In order to reduce accidents and enhance the safe operation of mowers, Alamo Industrial, in cooperation
with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower
Safety Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial
and agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the
mower, will significantly assist in this important education.
Your Authorized Alamo Industrial Dealer may have shown this video and presented you a DVD Video
when you purchased your mower. If you or any mower operator have not seen this video, Watch the
Video,Read this Operator ’s Manual, and Complete the Video Guidebook before operating your new
mower. If you do not understand any of the instructions included in the video or operator’s manual or if
you have any questions concerning safety of operation, contact your supervisor, dealer or Alamo Indus-trial.

Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted
position. 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 stan d and put the retaining pin securely in place, or pu t a secure
support under the A-Frame. Lower the implement carefully to th e ground. Do no t put hands
or feet under lifted components.
se extreme care when lowering or unfo
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines.
(S3PT-05)
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, guar d 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.
e sure you have adequate knowledge of the property you w
make yourself aware of any area underground lines or cables. Contact with buried lines o
cable could result in serious injury or death. If in doubt about buried utility lines call 811
before digging or 1-800-258-0808.
Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor
engine. Inspect the Mower to determ ine the source of the vibration. If Mower blad es 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.
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling of f the tractor --particularly during a turnover
when the operator could be pinned under the ROPS.
(SG-7)
(SFL-4)
SAFETY
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 contr ols 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)
Do not mount or dismount 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.
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 imp ene trab le glo ves ,
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.
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-15)
(SG-26)
SAFETY
Operate the Tractor and/or Implement control s 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.

remove the key. Wait until all rotating motion has stopped before dismounting.
(SG-39)
Do Not operate this equipment in areas where insects such as bees may attack you and/or
cause you to lose control of th e 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 yo u o r 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 objec ts. If you are unab le to clear ly see thes e type of ite ms
discontinue mowing.
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.
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-02)
(SGM-4)
SAFETY
reme care should be taken when operating near loose objects suc
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 carefully a vo 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)
any 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)
ow 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)
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)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed.
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 Tra ctor an d Mo we r and cl ean clip pings an d collected debris fro m
the mower deck.
(SGM-12)
SAFETY
ower is designed for certain mowing applications and is rated to cut up to a spec
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 nonvegetative 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.
Do not operate or pull the mower into standing water. When uplift or fan type mower blades
contact water they can be severely deflected downward causing possible failure of blade
resulting in serious boldly injury to the operator or by standers.
Use extreme caution when raising the Mower above ground level. Stop the Blades from
turning when the Mower is raised and passersby are within 100 yards. Raising the
Mower 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.
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet 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, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are 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 debris being removed, and
mowed again at desired final height. (This will also reduce power required to mow, reduce
SAFETY
wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and
make the final cut more uniform).
(SRM-01)
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline
which will cause accelerated wear and breakage of drive train components and could result
in possible injury from the separated Driveline sections.
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades.
(SRM-07)
(SRM-04)
Connecting or Disconnecting Implement Safety Instructions and
Practices
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches.
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been dise nga ge d. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
en attaching the Implement input driveline to the Tractor
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.
(S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly beco mes solid-it c an shorten no m ore. Bottomin g out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury.

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 o
uneven surfaces to prevent lo ss 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-02)
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.
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clea rly visible and legible. When transporti ng the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations.
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
SAFETY
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 r educe your speed. Be aware of traf fic around you
and watch out for the other guy.
Be particularly careful when transporting the Implement using the tractor. Turn curves or
go up or down hills only at a low speed and at a gradual steering angle. Make certain that
at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow
down on rough or uneven surfaces.
ow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truc k or othe r type of ve hicle. N eve r tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH.
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.
Maintenance and Service Safety Instructions and Practices
Make sure the PTO shield, integral driveline shields, and input shields
are is installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing.
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work.
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Implement. Never work on the Implement with the tractor PT O dr iveline connecte d and

The GRASS KING will attach to most tractors with Cat I or Cat II Hitch and 540 PTO RPM.
TRACTOR PREPARATION
For satisfactory operation the Grass King machine should be attached to tractors that are of sufficient size and
horse power. The Grass King flail mower requires a minim um 40 horse power and a minimum base trac tor
weight of 4500 pounds. The Grass King rotary mower requires a minimum 50 horse power and a minimum
base tractor weight of 6000 pounds.
In addition, the left rear tire should have a full charge of liquid ballast. The rotary Grass King requires that the
rear tractor tires be spread to a minimum 96 inches outside dimension.
Note: When attaching the rotary Grass King head to the tractor, it may be necessary to move the main frame
further to the right if the head h its the tire when the head is tilted up. This is done by loosening the bolts that
attach the hitch weldment to the mainframe weldment and sliding the frame to the right. It may be necessary to
loosen the pump suction line and readjust in order to prevent the hose from kinking when adjusting the frame.
In order to move the frame the maximum amount to the right, the hitch weldment attachment bolts on the right
hand side will have to be completely removed so that the hitch can be positioned on the left side of the cylinder
lug. (See A-frame illustration in the parts section).

Operate this Equipment only with a Power Unit equipped with an
approved operator Roll-Over Protective Structure (ROPS). Always
wear seat belts. Serious injury or even death could result from falling
off the Power Unit--particularly during a turnover when the operator
could be pinned under the Operator Protective Structure.
(SPU-14)
3.2 Tractor Safety Devices
If transporting or operating the tractor and mower near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the
unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning
signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tr acto r or mower. Never operate the tractor PTO with the
PTO master shield missing or in the raised position.
The horsepower required to operate the mower depends on many factors including the vegetation to be cut,
terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the
Grass king flail mower require a tractor with at least 90HP. Operating the mower with a tractor that does not
have adequate power may damage the tractor engine.
3.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at
least 1720 lbs. when attaching a 62 “ Grass King
flail and 1870 lbs. when attaching a 74” Grass King
flail.
Grass King flail mowers can attach to tractors with
a CAT I and CAT II hitch. Refer to the tractor
operator’s manual for the category of the tractor
used. If the hitch does not conform to ASAE CAT I
or CAT II dimensions, the mower may not fit or
raise properly. Consult an authorized dealer for
OPERATION
possible modification procedures to mount
nonconforming hitches.
Use the correct hitch pins for the hitch category
being used. For a Cat I hitch, 7/8” lower and 3/4”
upper diameter hitch pins are used and Cat II
hitches require 1-1/8” lower and 1” upper diameter
hitch pins. OPS-F-0036

Height from bottom hitch pin to top pin..............18”Height from bottom hitch pin to top pin............. 19”
The Grass King Flail must use a tractor with 540 RPM PTO, single remote hydraulic connection and
three-point hitch. NOTE: Remote hydraulic connection and three-point hitch must work at the same t ime. A
four-bar folding linkage allows the single hydraulic cylinder to position the flail mower from 45° down for ditch
bank trimming through 90° up for transport.
3.6 Front End Weight
Maintain a minimum of 20% total tractor weight on the tractor front end at all times. Front end weight is critical
to maintain steering ability and to prevent the front end from rearing up. Consult your authorized tractor dealer
for front weights and carriers.
Only operate the mower on a tractor equipped to operate at 540 RPM PTO speed. Tractors operating at 540
rpm will have a 1-3/8” diameter 6-spline PTO shaft stub. Refer to the tractor operator’s manual for operating
the PTO at the proper speed
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. Consult an
authorized tractor dealer to purchase and install an over-running clutch if ne eded.
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been dise nga ge d. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the mower and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized deale r fo r a

lever back and forth several times or place
the hydraulic lever in the float position to
relieve all hydraulic pressure. When
connecting the mower hydraulic lines to the
tractor, keep the hose, quick couplers, and
swivels free of dirt and other contaminants.
Wipe all dirt and other contaminant s from the
tractor hydraulic remote ports and mower
hydraulic hose coupler with a clean rag
before connecting.
2. Connect mower hydraulic hose to the tractor
remote port. Ensure the coupler locks in
place making a good connection. Different
tractor models receive hydraulic lines differently. Refer to the tractor Operator ’s Manual for connecting and operatin g hydraulics
for your particular model tractor.
Some tractor models allow the remote
hydraulic valve to be configured for single
acting cylinders. Refer to tractor operators
manual and follow the appropriate instructions for single acting cylinder operation.
3. Ensure hydraulic hoses will not contact or
become entangled with mower drivelines, do
not bind when turning, or become pinched or
kinked when operating, raising, and lowering
the mower.
OPERATION
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before releasing the wing transport locks to lower the
mower. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position until the
cylinders fully extend then place the control lever in the float position. Repeat the process several more times
to ensure wings are entirely supported by the hydraulic cylinders before releasing the transport locks and
lowering the mower.
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 imp ene trab le glo ves ,
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.
7. SETTING MOWER CUTTING HEIGHT
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower makes a
more uniform cut, distributes clippings more evenly, increases tractor efficiency, and follows the contour of
OPERATION
uneven terrain. Note: Avoid very low cutting heights, striking the ground with the blades gives the most
damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may
cause objects to be thrown out from under the mower deck.

fasteners are removed. A stuck roller could drop
unexpectedly and cause injury.
5. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
6. Lower cutter housing to the groun d and remove
lifting device.
7. Set cutting height according to procedures
above for remaining two cutter sections. Make
sure that all three rollers are set at the same
height to ensure an even cut across the entire
width of the mower.
OPERATION
Leveling Deck
To Facilitate a safe and efficient mowing
operation, the mower should be operated
parallel to the ground at all times. Never operate
if front or rear of mower is tilted upward. Objects
may be discharged at high speeds causing
possible injury or even death.
Adjust Top Link to level mower roller
adjustment. Side Skid Shoes should always be
parallel to ground throughout the full
adjustment range. Adjust cutting height of
machine by raising or lowering rear roller as
specified in Operation Section.
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades.
The driveline yoke and tractor PTO shaf t must be
dirt free and greased for easy and secure
attachment.
To connect the mower driveline to the tractor
PTO output shaft, pull the driveline yoke collar
back and align the grooves and splines of the
yoke with those of the PTO shaft. Push the
driveline yoke onto the PTO shaft, release the
locking collar, and position the yoke until the
locking collar is securely attached to the PTO
shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
OPERATION
en attaching the Implement input driveline to the Tractor
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.

mportant that the
8.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly beco mes solid-it c an shorten no m ore. Bottomin g out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury.
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 8” must be maintained.
