(SGM-11)
WARNING!Do not mount the Tractor while the tractor is moving. Mount the Tractor
only when the Tractor and all moving parts are completely stopped.
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)
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.
Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard. Highpressure oil streams from breaks in the line could penetrate the skin
and cause tissue damage including gangrene. If oil does penetrate
the skin, have the injury treated immediately by a physician
knowledgeable and skilled in this procedure. (SG-15)
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 thrown by the
equipment.(SG-16)
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an
Implement attached can often be noisy enough to cause permanent
hearing loss. We recommend that you always wear hearing
protection if the noise in the Operator’s position exceeds 80db.
Noise over 85db over an extended period of time will cause severe
hearing loss. Noise over 90db adjacent to the Operator over an
extended period of time will cause permanent or total hearing loss.
Note: Hearing loss from loud noise [from tractors, chain saws,
radios, and other such sources close to the ear] is cumulative over a
lifetime without hope of natural recovery.(SG-I7)

following rules:
Test the tractor at a slow speed and increase the speed slowly.
1.
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 safe transport speed for
you and this Equipment.
Test the equipment at a slow speed in turns. Increase the speed
2.
through the turn only after you determine that it is safe to operate
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 safe turning speed for you and this
equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds that you
3.
have determined are safe and which allow you to properly control the
equipment.
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.

(SG-29)
Mow only in conditions where you have clear visibility in daylight or with
adequate artificial lighting. Never mow in darkness or foggy conditions
where you cannot clearly see at least 100 yards 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 this type
of items discontinue mowing.(SGM-1)
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if
shields are not properly installed and maintained. Serious injury or even
death may occur unless care is taken to insure the safety of the
operator, bystanders, or passersby in the area. Do not operate this
machine with anyone in the immediate area. Stop mowing if anyone is
within 100 yards of mower. (SGM-2)

SAFETY
DANGER!
DANGER!
WARNING!
All Safety Shields, Guards and Safety devices including
(but not limited to) - the Deflectors, Chain Guards, Steel
Guards, Gearbox Shields, PTO integral shields , and
Retractable Door Shields should be used and maintained in good working condition. All safety devices
should be inspected carefully at least daily for missing
or broken components. Missing, broken, or worn items
must be replaced at once to reduce the possibility of
injury or death from thrown objects, entanglement, or
blade contact. (SGM-3)
The rotating parts of this machine have been designed and tested for
rugged use. However, the blades could fail upon impact with heavy,
solid objects such as metal guard rails and concrete structures. Such
impact could cause the broken objects to be thrown outward at very
high velocities. To reduce the possibility of property damage, serious
injury, or even death, never allow the cutting blades to contact such
obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by
the operator. Stop mowing immediately if blades strike a foreign
object. Repair all damage and make certain rotor or blade carrier is
balanced before resuming mowing. (SGM-5)
SAFETY
SAFETY
WARNING!
WARNING!
WARNING!
WARNING!
Many varied objects, such as wire, cable, rope, or chains, can become
entangled in the operating parts of the mower head. These items could
then swing outside the housing at greater velocities than the blades. Such
a situation is extremely hazardous and could result in serious injury or
even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to
contact such items. (SGM-6)
Mow at the speed that you can safely operate and control the tractor and
mower. Safe mowing speed depends on terrain condition and grass type,
density, and height of cut. Normal ground speed range is from 0 to 5 mph.
Use slow mowing speeds when operating on or near steep slopes,
ditches, drop-offs, overhead obstructions, power lines, or when debris and
foreign objects are to be avoided. (SGM-7)
Avoid mowing in reverse direction when possible. Check to make sure
there are no persons behind the mower and use extreme care when
mowing in reverse. Mow only at a slow ground speed where you can safely
operate and control the tractor and mower. Never mow an area that you
have not inspected and removed debris or foreign material. (SGM-8)
Do not put hands or feet under mower decks. Blade Contact can result
serious injury or even death. Stay away until all motion has stopped and
the decks are securely blocked up. (SGM-9)
Replace bent or broken blade with new blades. NEVER ATTEMPT TO
STRAIGHTEN OR WELD ON BLADES SINCE THIS WILL LIKELY
CRACK OR OTHERWISE DAMAGE THE BLADE WITH
SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES. (SGM-10)
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-7)
Rotary Mowers are capable under adverse
conditions of throwing objects for great distances
(100 yards or more) and causing serious injury or
death. Follow safety messages carefully
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, or Chain Guards, or Bands are installed
and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the
ground without exposed Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material
such as rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris
that could be struck by the blades, the area should be: inspected
and large debris removed, mowed at an intermediate height, inspected closely with any remaining debris being removed, and mowed
again at desired final height. (This will also reduce power requiredto
mow, reduce wear and tear on the Mower drivetrain, spread cut
material better, eliminate streaking, and make the final cut more
uniform.) (SRM-1)
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 tipover. Slow down on rough or uneven surfaces to prevent loss of
steering control which could result in property damage or possible injury.
Do not transport unless 3-Point lift lever is fully raised and in the latched
transport position. Dropping implement in transport can cause serious
damage to the tractor and/or Implement and possibly cause the operator
or others to be injured or killed. (S3PT-2)
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.

INTRODUCTION
INTRODUCTION
Your FM84A mower is designed for light-duty cutting such as lawn maintenance plus small weed and grass
control. With a reasonable amount of preventive maintenance, your Mower will provide years of dependable
service.
DANGER
NEVER ALLOW CHILDREN TO OPERATE, RIDE ON, OR COME CLOSE
TO MOWER OR TRACTOR. Usually, 15-16 year-old children who are mature
and responsible can operate the mower with reasonable safety if they have
read Operator's Manual, been trained in safe operation of the machine, and
are physically large and strong enough to reach and operate controls easily.
DANGER
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the
use of Chain Guards, Deflectors, or Solid Skirts at all times. The Mower
manufacturer strongly recommends the use of Chain Guards or Solid Skirts for
Agricultural purposes as well, to reduce the risk of property damage, serious
bodily injury, or even death from objects thrown out by or from contact with the
Cutting Blades.
WARNING
At least 20% of the tractor’s weight must be on the front tires with the Mower

OPERATION
2. TRACTOR REQUIREMENTS
The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off
(PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the mower
with a tractor that does not meet the following requirements may cause tractor or mower damage and be a
potential danger to the operator and passersby .
Tractor Requirements and Capabilities
¾ASAE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.
¾3-Point Hitch- ..…………...............................…........... CAT I, Floating Hitch
¾Front End Weights..…………...............................…..... As needed to maintain 20% weight on front axle
¾Power Take Off.........……….........................................540 RPM 6-spline 1-3/8” diameter output shaft
2.1 ROPS and Seat Belt
A Roll-Over-Protective-Structure (ROPS) and seat belt are essential to protect the operator from falling off the
tractor, especially during a roll over where the driver could be crushed and killed. The ROPS and seat belt must be
used in conjunction with one another. 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 tractor dealer.
WARNING!
Operate this Equipment only with a Tractor equipped with an approved roll-overprotective 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)
OPERATION
2.2 Tractor Safety Devices
If transporting or operating the tractor and mower near a public roadway , the tractor must be equipped with proper
warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the unit. Lights
and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning signals are
obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or mower. Never operate the tractor PT O with the
PTO master shield missing or in the raised position.
The horsepower required to operate the mower depends on many factors including the vegetation to be cut, terrain
condition, operator experience, and condition of the mower and tractor. For most mowing condition, the FM84A
mower requires a tractor with at least 30HP. Operating the mower with a tractor that does not have adequate
power may damage the tractor engine.
2.4 Tractor 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
815 lbs. if attaching a FM84A.
This mower is designed to be mounted on tractors with
a CAT I hitch. Refer to the tractor operator’s manual
for the category of the tractor being used. If the hitch
does not conform to ASAE CA T I dimensions, the mower
may not fit or raise properly. Consult an authorized
dealer for possible modification procedures to mount
non-conforming hitches.
Upper Pin Location
Top Link Attaches Here
Use the correct hitch pins for the hitch category being
used. For a Cat I hitch, 7/8” lower and 3/4” upper
diameter hitch pins.
CA T I Implement / Hitch S pecifications
Width from outside to outside A-frame..............26-7/8"
Quick Hitch width inside lug to lug...................27-1/8"
Height from bottom hitch pin to top pin.......................18"
A minimum of 20% total tractor weight must be maintained on the tractor front end when the mower is in the raised
position. Proper weight on the tractor front end is critical to maintain steering control and to prevent the tractor
from rearing up while driving. If the tractor front end is too light, add weight until a minimum of 20% total weight is
reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor
dealership.
2.6 Power Take Off (PTO)
The mower is designed to operate at a PTO speed of 540 RPM. Most tractors operate at either 540, or a
combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined
by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 6spline shaft and those operating at 1000 RPM will have a 21-spline shaft. Refer to the tractor owner’s manual for
instructions to change PTO speeds on models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an overrunning clutch must be used between the PTO output shaft and the driveline of the mower . An authorized tractor
dealer can provide the over-running clutch and its installation if needed.
WARNING!
OPERATION
WARNING!
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 Mower resulting in excessive
vibration, thrown objects, and blade and mower 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 Mower main driveline is directly connected to
the Tractor transmission. T ractor braking dist ances can be substantially increased by the
momentum of the rotating Mower blades driving the T ractor transmission even though the
Tractor clutch has been engaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
Before getting onto the tractor, the operator must read and completely understand the mower and tractor operator
manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete
explanation.
WARNING!
Do Not mount or dismount the Tractor while the Tractor is moving.
The Tractor engine must be turned off, the Tractor transmission in
park or neutral with the parking brake set, and all moving Tractor
and Implement parts at a complete stop before boarding or exiting
the Tractor.
3.1 Boarding the Tractor

¾ Locate the hydraulic remote control lever
Before starting the tractor ensure the following:
¾ Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
¾ All guards, shields, and other safety devices are securely in place.
¾ The parking brake is on.
OPERATION
¾ The PTO control lever is disengaged.
¾ The 3-point hitch control lever is in the lowered position.
¾ The hydraulic remote control levers are in the neutral position.
¾ The tractor transmission levers are in park or neutral.
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 .
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement.
DANGER!
Start the Tractor only when properly seated in the Tractor seat. Starting
a Tractor in gear can result in injury or death. Read the Tractor
operator’s manual for proper starting instructions. (SG-13)
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 out from under the mower deck and clear of pinch points between
the tractor hitch arms and mower pins.
DANGER!
Never stand or allow another person to stand between a running Tractor and the Mower
when attaching the Implement to the Tractor. Always shut the Tractor completely off
before attempting to connect the Mower pins to the Tractor hitch.
5.1 Connecting the Mower
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 at the same height and to the outside
of the mower hitch pins. 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, set the parking brake,
place the tractor in park, and dismount.
OPERATION
5. One lift arm at a time, position the tractor lift arms
over the A-frame hitch pins. Insert linch pins to
retain lift arms to the mower. Walk around to
opposite side and repeat procedure for remaining
lift arm and hitch pin.
7. Extend or retract the 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 mower 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: A void 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.
6.1 Setting Mowing Height-Lift Type
1. Park the tractor and mower on level ground.
2. Using the 3-point hitch control lever, position the
front of the mower with its side skids 1” less off the
ground than desired cut height. For example, for a
3” cut, position the skids 2” from the ground. Set
the 3-point control lever stop at this position to
maintain this height when raising and lowering the
mower.
3. Shut down the tractor and remove the key .
4. Level the mower deck front to rear by extending or
retracting the 3-point top link.
5. Level the mower side to side by manipulating one
lower lift arm length. On most tractors, at least
one of the lift arms is designed to allow for
manipulation of its length. Shortening or extending
will allow for deck leveling from side to side.
6. Securely block up the mower at this height.
7. Holding wheel and yoke assembly up, remove
OPERATION
quick-lock pin from the top of guage wheel spindle.
Position full length spacers and half spacer as
required. All spacers on top of spindle tube allows
for approximately 1” cutting height. Adjustment
range from 1” to a maximum of 4-1/2” in 1/2”
increments.
8. Extend the tractor’s top 3-point link so that when
lifting the mower, the front of the deck will raise 2
to 2½" before the rear guage wheels leave the
ground. This will allow the flexible hitch to pivot
and follow the contour of uneven terrain.
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-9)
7. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
T o 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.
WARNING!
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the
groove of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could
slip off and result in personal injury and damage to the cutter.
OPERATION
DANGER!
Make sure the PTO shield is installed when using PTO-driven equipment.
Always replace the PTO shield if it is damaged or missing. (S3PT-8)
7.1 Driveline Length Modification
WARNING!
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.
Before operating the Mower, check to make sure the 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 PT O by pushing the PTO into the T ractor and through
the support bearings or downward onto the PTO shaft, breaking it off.
Operation Section 4-13
OPERATION
“Bottoming Out” Check Procedure
1. Disconnect driveline from the tractor and slide the
profiles together until fully compressed.
2. Place a mark on the inner shield 1/8” from the
end of the outer shield.
3. Reattach the driveline to the PTO shaft.
4. Lift and Semi-Mount T ype-Raise the mower/ Pull
Type-Turn sharply and watch the driveline as it
approaches the mark. If the distance between the
mark and the outer shield becomes less than 2” at
any point, the driveline must be shortened.
Shorten the driveline profiles as follows:
1. Remove the driveline from the tractor.
2. Position the mower (Lift and Semi-Mount Typeraise and lower/Pull T ype-turn sharply) 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.
3. Pull driveline apart and reattach yoke to PTO shaft.
4. 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.
5. Round off all sharp edges and debur .
6. Thoroughly grease then reinstall the driveline.
7. Recheck for proper operation.
Driveline in maximum compressed position.
OPERATION
Engagement Check Procedure
1.With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum
extension. Turn off the tractor and securely block the mower at this position.
2.Mark the inner shield 1/8” from the end of the outer shield.
3.Disconnect the driveline from the tractor and separate the two driveline halves.
4.Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline
profiles were engaged.
5.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: When raising the mower, at least 1” clearance must be maintained between the driveline and the mower
deck. If necessary , place an upper lift stop on the 3-point hitch control lever to limit the height the mower can be
raised.
Before each use, a pre-operation inspection and service of the mower 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 mower and tractor 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.
DANGER!
WARNING!
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)
OPERATION
Never work under the Mower, the framework, or any lif ted component
unless the Mower is securely supported or blocked up to prevent
sudden or inadvertent falling which could cause serious injury or
Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or
broken parts, and leaking or loose fittings. Make sure all pins have cotter

determined are safe and which allow proper control of the equipment.
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. (SG-19)
OPERATION
9.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is unclear .
Ensure the 3-point control lever is in the lowered position
and the PTO lever is off before starting the tractor .
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 MOWING
CONDITIONS, THE BRAKE PEDALS SHOULD BE
LOCKED TOGETHER TO PROVIDE THE MOST
EFFECTIVE BRAKING ACTION.
WARNING!
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.
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.
OPERATION
9.3 Raising the Mower
Using the tractor 3-point hitch control lever-lift type or
hydraulic remote lever-pull and semi-mount type, raise
the mower high enough to clear all ground obstacles.
When raising the mower, make sure all connection
points are securely attached and at least 1” clearance
is maintained between the driveline and the deck. If
necessary , place an upper lift stop on the 3-point hitch
control lever to limit the height the mower can be raised
to avoid driveline damage.
St art off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor
and mower. 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. If the tractor becomes stuck or the tires are frozen to the ground, reverse
the tractor out to prevent overturning.
Perform turns with the tractor and mower at slow speeds
to determine how the tractor with the mower handles a
turn. Determine the safe operating speed to maintain
proper control of the tractor when making turns. When
turning with an attached rear implement, the overall
length of the working unit is greatly increased. Allow
additional clearance for the mower to swing when
turning.
WARNING!
WARNING!
OPERATION
Be particularly careful when transporting the Mower 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 if necessary, to maintain at least 20% of the Tractor’s
weight on the front wheels to prevent Tractor rearing up, loss of steering control, and
possible 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
the Mower unless the Tractor 3-Point lift lever is fully raised and in the latched transport
position. Dropping the Mower during transport can cause serious damage to the Tractor
and/or Mower, and possibly cause the operator or others to be injured or killed. (S3PT-2)
Mow at the speed that you can safely operate and control the tractor and mower. Safe mowing
speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed
range is from 0 to 5 mph. Use slow mowing speeds when operating on or near steep slopes, ditches,
drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided.
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 downhill.
DO NOT coast or free-wheel downhill.
9.5 Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the 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 may result in damage to the tractor and mower
components in the form of severe catastrophic failures.
WARNING!
When confronted with an incline or ditch, do not
OPERATION
approach from an angle which is perpendicular or straight
on as damage to over collapse of the driveline may
occur.
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 as approach increases the possibility of a tractor
roll-over, select an alternate crossing path.
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
Before starting any mowing operation, the operator must become familiar with the area to be mowed 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.
DANGER!
WARNING!
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 the blade carrier is balanced
before resuming mowing. (SGM-5)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating
parts of the mower head. These items could then swing outside the housing at greater velocities
than the blades. Such a situation is extremely hazardous and could result in serious injury or even
death. Inspect the cutting area for such objects before mowing. Remove any like object from the
site. Never allow the cutting blades to contact such items. (SGM-6)
OPERATION
10.1 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.
10.2 Bystander/Passersby Precautions
If a bystander comes within 100 yards 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 100
yard distance.
DANGER!
OPERATION
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general
debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the
area should be: inspected and large debris removed, mowed at an intermediate height, inspected closely
with any remaining debris being removed, and mowed again at the 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.)(SRM-1)
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (100 yards or more) and causing serious
injury or death. Follow safety messages carefully.
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. Set the tractor
engine speed at approximately 540 RPM before engaging the PTO. Shift the PTO control to the on position, 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, disengage the PTO immediately . Inspect the mower to determine the cause of the
noise or vibration and repair the abnormality
.
DANGER!
DANGER!
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-7)
Do not put hands or feet under Mower decks. Blade contact can result
in serious injury or even death.(SGM-9)
10.4 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. Operate the mower at its full rated 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 the blades make contact with vegetation. If it becomes necessary to
temporarily regulate engine speed, increase or decrease the throttle gradually .
OPERATION
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.
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)
Operation Section 4-25
OPERATION
WARNING!
Mow at the speed that you can safely operate and control the Tractor and Mower. Safe
mowing speed depends on terrain condition and grass type, density, and height of cut.
Normal ground speed range is from 2 to 5 mph. Use slow mowing speeds when operating
on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when
debris and foreign objects are to be avoided. (SGM-7)
10.5 Operating the Mower
The mower is designed to cut grass and small weeds. 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 and
to produce a clean cut. Choose a driving pattern that provides the maximum pass length and minimizes turning.
Remember, sharp blades produce cleaner cut s and use less power.
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 control is
maintained of the tractor and cutter .
DANGER!
OPERATION
DANGER!
WARNING!
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards 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 this type of item 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 in the reverse direction that you have not inspected and removed
debris or foreign material. (SGM-8)
Follow these guidelines to reduce the risk of equipment and grass
fires while operating, servicing, and repairing the Mower and
Tractor:
-Equip the Tractor with a fire extinguisher in an accessible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-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)
