GENERAL INFORMATION
Some illustrations in this manual show the
equipment with safety shields removed to provide
a better view. This equipment should never be
operated with any necessary safety shielding
removed.
The purpose of this manual is to assist you in operating
and maintaining your mower. Read it carefully. It fur-
nishes information and instructions that will help you
achieve years of dependable performance. These
instructions have been compiled from extensive field
experience and engineering data. Some information
may be general in nature, due to unknown and varying
operating conditions. However, through experience
and these instructions, you should be able to develop
procedures suitable to your particular situation.
The illustrations and data used in this manual were cur-
rent at the time of printing. However, due to possible
inline production changes, your machine may vary
slightly in detail. We reserve the right to redesign and
change the machines as may be necessary without
notification.
Throughout this manual, references are made to right
and left directions. These are determined by standing
behind the tractor facing the direction of forward travel.

adjusted, and in good operating condition.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Make sure driveline guard tether chains are
attached to the tractor and equipment as shown in
the pamphlet that accompanies the driveline.
Replace if damaged or broken. Check that driveline
guards rotate freely on driveline before putting
equipment into service.
Before starting power unit, check all equipment
driveline guards for damage. Replace any damaged
guards. Make sure all guards rotate freely on all
drivelines. If guards do not rotate freely on drive-
lines, repair and replace bearings before putting
equipment into service.
Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
Remove accumulated debris from this equip-
ment, power unit, and engine to avoid fire hazard.

ing in loss of steering. The weight may be attained
with front wheel weights, ballast in tires or front
tractor weights. Weigh the tractor and equipment.
Do not estimate.
OPERATION
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition.
It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
(Safety Rules continued on next page)
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, concern,
judgement, and proper training of personnel
involved in the operation, transport, maintenance
and storage of equipment.
It has been said “The best safety device is an
informed, careful operator.” We ask you to be that
kind of operator.

and marking requirements.
Never allow riders on power unit or attachment.
MAINTENANCE
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Do not modify or alter or permit anyone else to
modify or alter the equipment or any of its compo-
nents in any way.
Always wear relatively tight and belted clothing

ponents has stopped before approaching for ser-
vice.
Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked and
secured. Never place any part of the body under-
neath equipment or between moveable parts even
when the engine has been turned off. Hydraulic
system leak down, hydraulic system failures,
mechanical failures, or movement of control levers
can cause equipment to drop or rotate unexpect-
edly and cause severe injury or death. Follow Oper-
ator's Manual instructions for working underneath
and blocking requirements or have work done by a
qualified dealer.
Frequently check blades. They should be sharp,
free of nicks and cracks, and securely fastened.

10 Operation
5WPMAN0511 (Rev. 7/18/2008)
OPERATION
The operator is responsible for the safe operation of
the mower. The operator must be properly trained.
Operators should be familiar with the mower, the trac-
tor, and all safety practices before starting operation.
Read the safety rules and safety decals on page 5 to
page 9.
This mower is designed for lawn and grass mowing. It
is not designed for rough conditions or heavy weed
mowing. It is equipped with suction type blades for best
results in lawn mowing.
Recommended mowing speed for most conditions is
from 2 to 5 mph.
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition.
It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Never allow children or untrained persons to
operate equipment.
Keep bystanders away from equipment.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
TRACTOR STABILITY
A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when

CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
NOTICE
■Avoid low cutting heights. Striking the ground
with blades produces one of the most damaging
shock loads a mower can encounter. Allowing
blades to contact ground repeatedly will cause
damage to mower and drive.
1. Level mower from side to side. Check by
measuring from mower frame to the ground at
each deck rail.
2. Verify that the same amount of spacers are under
all caster arms.
3. Loosen cap screws that attach caster arm
assembly to deck.
4. Set mower on the ground.
5. Retighten cap screws. This equalizes the
clearance in the bolt holes.
6. Adjust front of mower level with or slightly lower
than the rear to obtain best mowing results.
7. Control cutting height by adjusting front and rear
caster wheels.
8. To raise rear of mower, move caster adjustment
spacers under rear caster arms. (See Figure 5.)
9. To raise front of mower, move spacers under front
caster wheel arms. (See Figure 5.)

NOTE: The GM1084 front caster arms are fixed and
cannot be changed.
FRONT CASTER WHEEL INTERFERENCE
CHECK
NOTICE
■Do not operate tractor and mower until this
interference check has been performed. If you
change tractors, you must perform the check for
that mounting.
Figure 9. Front Caster Wheel Interference Check
Perform this check with all of the spacers and springs
above the caster wheel arm. This will place the caster
wheels in their highest position and provide the lowest
cutting height for the mower.
1. Raise mower with tractor hydraulics to 16" at
dimension C or maximum height of tractor lift,
whichever is less.
2. Pivot both front caster wheels forward and check
that there is clearance between caster wheels and
tractor tires.
3. If there is interference on models GM1060 and
GM1072, mount front casters in the outer position.
NOTE: On model GM1084, caster wheel width is not
adjustable; see tractor operator's manual and adjust
tractor wheels to narrower spacing.
FRONT ROLLER (OPTIONAL)
The caster wheels and side skids effectively reduce
scalping in most cases. However, you may encounter
areas where the caster wheels and/or side skids drop
into depressions and allow center of the mower to con-
tact ground and scalp. An optional front roller may be
installed to minimize scalping. See page 31.
OPERATING TECHNIQUE
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Power for operating mower is supplied by tractor PTO.
Operate PTO at 540 rpm. Know how to stop tractor and
mower quickly in an emergency.
If mower becomes plugged causing belt to slip for over
two seconds, follow these steps:
1. Maneuver equipment into a previously cut area
and allow mower to clear accumulated material.
CAUTION

14 Operation
5WPMAN0511 (Rev. 7/18/2008)
2. Continue running at least two minutes, allowing
pulleys to cool. Stopping the mower in contact with
a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the
height, and type and density of material to be cut.
Normally, ground speed will range from 2 to 5 mph.
Tall, dense material should be cut at a low speed; thin,
medium-height material can be cut at a faster ground
speed.
Always operate tractor PTO at 540 rpm to maintain
proper blade speed and produce a clean cut.
Under certain conditions, tractor tires may roll some
grass down and prevent it from being cut at the same
height as the surrounding area. When this occurs,
reduce your ground speed, but maintain PTO at 540
rpm. The lower ground speed will permit grass to par-
tially rebound.
In general, lower cutting heights give a more even cut
and leave less tire tracks. However, it is better to cut
grass frequently rather than too short. Short grass
deteriorates rapidly in hot weather and invites weed
growth during growing seasons. Follow local recom-
mendations for the suitable cutting height in your area.
Operating Tips
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
Extremely tall material should be cut twice. Set mower
at a higher cutting height for the first pass. Then cut at
desired height, 90 degrees to the first pass.
Remember, sharp blades produce cleaner cuts and
require less power.
Analyze area to be cut to determine the best proce-
dure. Consider height and type of grass and terrain
type: hilly, level, or rough.
Plan your mowing pattern to travel straight forward
whenever possible. Mow with uncut grass to the right.
This will distribute the clippings over the cut area.
Uneven Terrain
Do not operate or transport on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Use extreme care and reduce ground speed on
slopes and rough terrain.
Watch for hidden hazards on the terrain during
operation.
Pass diagonally through sharp dips and avoid sharp
drops to prevent hanging up tractor and mower.
Practice will improve your skills in maneuvering rough
terrain.

OWNER SERVICE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
Never allow children or untrained persons to
operate equipment.
Keep bystanders away from equipment.
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Operate tractor PTO at 540 RPM. Do not exceed.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
BLOCKING METHOD
Do not work underneath mower unless it is properly
attached to the tractor and blocked securely. When
properly attached, the unit will be anchored to minimize
front to rear movement.
Raise mower completely, set tractor brakes, turn
engine off, remove key, block tractor wheels front and
rear, and disconnect mower driveline from tractor.
The only approved blocking device for this mower is a
jackstand with a load rating of 1000 pounds or more.
One jackstand under each corner of the mower (four
total) must be installed before working underneath.
When blocking, you must consider overall stability of
the unit. Just blocking under the unit will not ensure
your safety. The working surface must be level and
solid to support the loaded weight of the jackstands.
Test jackstand stability before working under any por-
tion of the mower.
Figure 11. Blocking Method
LUBRICATION INFORMATION
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Figure 12 shows the lubrication points. The accompa-
nying chart gives the frequency of lubrication in operat-
ing hours, based on normal operating conditions.
Severe or unusual conditions may require more fre-
quent lubrication. Some reference numbers have more
than one location; be sure you lubricate all locations.
Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulfide) additive for all locations. Be
sure to clean fittings thoroughly before attaching
grease gun. When applied according to the lubrication
chart, one good pump of most guns is sufficient.
Use SAE 80W or 90W gear lube in the gearbox. Fill to
plug on side of gearbox.
Check gearbox daily for evidence of leakage at both
seals and the gasket between the housing and cover. If
leakage is noted, repair immediately. There may be a
small amount of lube emitted from the vent plug; this is
not considered leakage.
Overfilling the gearbox will cause the excess gear lube
to blow out vent plug and ruin the belt.
Driveshaft Lubrication
Lubricate the driveshaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox, and driveshaft.
1. Lower mower to ground.
2. Apply grease at three locations shown in Figure 12.
3. Raise and lower mower several times to distribute
grease.

BELT SERVICE
Belt Replacement
One of the major causes of belt failure is improper
installation. Before installing a new belt, check the fol-
lowing:
1. Check pulley shafts and bearings for wear.
2. Check pulley grooves for cleanliness.
3. Make sure spindles turn freely and without wobble.
If grooves require cleaning, moisten a cloth with a non-
flammable, non-toxic degreasing agent or commercial
detergent and water.
Avoid excessive force during installation. Do not use
tools to pry belt into pulley groove. Do not roll belt over
pulleys to install. This can cause hidden damage and
premature belt failure.
Belt Installation
1. Disconnect idler spring from deck lug I.
2. Slide belt under drive pulley A and over idler arm.
Position belt around drive pulley A.
3. Loosen bolt holding belt guide G and swing it away
from pulley B. Route belt around pulley B, idler C
and pulley D as shown.
4. Make sure belt is on drive pulley A, route around
idler F, and connect idler spring to lug I on deck.
5. Grasp belt between spindle pulley E, spring loaded
idler F and spindle pulley D. Pull spring loaded idler
with belt to obtain enough belt length to route it
over pulley E. Make sure spring-loaded idler pivots
freely with belt installed.
NOTICE
■ Use care when installing or removing belt from
spring-loaded idler at step 5. Springs store energy
when extended and, if released suddenly, can
cause personal injury.
6. Adjust belt guide G to provide 1/16" to 1/8"
clearance from belt. Tighten bolt to 85 lbs-ft.
BLADE SERVICE
Before dismounting power unit or performing
any service or maintenance, follow these steps:
disengage power to equipment, lower the 3-point
hitch and all raised components to the ground,
operate valve levers to release any hydraulic pres-
sure, set parking brake, stop engine, remove key,
and unfasten seat belt.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.

Blade Installation
Your dealer can supply genuine replacement
blades. Substitute blades may not meet original
equipment specifications and may be dangerous.
Figure 14. Blade Assembly
1. Place cap screws (3) through outer holes in blade
and spindle shaft.
2. Make sure blade cutting edge is positioned to lead
in a clockwise rotation, as viewed from top of
mower.
3. Place lock nuts (4) on screws, torque to 84 lbs-ft.
Blade Sharpening
Figure 15. Blade Sharpening
NOTICE
■ When sharpening blades, be sure to balance
them. Unbalanced blades will cause excessive
vibration which can damage blade spindle bear-
ings. Vibration may also cause structural cracks in
mower components.
1. Remove blades.
2. Always sharpen both ends at the same time to
maintain balance.
3. Follow original sharpening pattern.
4. Do not sharpen blade to a razor edge. Leave from
1/32" to 1/16" blunt edge.
5. Do not sharpen back side.
CHAIN SHIELDING
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition.
It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Check that chain shielding is in good condition and
replace any damaged chain links.
CLEANING
After Each Use
●Remove large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
●Inspect machine and replace worn or damaged
parts.
●Replace any safety decals that are missing or not
readable.
Periodically or Before Extended Storage
●Clean large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
●Remove the remainder using a low-pressure water
spray.
1. Be careful when spraying near scratched or torn
safety decals or near edges of decals as water
spray can peel decal off surface.
2. Be careful when spraying near chipped or
scratched paint as water spray can lift paint.
3. If a pressure washer is used, follow the advice
of the pressure washer manufacturer.
●Inspect machine and replace worn or damaged
parts.
●Sand down scratches and the edges of areas of
missing paint and coat with spray paint of matching
color (purchase from your dealer).
