blade contact. (SGM-3)
Safety Section 1-7
SAFETY
DANGER!
WARNING!
WARNING!
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)
WARNING!
WARNING!
WARNING!
Mow at the speed that you can safely operate and control the tractor and
mower. Safe mowing speed depends on terrain condition and grass type,
density, and height of cut. Normal ground speed range is from 0 to 5 mph.
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 put hands or feet under mower decks. Blade Contact can result
serious injury or even death. Stay away until all motion has stopped and
the decks are securely blocked up. (SGM-9)
DANGER!

DANGER!
DANGER!
Rotary and Flail 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:
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.
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 debris being removed, and mowed again at desired final height. (SBM-1)
(SBM-2)
DANGER!
WARNING!
WARNING!
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)
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.

the spacer plate. If your pulley has the (4) four holes needed to mount the spacer, your pulley is
the correct one needed. If your pulley does not have the (4) four holes in the pulley, you will need
to order the correct pulley, washer and bolt from John Deere.
PARTS REQUIRED TO PURCHASE FROM JOHN DEERE:
Pulley from JD - R516320
Washer from JD - R517237
Bolt from JD - R516648
Torque on the pulley bolt with locktite is 369 lb-ft.
Solution:
1. Clean nose of crankshaft using TY16285 clean and cure primer.
2. Apply a light 2-3mm bead of TY15969 retaining compound around the leading edge of the
crankshaft nose.
3. Dip damper mounting capscrew in clean SAE30 engine oil (Always use a new capscrew).
4. Position damper/pulley on the crankshaft and thread capscrew up tight (do not rely on the
capscrew to pull the pulley straight onto the taper).
5. Tighten capscrew to specification 500Nm (369lb-ft) (the engine will most likely have to be
pinned).
6. Measure run-out on the pulley, spec is 0.003” or less.

monitoring”. The Deck Shield section does not have “active fault monitoring”. The joystick is
unchanged and provides a ratio-metric voltage signal. The neutral signal voltage is half or 50%
of tractor supply voltage. A 25% signal voltage will shift the valve spool to full “A-Port”, and 75%
signal voltage will shift the spool to full “B-Port” in the Main, Secondary, and Swivel valve
sections. On the Deck Roll function a 34% signal voltage will shift the valve spool to full “A-Port”
and a 68% signal voltage will shift the spool to full “B-port”. If an actuator with active fault
monitoring receives a signal from the joystick that is less than 15% or greater than 85% of supply
voltage the actuator will “fault out” and shut down. Also if there is an internal failure in the
actuator or if the spool position is greater than that specified by the signal voltage from the
joystick, the actuator will “fault out” and shut down. An “active fault” condition causes the
actuator to drive the spool to neutral, shut down, and activate a “red” LED on the top of the
actuator. The active fault can be canceled by simply cycling the Master Switch “OFF” and then
“ON”, which resets the fault monitoring, and causes the LED on top of the actuator be “green”
again..
The joystick control is equipped with signal adaption potentiometers.
These provide the capability to individually adjust the oil flow to each boom function. It is
important that the boom functions do not travel too fast. Excessive boom speed can reduce the
stability of the unit and decrease operator control.
Note: Use a Phillips screw driver and be sure to adjust the screws carefully! DO NOT turn
the potentiometers beyond their stopping point, potentiometers are very delicate! Tu rning the “A”
or “B” port potentiometers clockwise increases the oil flow to increase the boom function speed,
and turning them counterclockwise decreases the oil flow to decrease the boom function speed.
See the graphic on the next few pages for help in adjusting.
Assembly Section 2-25
ASSEMBLY
Run tractor at normal operating RPM to adjust the settings as follows.
Set the dead band compensation potentiometer first.
Set the dead band compensation potentiometer at 50%, or halfway between full clockwise and
full counter-clockwise.
Setting Signal Adaptation Potentiometers:
Disconnect the Deutsch connectors from the actuators of the valve. Use a Volt/Ohm meter to
measure signal voltage and adjust the signal adaptation potentiometers as needed. Pin #4 is
tractor supply voltage. Pin #1 is signal voltage from the joystick, and pin #3 is ground. First
measure supply voltage between pins 4 and 3 . Then measure signal volt age between pins 1 and
3 while indexing the joystick function fully in both the “A” and “B” port direction. Divide the signal
voltage by the supply voltage to get signal voltage as a % of supply voltage. This percentage
should not be less than 25% or greater than 75% for the Main Boom, Secondary Boom, or Swivel
function. This percentage should not be less than 30% or greater than 62% for the Deck Roll
function. Note these initial settings for the Deck Roll function should prevent the spool from
shifting into float. After making this first adjustment to deck roll if the spool still goes into float,
adjust the “B” port screw additionally counterclockwise.
Reconnect Deutsch connectors on control cables to actuators on Danfoss valve. Run tractor
until hydraulic system is at operating temperature. Now refine the adjustments of the signal
adaptation potentiometers for both “A” and “B” ports for all proportional functions to achieve the
following function times. Note: turning potentiometer clockwise increases the flow or the function
speed, and turning them counter-clockwise decreases the flow or the function speed. Note, if
during this procedure the trim potentiometer is set to full “counterclockwise” but the function is
still too fast, use the mechanical stops at the manual actuator end of the valve section to further
limit flow. Turn limit screw in or clockwise to limit flow. The upper limit screw limits flow to “Bport”, and the lower limit screw limits flow to “A-port”. However DO NOT adjust the limit screw on
“B-port” of deck roll function. Limiting “B-port” will prevent “float” function.

FINAL PREPARATION FOR OPERATION
Place operators safety and operation decals on the steering column and side counsel where
they are clearly visible to the operator. These decals should be understood by each operator of
the machine in conjunction with the safety and operation section of this book. The decals are to
be maintaned in good condition as a reminder to the operator, and should be replaced if
damaged.
Finally, all bosses, pins and pivot points will need to be greased as instructed in the
maintenance section of this manual. The hydraulic reservoir can also be filled with the
recommended fluid (see maintenance section) and the filter installed in the top of the tank.
Double check all fittings and fasteners BEFORE starting tractor. Also secure any loose hoses
together with zip ties and wrap with split hoses where friction may occur on the hoses.
BEFORE starting or operating the tractor you must read and understand the
safety and operation sections of this manual completely.
BE SURE THE BALL VALVES ARE OPEN! Start tractor and allow instruments to stabilize.
Using a piece of paper or cardboard as noted in the safety and maintenance sections, check all
fittings and connections for hydraulic leaks.
If a leak is found, you must shut down the tractor, set the cutter on the ground. Before
attempting to fix the leak, you must actuate the lift valve handles several times to relieve any
pressure in the lines.
Before operating the mower , the cutte r head and boom should be slowly moved throughout
the full range of motion. Watch for any condition that would cause pinching or excess stress on
the hoses. The steering and front axle travel should also be carefully moved through their full
range of motion. If any condition occurs in which the hoses contact the tires, the steering and /
or front axle travel may need to be limited as described in the tractor operators manual. This
should also be done if the tires rub, or are extremely close to any other p art of the mowe r such as
the hydraulic tank or draft beam. This may include adding shims, or adjusting stop bolts in the
tractor front to solve the problem. While checking motion, you should also check that the control
circuits are connected according to the operators decal for the valve handles.
MOWER TESTING
Take the tractor to a place free of loose objects on the ground. Operate the cylinders through
their full range of motion again, to clear the lines of air. Follow the instructions in the operation
section to operate the mower. Vibration of the mower should be minimal at all times. After a 5
minute test run, the knife bolts should be retorqued and once again after the first few hours of
operation.
If any parts of this assembly section, or any other section of this manual are
not clearly understood you must contact your dealer or the address on the front of
this manual for assistance!

OPERATION
2.4 T ractor 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 f or 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.
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

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.

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 you r speed. When operating in traf fic always use
the Tractor’s flashing warning lights and red uce your speed. Be a ware of traf fic around yo u
and watch out for the other guy.

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

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.

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 freewheel downhill.

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)
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 T O 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 obstructions, 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 eq uipped with a polycarbonate safety-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
300 feet (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 objec ts. If you are unab le to clear ly see thes e type of ite ms
discontinue mowing.

OPERATION
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-08)
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 wear
safety glasses and a hard hat. (Ops-0005-MISC)
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, boulders, rocks, culverts, stumps or metal objects. Mark the
inspected area with flags. If the area is dense and cannot be walked thoro ug hly it may b e necessar y to in sp ect
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 d angerous to work the cutter in an area that has
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 sec ond
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 mark ed and car efully avo ide d b y th e
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-05)
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-06)
OPERATION
Boom Operation Section 3-33
©2011 Alamo Group Inc.
OPERATION
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-07)
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 5 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 p an el for th e e ngi ne sp eed a nd gear
to provide the required operating and desired gr oun d 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 be st 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. 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-07)
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 dif fer ent applications. The h ead 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 300 feet
of mower.
(SGM-02)
OPERATION
Boom Operation Section 3-34

OPERATION
9.4 Mower Operation
The rotating parts in this machine have been design ed and tested for rugged use. However, they could fail
upon impact with heavy solid objects-such as steel guard rails, concrete abutments,etc., causing th em to be
thrown at a very high velocity. Never allow cutter head to contact such objects. Inspecting the cutting area for
such objects and removing them prior to mowing can help eliminate these potiential hazards.
Once on location, lower the mower deck slightly above the material to be cut, so the mower does not have to
start under a load. With the tractor at an idle, engage mower. Bring tractor R.P.M. up to 1900-2200 R.P.M. and
slowly lower deck to ground level.
A flail mower deck should be carried so that the part of the deck weight is carried by the boom and part carried
by the ground roller, when moving on the ground. When the flail mower is carried this way, the ground roller
follows the contour of the ground more easily during mowing operations.
The rotary mower deck should always be carried rather th an dragged on the skid shoes when mowing on the
ground. Dragging the rotary mower deck increases the side loads on the boom, decreases the horsepower
available to the cutter head, and reduces the ability of the accumulator the carry par t of the we ight of the boo m
during mowing operations.
When rotating parts are in motion, serious injury may occur if caution is not used or danger is
not recognized. Never allow bystanders within 300 feet of the machine when in operation.
Extreme care should be taken when operating near loose objects-such as gravel, rocks, and
debris. These conditions should be avoided.
OPERATION
9.5 50” & 60” Boom Rotary
The 50” & 60” boom rotary brush mower was
designed for cutting brush and foliage up to 6
inches in diameter or multiple branches that have a
total cross section area equivalent to one 6 inch
branch.
During mower operation, the hand throttle must be
used to maintain engine speed at 190 0-2200 R.P.M.
This prevents radical changes in mower spindles
speed, reducing the possibility of cutter assembly
damage.
The horizontal positioning action of the boom is
designed to position the cutting head and provide a
limited pressure relief when excessive pressure is
applied to the boom. Do not force the cutting head
into heavy branches or stumps. Damage to the unit may result.
When using the rotary cutting head for trimmin g trees and shrubs, let the mower saw into them.
Do not lower the mower head down directly into a tree or stump. The mower blades are
designed to cut with the end, and misuse can cause damage to the blade and a hazardous
situation for the operator.
Powering the boom down, forcing mower deck onto ground may damage mower deck and it’s
attachment to the boom, creating a potentially hazardous situation.
To ensure a clean cut, engine speed should be maintained at approximately 1900-2200 R.P.M. If the tractor
slows to less than 1800 R.P.M., shift to the next lower gear. DO NOT ride the clutch, this will cause premature
clutch failure. The engine should not be operated at any time at more than 2400 R.P.M. on the tractor
tachometer.
Boom Operation Section 3-35
©2011 Alamo Group Inc.
OPERATION
For cutting brush, it is usually best to stop the tractor and swivel the boom and mower into foilage. The
horizontal positioning action of the boom is designed to position the cutting head and provide a limited
pressure relief when excessive pressure is applied to the boom.
DO NOT use excessive force when positioning cutting head into heavy branches or stumps.
Damage to the unit may result. It is best to let the cutter head “eat away” slowly at heavy cutting
jobs.
If foliage falls on top of mower deck causing tractor to become unstable, move the boom
“Forward” and “Out” to relieve tipping of the tractor. Lower mower deck to ground and shut
down unit. After all motion stops, remove foliage from mower deck.
The mower will operate more efficiently in tougher conditions and with less power if the knives are kept sharp.
If the mower begins to vibrate, stop the tractor, check for wire wrapped in the spindle or damaged knives.
When replacing knives, replace all knives with new knives to ensure proper balance so the mower will not
vibrate. Severe vibration will result, if knives with unequal wear are used.
Begin a pass at the top side of the trees and work down with each consecutive pass. When cutting trees and
shrubs, use a lower speed to allow the knives time to cut as well as mulch the foliage.
OPERATION
If cutter shaft jams and stops, turn mower switch to “OFF”, and swivel boom “AFT”. Normally this action will
clear the cutter head. If not, roll mowe r deck until adjacent to the secondary boom, then lower boom to rest
mower deck on ground. Shut off the tractor, set parking break, allow all motion to cease. At that point it is safe
to leave the tractor and clear the cutter heads manually.
Begin each pass at the top side of the trees and work down with each consecutive pass. Use a low speed to
allow the cutting blades time to mulch as well as cut the foliage. When the initial pass has been made,
disengage the mower, and return boom to a safe travel position. Return to starting point and make next pass,
etc..
After the first day of operation, all bolts should be checked and tightened securely. This should be done
periodically to ensure the bolts do not b ecome loose and cause damag e to the tractor or mower, or injury to the
operator.
If bystanders approach within 300 feet while mower is in operation turn mower switch “OFF”
immediately! After shutdown, never leave the tractor or a llow bystander s to approach within 300
FEET of the unit until all motion stops completely.
Boom Operation Section 3-36
©2011 Alamo Group Inc.
OPERATION
When cutting trees and brush approach material
to be cut with the head perpendicular to material.
The cutting edge of the blades should be the
only elements in contact with material. The blade
bar should not contact with material. The mower
head and blades should be moved
perpendicularly into the material rather lowering
the mower head on top of material. If the blade
bar edges are gouged or rounded from wear, the
mower head is being used incorrectly in an
abusive manner . The blad e bar is n ot intended to
cut material or to be a wear item like the blades.
Do Not allow the blades or blade bar to contact
the ground, rocks or solid objects. Contact with
the ground can result in rocks and solid objects
being thrown out from under the mower head
which can cause serious injuries to the operator
and bystanders. This type of operation can lead
to bent or broken blade bars, broken blade bolts
and broken blade bar assembly bolts which can
be dangerous to the operator and bystanders.
OPERATION
(OPS-R-220)
9.6 50” Boom Flail
The 50’ boom flail mower was designed for cutting
brush and foliage up to 3 inches in diameter or
multiple branches that have a total cross section
area equivalent to one 3 inch branch. Cutting
multiple limbs at the same time may overload the
mower causing it to slow down or stall completely.
Regardless of the size of material being cut, the
cutter shaft speed must be maintained. To ensure
that the cutter shaft is running at maximum speed,
run the tractor at full throttle during mowing
operations. If the cutter shaft slows to the point that
the knives are folding back, move the mower head
away from the foliage and allow the cutter shaft to
regain full speed.
Operating the mower in a manner that allows the knives to continually fold back or allowing
knive lugs to contact foliage will cause permanent damage to the cutter shaft drum, knives, and
knife attachment parts.
The 50” boom flail cutter shaft is designed for standard rotation (same rotation as the tractor
wheels during forward travel). Never operate the cutter shaft in reverse rotation. Operating
this mower in reverse rotation may cause objects to be thrown out the front of the mower head.
The 50” boom flail equipped with free swinging brush knives is intended for brush cutting only.
Cutting grass is not recommended.

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.

All Safety Shields, Guards and Safety devices including (but not
limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox
Shields, PTO integral shields, and Retractable Door Shields should
be used and maintained in good working condition. All safety devices should be
inspected carefully at least daily for missing or broken components. Missing, broken,
or worn items must be replaced at once to reduce the possibility of injury or death
from thrown objects, entanglement, or blade contact.
(SGM-3)
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.

9.7 63” Boom Flail
The 63” boom flail mower was designed for cutting
grass. The cutter shaft speed must be maintained
for proper cutting. To insure that the cutter shaft is
rotating at maximum speed, run tractor at full
throttle during mowing operations. If cutter shaft
slows to the point that the knives are folding back
against the cutter shaft, move the mower head
away from the foliage and allow the cutter shaft to
regain full speed.
