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.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax
AEM VHS Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to
AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please

A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to
the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and
observing certain precautions. The first section of this manual includes a list of Safety Messages that, if
followed, will help protect the operator and bystanders from injury or death. Read and understand these Safety
Messages before assembling, operating or servicing this Implement. This equipment should only be operated
by those persons who have read the manual, who are responsible and trained, and who know how to do so
responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment. The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word
are intended to warn the owner/operator of impending hazards and the degree of possible injury
faced when operating this equipment.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or repair.
(SG-1)
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU
. Only YOU can prevent serious injury or death from unsafe practices.
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards.
(SG-2)

medidas de seguridad.
The rotating parts of this machine continue to rotate even after the PTO has been turned off.
The operator should remain in the operator’s seat for 60 seconds after the brake has been
set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.
(S3PT-10)
“Wait a minute...Save a life!”
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service.
(S3PT-19)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up.
(SFL-2)
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 or 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.
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)
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Inadvertent contact with controls can cause the
Implement to shift or fall crushing themselves or others.
(SG-25)
DO NOT use drugs or alcohol immediately before or while operating the
Tractor and Implement. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or Implement,
an operator on prescription or over-the-counter medication must consult
a medical professional regarding any side effects of the medication that
would hinder their ability to operate the Equipment safely. NEVER
knowingly allow anyone to operate this equipment when their alertness or
coordination is impaired. Serious injury or death to the operator or others
could result if the operator is under the influence of drugs or alcohol.
(SG-27)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation.
(SG-32)
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death.
(SG-33)
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)
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
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 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)
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
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 may be 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)
There are obvious and hidden potential hazards in the operation of this Mower.
REMEMBER! This machine is often operated in grass 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 the mower.
(SFL-1)
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)
Equipment Operation Safety Instructions and Practices
Flail 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 300 FEET 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;
-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 wear and tear on the Mower drivetrain, spread cut material better, eliminate
streaking, and make the final cut more uniform.)
(SFL-6)
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 off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS.
(SG-7)
BEFORE leaving the tractor seat lower the implement, set the parking
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.
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are
completelystopped.
(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.
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
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 objects. If you are unable to clearly see these type of items
discontinue mowing.
(SGM-1)
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-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)
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.
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.
(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 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.
(SGM-14)
Do Not attempt to raise or lower the implement wing unless the Implement tongue is
securely attached to the Tractor drawbar. The Implement could tip over and cause
equipment damage and possible serious injury or death. Raise or Lower the mower wing
only while seated in the Tractor operator’s seat with the seat belt securely fastened.
(SRM-2)
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.
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death.
(STI-03)
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)
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.
(S3PT-15)
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 disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
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 becomes solid-it can shorten no more. Bottoming 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.
(S3PT-18)
Each Rear Wheel must have a minimum of 1,000 pounds contact with the
surface to prevent lateral instability and possible tip-over which could
result in serious bodily injury or even death. Widen the wheel tread and
add weights if needed. Refer to the mounting instructions or call customer
service if you need assistance with counterweight procedure.
(SFL-3)
Connecting or Disconnecting Implement Safety Instructions and Practices
On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached
to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and
carefully. Keep bystanders away during operations.
(STI-05)
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-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.
(S3PT-20)
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.
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)
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement or unit may overturn.
(STI-02)
Only tow 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 truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH.
(STI-06)
Secure the Implement for transport before traveling on public roads. For pull-type
Implements, secure the center axle using cylinder stops or transport pin and properly attach
a safety chain between the Implement and Tractor. Secure wings in upright position on
folding Implements using wing transport locks.
(STI-7)
SAFETY
Maintenance and Service Safety Instructions and Practices
Make sure the PTO shield, integral driveline shields, and input shields
are installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing.
(S3PT-8)
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.
(S3PT-09)
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Implement. Never work on the Implement with the tractor PTO driveline connected and
running. Rotating Parts, Blades or Drivelines could turn without warning and cause
immediate entanglement, injury or death.
(S3PT-11)
All Safety Shields, Guards and Safety devices including (but not limited
to) - the Deflectors, 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.
(SFL-5)
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)
Do not modify or alter this Implement. Do not permit anyone to modify or alter this
Implement, any of its components or any Implement function.
(SG-8)
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
(SG-14)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running.
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order.
(SG-21)
Perform service, repairs and lubrication according to the maintenance section. Ensure the
unit is properly lubricated as specified in the lubrication schedule and all bolts and nuts are
properly torqued. Failure to properly service, repair and maintain this Implement in good
operating condition could cause component failure and possible serious injury or even
death.

To assemble your new INTERSTATER and mount it to your tractor we assist you with drawings, instructions
and information, also about experiences of others and when needed just get some information or clarification
from our engineering department over the phone.
These instructions are general information and not specifically for your tractor, but in connection with our
drawings, they might offer your some valuable assistance.
This section covers the installation procedure of an Alamo Group Interstater mower kit, and includes parts lists
for framework, hoses, and miscellaneous parts to be attached to your tractor.
These instructions are for mounting the center mower, right side mower, and left side mower units. For
mounting one mower side only, disregard information concerning the opposite side. Hardware quantities
shown are for both sides.
1. The hydraulic system must be kept “SURGICALLY CLEAN” to ensure proper operation and long life of the
pumps, motors, and valves. All components have protective caps over openings connected to internal
spaces to prevent contamination. It is important that care be taken during unpacking, assembly, and other
contaminants which will damage parts.
2. After the drive belts are installed, DO NOT start the tractor unless the hydraulic system is filled with
ASSEMBLY
hydraulic oil. Running without oil will damage the pumps.
3. Check the oil level in the reservoir before start-up.
4. Care should be taken when filling the reservoir to prevent contamination of the hydraulic system. Always
use new hydraulic fluid when filling the system. USE ONLY TRACTOR HYDRAULIC OIL IN THE
HYDRAULIC SYSTEM.Reference to the left or right side of the Interstater is determined while facing the
front of the tractor from the drivers seat.
Reference to the left or right side of the Interstater is determined while facing the front of the tractor from the
drivers seat.
Assemble the Interstater, step by step, as illustrated on the pages of this section. Small parts (bolts, nuts, etc.)
required are packed in numbered plastic bags which correspond to assembly procedures and illustrations in
the manual.
The part quantities listed for an illustration pertain only to that phase of assembly. The quantity given
corresponds to the number of parts needed. When assembling a single-sided model based on a dual-sided
model, the quantity furnished will usually be half the quantity listed.
Large parts are not always listed next to an illustration because they are usually easy to identify.
Whenever reference is made to parts, listed for an illustration or elsewhere in this manual, the following
abbreviations are used:
HHCS - hex head capscrewRH - right handNF - national fine
LW - lock washerLH - leftMA - mechanical assembly
PW- plain washerNC - national coarseWA - welded assembly
When installing fasteners, PW and LW (generally installed in that order) are usually on the side of the fixture or
part being fastened that the hex/lock nut is on. When only HHCS, LW and/or PW are required, they are
generally installed in that order. Some parts do not require a PW or LW. Refer to illustrations for exceptions.
Fasteners should be installed so they cause the least interference with other parts. When securing driveshaft
pulley to hub, tighten fasteners to 9 lb-ft torque.
This manual makes reference to individual component parts, some of which may have been pre assembled at
the factory.
Depending on the make and model of tractor the INTERSTATER is to be mounted on, certain modifications will
be illustrated. In some cases special accessory components for the tractor will be required before assembling
the INTERSTATER. In these cases, specific mention will be made to the manufacturer, part number and
description of required accessory component.
If so equipped, remove drawbar from rear of tractor. In most cases, the main frame rear pad is attached under
the rear axle.
If so equipped, remove all objects from exterior of cab (lights, hand rails, etc.) which may interfere with mowers
when placed in the transport position. Remove all objects from right front interior of cab structure which may
interfere with mounting and operation of sectional control valve.
If so equipped, remove foot step from each side of tractor to which a mower will be mounted.
Front tractor wheels may require a wider adjustment to clear hydraulic tank and tank mounting frame.

approximately 3” from ignition switch. Using the internal and external bullet connectors provided, install the
“Line-connector” (internal) onto wire at ignition switch which is 3” long. Install the “Bullet-Terminal” (external)
onto the wire leading to starter solenoid.
ASSEMBLY
ELECTRICAL CIRCUIT
Using ASM-FL-20-22 as a guide, install electrical
components and wiring.
Wires from the safety switch must be routed close
to cutter housing sidesheet and lift frame pivot
points. This will prevent wires from being stretched
and broken when cutter housing is raised or
lowered to maximum positions.
NOTE: Route wires in such a manner to prevent
interference with the operation of tractor or
INTERSTATER. Ensure that wires DO NOT lay
against anything which could wear through
insulation and cause a short circuit.
After connecting all wires, wrap wires with
flexguard tubing. Neatly gather hydraulic hoses
and flexguard tubing and strap together using
plastic ties.
NOTE: Be sure to install connector so that larger brown wires are located on bottom poles of switch. This
applies to Dual Wing and Single Wing applications.

Refer the Tractor Manual when connecting hydraulic hoses to the tractor hydraulic system.
Not only does the installation procedure vary from tractor to tractor, but numerous
precautions should be taken due to the possibility of a pressure buildup within the hydraulic
circuit. Relieve the pressure before opening or entering the circuit. FLUID ESCAPING
UNDER PRESSURE CAN PENETRATE THE SKIN CAUSING SERIOUS INJURY. Ensure
that hose fittings are secure before pressurizing the hydraulic systems.
Once pumps and belts are installed, DO NOT start the tractor (which will turn pumps) unless
both power circuits are filled with the specified hydraulic fluid. Running pumps without oil will
cause non-warrantable damage.
It is important that pipe thread sealant be used only on solid connections of pipe thread;
never on connections between swivel fittings and solid male pipe threads or on straight thread "O" ring fittings.
Use the pipe thread sealant supplied. Do not substitute with some other type of sealant, i.e., teflon tape, paint,
shellac, etc.
Hoses supplied have two types of fittings; solid or swivel. Some hoses have solid fittings on both ends; others
ASSEMBLY
have a solid fitting and a swivel fitting. Hoses with two solid fittings will fit into either a female solid thread, or a
swivel adapter union. When installing either type hose, solid fittings must be installed first, then install the
swivel end of the hose.
The INTERSTATER hydraulic system incorporates three basic types of hydraulic fittings:
a. Standard pipe (NPT or NPTF) thread fittings. This type requires a small amount of evenly-applied sealant.
b. Swivel fittings. This type does not require any sealant on the swivel end because it seals against an internal
flare.
c. “O” Ring fittings. This type does not require any sealant on the “O” Ring end of the fitting.
It is extremely important to avoid getting pipe thread sealant inside the fittings or hoses. KEEP THE INTERIOR
OF ALL HYDRAULIC COMPONENTS SURGICALLY CLEAN. Inspect the inside diameter of each hose before
assembly. Ensure that no obstruction is present. Dirt, sand, dust, etc., are abrasive and once in the system can
cause immediate or early failure.
POWER CIRCUIT
Using the following drawing and your installation drawing as a guide to install the hydraulic hoses and fittings
for the power circuit. The power circuit drives the Interstater wing cutter units. The control circuit (for lift and tilt)
will be assembled later.
NOTE: Do not strap hoses together until all hoses and wiring are connected. Hoses and wiring should be
routed so they do not lay on moving parts, too close to sharp edges, or near excessive heat.

motor, and hoses for connecting the
overhauled machine’s hydraulic system.
ASM-FL-0048
After the first 10 hours of operation, replace
the hydraulic filter with a new one. An extra
Filter Element is provided for you. Refer to
the Operation and Maintenance Section for
instruction.
7. After the Interstater mower is completely
assembled to the tractor and with the wings
on the ground, fill the mower hydraulic tank
above the oil level sight gauge approximately 5" or 1" below the top of the tank.
8. With mower ON/OFF switches in “ON” position and tractor fuel cut off, crank engine for about 30 to 45
seconds to allow oil to fill pumps and motors. Check the oil level in the sight gauge. If no oil is seen add oil to
bring the level up to the sight gauge. NOTE:Do not fill the tank with oil above the level of the sight gauge.
Over filling the tank with oil after the initial filling may result in oil being discharged through the air filter on top of
the hydraulic tank. Start the tractor and run it for 2 minutes and then turn it off. Again check the oil level in the
sight gauge. If the oil level is in the sight gauge, the unit is ready to run. If no oil is seen, add oil to bring the
level up to the sight gauge.
Remove all foreign objects and stand clear of cutter units. DO NOT GET NEAR ROTATING
KNIVES!
ASSEMBLY
NOTE: On tractor hydraulic powered circuit only, make certain that there is full flow from tractor hydraulic
system to control valve. Refer to tractor manual.
9. After hydraulic system is fully charged and functioning properly, switch cutter units on, then speed engine up
to 540 RPM PTO speed. Maintain this speed for about 5 minutes. Check complete INTERSTATER, look for
any leaks, loose connections, or anything that could cause premature wear or failure.
FINAL CHECK
Run INTERSTATER for about 1/2 hour at full speed. Check for leaks and vibrations. Frequently check oil
temperature. Make certain it does not exceed 180 deg.
NOTE: When raising wings, make certain there is no interference with mower, frame, cylinders or tractor. Lift
wings slowly.
DO NOT leave unit unattended, and COMPLY WITH ALL WARNING DECALS.
If unit starts to make unusual noise, stop unit and check oil level. Also check for frothy oil which would indicate
a leak on suction side of system.
Before attaching mower to tractor, it will be necessary that each tractor lower hitch arm has freedom of
movement so that the mover is completely independent of tractor movement. This will allow the mower to pivot
sideways as well as move vertically.
Some tractors provide this “float” by means of an optional slot in the lower end of each lift link, others by lift
links which can be made telescopic by changing the position of the pins in the links. Failure to provide “float”
may result in failure of the cutterhousing and bearings in the roller, thus voiding the mover warranty. Should
your tractor not have a built in “float” option, a flexible lift chain assembly will be required.
On all centered mowers, two flexible lift chain assemblies will be necessary to provide “float” to each lift link.
On all offset mowers, one flexible lift chain assembly will be necessary to provide “float” to the lift link on the
same side that the mover is offset. The other lift link should be the adjustable stiff link furnished with the
tractor.
After the mower is attached to the tractor’s 3-point hitch, but before the universal slip joint is installed, and with
the mover on the ground, adjust the top link of the hitch to make the mower gearbox input shaft parallel to the
tractor P.T.O. shaft. This relationship provides optimum operation of the universal joints in the driveline.
Driveline that is not parallel to PTO will result in vibration due to the characteristic of a universal joint that
ASSEMBLY
results in the output end speeding up and slowing down twice each revolution of the universal jointed shaft.
Adjust the top link whenever the cutting height is changed.
1. Tip cutterhousing back and place a block under roller to safely support unit. Remove shipping skids and
drive pulley side belt guard fender. If necessary, install knives, as shown, one row at a time. ALL KNIFE PINS
ARE INSTALLED WITH THEIR HEADS FACING AWAY FROM THE CUTTERSHAFT PULLEY. This will
locate cotter pins where knives cannot reach them when flexing backward. The housing side sheet has a hole
in it which allows knife pins to be inserted into end lugs from outside the cutterhousing. After the cotter pin is
installed, bend extended prong at a 45 Degree angle with prong parallel to lug. ASMP-FL-0047
With the cutterhousing tipped up, attach housing
shoes/wearplate. Carriage bolt attaches to front
mounting hole; plow bolts attach to middle and rear
holes.
1. Attach overarms to cutterhousing. Secure each in 2 places with 5/8 NC x 1-3/4 Hex Head Capscrew(#1),
and nut.
2. Attach “A” frame arms to front of cutterhousing. Secure each, plus overarms in place with 5/8 NC x 2-1/2"
HHCS, and nut(#2).
3. Attach gearbox mounting frame to overarms and A- frame arms. ASM-FL-0049

used as an anchor for the idler arm spring.
REVERSE ROTATION (Bearing plate mounts on right side of cutterhousing)
a. Secure with 3/8 NC x 2-1/4 HHCS, nut and second nut at front mounting hole. The HHCS is used as an
anchor for the idler arm spring.
b. Secure with 3/8 NC x 7/8 HHCS and nut at rear mounting hole.
2. 2. Install gearbox & extension shaft assembly and PTO shield mounting bracket
a. Remove existing nuts and lock washer from bearing housing.
NOTE: On forward rotation units, remove only the lower two fasteners.
b. Slide bearing housing HHCS into proper holes in outboard bearing plate.
ASSEMBLY
c. Attach gearbox and mounting bracket to gearbox mounting frame. Secure with 5/8 NC x 1-1/4 HHCS
(upper gearbox feet), and 5/8 NC x 1-1/2 HHCS (lower gearbox feet) and Lockwashers. Torque to 170 ft-lbs.
(Typ.)
If extension shaft does not line-up with Gearbox, it may be necessary to shim gearbox
mounting lugs. To accomplish this, insert one gearbox retaining bolt (Item 1), ASM-FL-0050 thru the mount plate and into the gearbox housing. Do not tighten this bolt (it should
have at least 1/4" free threads to move in and out). Assemble the gearbox, shaft, shaft
extension tube and the bearing to the bearing retainer plate mounted on the side sheet.
Tighten all fasteners except the one bolt in the gearbox mounting plate. Check the
distance between the gearbox mounting lugs and the mount plate. If required, insert shims
from shim kit (P/N 000552), ASM-FL-0051 between gearbox mounting lugs and mounting
plate to insure the gearbox pulls up evenly on the mounting plate.
1. Properly mount rear mower to tractor and install
driveline. See INSTALLATION AND
DRIVELINE SECTIONS.
2. Attach PTO shield to mounting bracket. Snap-
on shield is positioned so lower ears engage
holes in bracket; upper ears rest on top of
bracket. Bolt-on shield is secured with 3/8 NC x
3/4 HHCS (4 places).
3. Attach belt guard to cutter housing then
reattach belt guard fender.
Belt Guard, FORWARD ROTATION
Three 1/2 NF x 1-1/4 HHCS and nuts.

1/2NF x 1-1/4 HHCS two plain washers, and one
nut. Plain washers are located at upper two belt
guard attaching points
UNIVERSAL SLIP JOINT (PTO SHAFT): Refer to
instructions supplied with shaft.
To install the driveline separates slip joint halves,
then install them onto mower gearbox input shaft
and tractor PTO driveline according to illustration on
PTO shaft shield. Hold halves side by side, then
raise and lower the mower to determine that there
is no interference between halves when in the
shortest position, and that there is a specified
minimum amount of overlap (see PTO SHAFT PARTS LIST section) when in the longest position.
Once it is determined that the shaft will cause no
clearance problems, remove the halves, rejoin them
and install the assembled PTO shaft between the
tractor and the mower.
After attaching PTO shaft, slowly raise and lower
mower to make sure shaft will not make any contact
with “A-Frame” or mower head. If a problem exists,
change mounting position or lengths of lift chains by
removing or adding links.

ALAMO INDUSTRIAL INTERSTATER
OPERATING INSTRUCTIONS
Alamo Industrial Interstater flail mowers are manufactured with quality material by skilled workers. These
mowers are designed for cutting grass and small weeds. The mower is equipped with protective deflectors to
prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective. All
shields, guards, and deflectors equipped on the mower must be maintained in good operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every
reasonable precaution to ensure oneself, others, animals, and property are not injured or damaged by the
mower, tractor, or a thrown object. Do not operate the mower if passersby, pets, livestock, or property are
within 100 yards of the unit.
This section of the Operator’s Manual is designed to familiarize, instruct, and educate safe and proper mower
use to the operator. Pictures contained in this section are intended to be used as a visual aid to assist in
explaining the operation of a Interstater flail mower and are not specific to any model. Some pictures may show
shields removed for picture clarity. NEVER operate implement without all shields in place and in good
operational condition. The operator must be familiar with the mower and tractor and all associated safety
practices before operating the mower and tractor. Proper operation of the mower, as detailed in this manual,
OPERATION
will help ensure years of safe and satisfactory use of the mower.
To avoid mower damage, retorque all bolts after the first 10 hours of operation. Refer to the
Torque Chart at the end of the Maintenance Section to ensure bolts are properly tightened.

Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation
and all associated safety practices. In addition to the safety messages contained in this manual, safety signs
are affixed to the implement and tractor. If any part of the operation and safe use of this equipment is not completely understood, consult an authorized dealer for a complete explanation.
If the operator cannot read the manuals for themselves or does not completely understand the operation of the
equipment, it is the responsibility of the supervisor to read and explain the manuals, safety practices, and
operating instructions to the operator.
Safe operation of equipment requires that the operator wear approved Personal Protective Equipment (PPE)
for the job conditions when attaching, operating, servicing, and repairing the equipment. PPE is designed to
provide operator protection and includes the following safety wear:
PERSONAL PROTECTIVE EQUIPMENT (PPE)
•Always Wear Safety Glasses
•Hard Hat
•Steel Toe Safety Footwear
•Gloves
•Hearing Protection
•Close Fitting Clothing
•Respirator or Filter Mask (depends on operating conditions) OPS-U- 0002
DO NOT use drugs or alcohol immediately before or while operating the
Tractor and Implement. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or Implement,
an operator on prescription or over-the-counter medication must consult
a medical professional regarding any side effects of the medication that
would hinder their ability to operate the Equipment safely. NEVER
knowingly allow anyone to operate this equipment when their alertness or
coordination is impaired. Serious injury or death to the operator or others
could result if the operator is under the influence of drugs or alcohol.
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 models 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 rollover-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)
3.2 Tractor Safety Devices
If transporting or operating the tractor and implement 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 tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
3. 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.
•Tractor Horsepower-Minimum.......... Rear INT 88” 60hp, Rear INT 96” 60hp
•Drawbar............................................ 14” length-measured from end of PTO shaft to hitch pin hole, rated to
carry mower tongue weight, safety chain attachment point
•Hydraulics......................................... 4-Spool Valve & 2-Spool Valve with Detent Position
•Power Take Off................................. 540 RPM
OPERATION
3.3 Tractor Horsepower
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
Rear INT 88” & 96”mowers require a tractor with at least 60HP. Operating the mower with a tractor that does
not have adequate power may damage the tractor engine.
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 disengaged. 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 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 or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are
completelystopped.
(SG-12)
4.1 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.
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 or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are
completelystopped.
(SG-12)
4.2 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, place the transmission in neutral and set 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 lower the implement, set the parking
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.
The operator must have a complete understanding of the placement, function, and operational use of all
tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
Essential Tractor Controls:
•Locate the ignition key/switch
•Locate the engine shut off control
•Locate the hydraulic control levers
•Locate the light control lever
•Locate the brake pedals and clutch
•Locate the PTO control
•Locate the 3 point hitch control lever
•Locate the boom operating controls (joystick or valve bank)
Before starting the tractor ensure the following:
•Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
•Make sure all guards, shields, and other safety devices are securely in place.
•The parking brake is on.
•The tractor transmission levers are in park or neutral.
•The boom operating controls are in the neutral and off position.
•The PTO control lever is disengaged.
•The hydraulic remote control levers are in the neutral position.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-B- 0003
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health.
(SG-23)
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)
6. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at
ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points
between the tractor hitch arms and mower pins. OPS-R-0001
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.
(S3PT-15)
6.2 Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support.
After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain
length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both
directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the
chain around the tongue. Replace the safety chain if one or more links or end fittings are broken, stretched or
otherwise damaged or deformed. OPS-U-0039
6.1 Connecting the Mower A-Frame to the Tractor
1. Make sure the tractor is equipped with the
correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid
interference when raising and lowering the
mower.
3. Board the tractor and start the engine. Position
the tractor to the mower with the 3-point lift
arms positioned between the respective set of
mower A-frame lift lugs. Note: Set the 3-point lift
control to “Position Control” so that the lift arms
maintain a constant height when attaching the
mower. See the tractor Operator’s Manual for
correct settings when attaching 3-point
equipment.
4. Turn off the tractor engine and dismount.
5. One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert hitch
pin through the lug and arm holes and insert
retaining pin into hitch pin.
6. Walk around to opposite side and repeat
procedure for remaining lift arm and hitch pin.
7. Extend or retract 3-point top link to align its end
hole with the holes of the mower’s top link.
Insert the top link hitch pin and insert retaining
pin into hitch pin.
8. Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact
with tractor rear tires.
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make
a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of
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. Always avoid operating the mower at a height
which causes the blades to contact the ground. OPS-U- 0010
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
1. The mower’s cutting height is set by positioning
the roller assembly for each mower section.
Each section must be set at the same height to
ensure an even cut across the entire width of
the mower.
2. Place the tractor and mower on a level surface
and completely lower the mower to the ground.
3. Shut down the tractor, place the transmission in
park, and set the parking brake before
dismounting.
4. One section at a time, place lifting device
(scissors jack or hydraulic jack) under center of
cutter housing.
5. Remove hex nuts, washers and carriage bolts
from bracket at each end of roller. Make certain
that roller bracket is free to move once the
fasteners are removed. A stuck roller could
drop unexpectedly and cause injury.
6. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
7. Lower cutter housing to the ground and remove
lifting device.
8. 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 a even cut across the entire
width of 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 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)
8. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for 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 balls are seated onto the PTO
shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
After the driveline is securely attached, place the
tractor PTO master shield back in the operating
position. OPS-R-0003
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 becomes solid-it can shorten no more. Bottoming 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.
(S3PT-18)
7.2 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.
•Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
•Place a mark on the inner shield 1/8” from the
end of the outer shield and reattach the
driveline to the PTO Shaft.
•With the PTO NOT TURNING, slowly drive the
tractor with mower attached through the
sharpest turn possible and watch shaft
movement. With the PTO NOT TURNING,
slowly drive the tractor with the mower attached
through the most severe terrain conditions
expected and watch shaft movement.
•If the distance between the mark and the outer
shield becomes less than 2” at any point there
is a potential problem bottoming out the
driveline and the driveline should be shortened.
OPS-F-0001
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 12” must be maintained.
•Position the mower to the point with the shortest
distance between the tractor PTO shaft and cutter
gearbox. Shut down the tractor and securely block
the mower in this position.
•Pull driveline apart and reattach yoke to PTO shaft.
•Hold driveline sections parallel to one another and
measure back 1” from yoke of each shaft and place
mark on opposite section. Cut this length off with a
saw.
•Round off all sharp edges and debur.
•Thoroughly grease then reinstall the driveline.
•Recheck for proper operation.
Engagement Check Procedure
•With the driveline attached, position the mower to the
point where the telescoping driveline is at its maximum extension. Completely shut down the tractor and secure in
position.
•Mark the inner driveline shield 1/8” from the end of the outer shield.
•Disconnect the driveline from the tractor and separate the two driveline halves.
•Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles
were engaged.
•If the engaged length is less than 12” the shaft is considered too short and should be replaced with a longer shaft.
Consult an authorized dealer to purchase the required driveline length.
NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made
aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline.
OPS-F-0002
9. PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the implement and tractor must be performed.
This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped
and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection
reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing
parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time
and repair cost can be avoided. OPS-U-0029
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Mower. Never work on the Mower with the tractor PTO driveline connected and
running. Blades or Drivelines could turn without warning and cause immediate
entanglement, injury or death.
(SRM-3)
Always disconnect the main PTO Driveline from the Tractor before performing service on

DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death.
(STI-03)
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order.
(SG-21)
9.1 Tractor Pre-Operation Inspection/Service
Refer to the tractor operator’s manual to ensure a
complete pre-operation inspection and scheduled
service is performed according to the
manufacturers recommendations. The following
are some of the items that require daily service and
inspection:
Before each mower use, a complete inspection and service is required to ensure the mower is in a good and
safe working condition. Damaged and/or broken parts should be repaired and/or replaced immediately. To
ensure the mower is ready for operation, conduct the following. OPS-R-0007
All Safety Shields, Guards and Safety devices including (but not limited
to) - the Deflectors, 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.
(SFL-5)
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY
CAUSE SERIOUS INJURY FROM THROWN BLADES.
(SGM-10)
The operator’s manual and safety signs affixed on
the unit contain important instructions on the safe
and proper use of the equipment. Maintain these
important safety features on the implement in good
condition to ensure the information is available to
the operator at all times.
•Ensure the manual canister is secured to the
equipment with the operator’s manual inside.
•Ensure all safety signs are in place and legible.
Replace missing, damaged, and illegible
decals. OPS-U- 0011
•Check that the main driveline securely
attached to the tractor and the locking collar is
seated in the groove of the PTO Shaft.
•Ensure wing hydraulics are secure at both
ends.
•Ensure the mower hitch is securely attached
to the tractor drawbar with a proper size bolt
and secured nut.
•Ensure that a properly rated safety tow chain
is equipped securing the mower to the tractor.
OPS-F- 0003
•Ensure rubber deflectors are in position and not
damaged. Replace worn, broken, and missing
sections immediately.
•Ensure the rollers are in good condition and
rotate freely.
•Ensure the driveline integral shield is in good
condition and rotate freely.
•Inspect that all bolts and screws are in position
and are properly torqued. OPS-F- 0004
•Inspect the condition of the wings and rear
section drive belts.
•Ensure the slip clutch (rear mower section only)
is properly adjusted and the friction plates are
not frozen together. Reference the
Maintenance Section for proper slip clutch
maintenance.
•Ensure the slip clutch shield and drive belts
shields are in place and in good repair.
•Ensure the tractor PTO master shield is in
place, lowered and in good condition.
•Inspect oil level in gearbox and replenish if
needed. A low oil level is a warning sign that
the gearbox may be cracked or its seal is
damaged and needs to be replaced.
•Check the oil level in tank and replenish if
need. NOTE: Do not fill the tank with oil above
the level of the sight gauge. Over filling the
tank with oil after initial filling may result in oil
being discharged through the air filter on the
top of the hydraulic tank.
•Perform scheduled lubrication as specified in
the maintenance section. OPS-F- 0006
•Inspect cutter knives and knife pins for
looseness and excessive wear. Make sure the
mower is securely blocked up before crawling
beneath. Replace damaged, worn, and missing
knives as complete sets to maintain cuttershaft
balance.
•Remove any grass or other debris which may
be wrapped around the cuttershafts.
•Inspect the condition of deck skid shoes and
hardware. OPS-F- 0007
Before conducting the inspection, make sure the tractor engine is off, all
rotation has stopped and the tractor is in park with the parking brake
engaged. Make sure the mower is resting on the ground or securely blocked
up and all hydraulic pressure has been relieved.

This Inspection Form may be freely duplicated for extra copies.
This Implement may be 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)
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)
10. DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator 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 implement and the tractor operating controls are set for safe transport. To ensure safety while
driving the tractor with an attached implement, review the following. OPS-U- 0012
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
10.2 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.
1. With tractor engine running, place ON/OFF
switch(s) in "OFF" position and wait for
cuttershaft(s) to stop rotating.
2. Pull LIFT control lever rearward until lift frame is
as high as it will go.
3. Pull TILT control lever rearward until bracket on
unit is above support bar on lift cylinder support. If
unit is in the detent “FLOAT”, it will takes some
effort to pull TILT lever from "FLOAT" position.
4. Push LIFT control lever forward enough to lower
unit slowly. Bar on cylinder support must pass
through bracket on unit as shown in Figure 268.
5. Make certain that all control levers are in "HOLD"
position when transporting unit.
OPERATION
NOTE: Lift and Tilt cylinder rods may be adjusted to
provide proper transport bracket to support bar
clearance.
Loosen rod end clamp.
Shorten stroke on LIFT cylinder to raise lift frame.
Lengthen stroke on LIFT cylinder to lower lift frame.
and/or
Shorten stroke on TILT cylinder to move transport
bracket closer to support bar. Lengthen stroke on
TILT cylinder to move transport bracket away from
support bar.
Once sufficient clearance is obtained, tighten rod
end clamp.
The mower’s center of gravity is raised making the
mower more prone to tipping when the wings are in
the raised position. Use extreme caution when
towing the mower in the transport position and
avoid uneven terrain which could upset the mower.
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement or unit may overturn.
(STI-02)
The mower head will start running when lowered if the mower ON/OFF switch is in the ON
position. Make sure the SWITCH is in the OFF positon before lowering mower wing(s).
(SFL-10)
Ensure that ON/OFF switch(es) is (are) in "OFF"
position. With tractor engine running, pull LIFT
control lever rearward until bracket on cutter unit
clears support bar on lift cylinder support. Push
TILT control lever forward until cutter unit is level
with ground. Push LIFT lever forward enough to
slowly lower unit until it touches ground, then push
both levers forward to "FLOAT" position.
OPERATION
OPERATION
NOTE: For best mowing results and longer roller
life, both LIFT and TILT levers should be in
"FLOAT" position while mowing.
It takes some effort to pull TILT lever from "FLOAT"
position because of detent spring.
The mower must be operated with the cutter
sections fully lowered and the hydraulic control
lever in the float detent to ensure the mower
follows the contour of the ground and to prevent
sections from creeping up. NEVER attempt to
raise the mower while the mower is operating.
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)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up.
(SGM-09)
11.1 Engaging and Disengaging the Power Take Off (PTO) and Wings
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be lowered to the mowing position. NEVER engage the PTO with the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position.
To start the wings, make sure they are in the lowered position (refer to Lowering Wings into Operating Position
of the operation section) and PULL the start/stop button(s) to start the wing motor(s) and slowly increase the
engine speed until the PTO is operating at the rated speed. If you hear unusual noises or see or feel abnormal
vibrations, lower the engine RPM’s, disengage the PTO and PUSH the wing start/stop button(s) to stop the
wing motor(s). Inspect the implement to determine the cause of the noise or vibration and repair the
abnormality.
Start off driving at a slow speed and gradually
increase your speed while maintaining complete
control of the tractor and units. Moving slowly at
first will also prevent the tractor from rearing up
and loss of steering control. The tractor should
never be operated 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.
Drive the tractor with the 3-Point lift arms in the
raised position and lock the control lever in the
transport detent position to prevent damage to
the mower driveline and tongue when turning.
Perform turns with the tractor and units at slow
speeds to determine how the tractor with an
attached blade or rake handles a turn. Determine
the safe speed to maintain proper control of the
tractor when making turns. When turning with a
towed implement, the overall working length of
the unit is increased. Allow additional clearance
for the units when turning.
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. Tractor wheel tread spacing
should be increased when working on inclines or
rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep
slopes. Keep the tractor in a low gear when going
When confronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damaged to over collapse of the
driveline may occur.
When crossing such terrain, the implement should
be fully lowered for a lower center of gravity and
added stability. OPS-R-0021
11.3 Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the main driveline
inner profile will penetrate into the outer housing to its
maximum depth until the assembly becomes solid
(driveline is at its extreme shortest length). This type
of abusive operation can cause serious damage to
the tractor and mower drive by pushing the PTO into
the tractor and through the support bearings or
downward onto the PTO shaft, breaking it off.
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing
may allow the driveline to come loose from the Tractor which could cause bodily injury to the
operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
Inclines and ditches should be approached along a
line which is at an angle as shown. This type of
path will reduce the possibility of over-collapse of
the driveline and resulting damage. If the gradient
is so steep that such an approach increases the
possibility of a tractor roll-over, select an alternate
crossing path.
When operating the tractor and mower across
slopes and inclines, through ditches, and other
uneven terrain conditions, it is important to maintain
sufficient deck to ground clearance. Blade contact
with the ground may cause soil, rocks and other
debris to be thrown out from under the mower
resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load
on the mower drive and to the mower blades
resulting in possible damage and premature wear.
OPS-R-0022
12. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
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.
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)
12.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure
there are no foreign objects that the mower blades
could hit or become entangled with. Remove all
foreign objects and debris. If objects are too big to
remove, mark them clearly and be sure to prevent
the mower blades from contacting them.
If you hit a solid object or foreign debris, stop the
mower and tractor at once. Immediately idle the
engine speed and disengage the PTO. Wait for all
mower rotating motion to stop, then raise the
mower and move the tractor and implement off the
object. Inspect the area and remove, or mark the
location of the debris. Inspect the condition of the
mower and make any needed repairs immediately.
Make sure the blades are not damaged and the
carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and
only operate the tractor and mower with the ROPS
in the raised position. If the tractor or mower hits a
tree stump, rock, or bump, a sudden movement
could throw you off of the seat and under the
tractor and/or mower. The seat belt is your best
protection from falling off the tractor and the ROPS
provides protection from being crushed during a
tractor roll-over. OPS-F-0010
12.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,
idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance. OPS-R-0024
Flail 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 300 FEET 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;
-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 wear and tear on the Mower drivetrain, spread cut material better, eliminate
streaking, and make the final cut more uniform.)
(SFL-6)
12.3 PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). 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 PTO and desired ground
speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
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 mower 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-R-0025
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)
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.
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must
be equipped with a ROPS in the raised position or a ROPS cab.
The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and
require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and
maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern
that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the
same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining
the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and
be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to
ensure tractor and mower control is maintained. OPS-R-0026
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 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.
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)
12.5 Shutting Down the Implement
To shut down the implement, first bring the tractor
to a complete stop. Then slow down the implement
by reducing the engine speed before disengaging
the PTO. Push the stop button to disengage the
wings and wait for all motion to stop before
proceeding to drive or shut down the tractor.
Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, lower the attached implement to the
ground, shut down the engine, remove the key, and
wait for all motion to come to a complete stop
before exiting the tractor. OPS-F- 0011
Before disconnecting the mower, the PTO must be
disengaged and all motion at a complete stop.
Move the mower to a level storage location and
lower both wings to the ground. If the mower will
be stored with the sections in the raised position,
be sure that the locks are engaged. If the mower
is not resting securely on the ground, block the
mower up securely before attempting to
disconnect it from the tractor. Use extreme care to
keep feet and hands from under the mower and
clear of any pinch points. OPS-F-0012
After disconnecting the 3 lift points, remove the
mower driveline from the tractor PTO shaft. Lay
the driveline down carefully to avoid damaging
the driveline or its shield. Do not let the driveline
fall into mud or dirt, which can contaminate the
bearing and shorten the life of the driveline.
OPS-F-0013
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
It is recommended that the mower be stored with the center section and both wings fully lowered to ground
level. If the mower is stored with the wings in the raised position, select a level area and install wing transport
braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor.
Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance
and to help ensure years of dependable service. The following are suggested storage procedures:
•Thoroughly clean all debris off the mower to
prevent damage from rotting grass and
standing water.
•Lubricate all mower grease points and fill
gearbox oil levels as detailed in the maintenance section.
•Tighten all bolts and pins to the recommended torque.
•Check the mower for worn and damaged
parts. Perform repairs and make replacements immediately so that the mower will be
ready for use at the start of the next season.
•Store the mower in a clean, dry place with
the mower housing resting securely on
blocks or at ground level.
•Keep the driveline yoke from sitting in water,
dirt and other contaminants.
•Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or
tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid
air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If
the mower has been exposed to such conditions, at the start of each mowing season, and any time it is
suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Clutch Maintenance of the maintenance section in this manual. OPS-F-0014
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Inadvertent contact with controls can cause the
Implement to shift or fall crushing themselves or others.
