spindle bolts to 85 ft-lbs. Torque spindle to deck bolts at 175 ft-lbs.

1. Provide a Roll-Over-Protective Structure that meets the requirements of this Standard; and  
2. Provide Seat belts that meet the requirements of this paragraph of this Standard and SAE J4C; and  
3. Ensure that each employee uses such Seat belt while the tractor is moving; and  
4. Ensure that each employee tightens the Seat belt sufficiently to confine the employee to the protected  
area provided by the ROPS.  
REQUIRED OF THE OPERATOR  
1. Securely fasten seat belt if the tractor has a ROPS.  
2. Where possible, avoid operating the tractor near ditches, embankments, and holes.  
3. Reduce speed when turning, crossing slopes, and on rough, slick, or muddy surfaces.  
4. Stay off slopes too steep for safe operation.  
5. Watch where you are going - especially at row ends, on roads, and around trees.  
6. Do not permit others to ride.  
7. Operate the tractor smoothly - no jerky turns, starts, or stops.

9. When the tractor is stopped, set brakes securely and use park lock, if available.  
Keep children away from danger all day, every day...  
Equip tractors with rollover protection (ROPS) and keep all machinery  
guards in place...  
Please work, drive, play and live each day with care and concern for  
your safety and that of your family and fellow citizens.
