5WPMAN0242 (Rev. 7/21/2008)
TRAINING
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 prevention 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.

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 measur-
ing from mower frame to the ground at each deck
rail.
2. Adjust, using tractor 3-point arm leveling device.
NOTE:
front of mower level with or slightly lower than the
rear.
3. Control cutting height with tractor 3-point arms and
front and rear caster wheel adjustment.
4. Raise rear of mower, move caster adjustment
spacers under caster arms. Hex opening of blade
wrench fits bolts on top of caster shaft.
5. Raise front of mower with tractor 3-point arms.
Move spacers under front caster wheel arms.
NOTE:
blade and the ground. The blades are 7-3/4" below
the top of the deck rail on the GM1060 and 8-3/4"
below the top of the deck rail on the GM1072. To
check cutting height, place a straight edge along top
edge of deck rail as shown in Figure 4.
6. Measure from bottom of straight edge to the
ground at locations A and B. Subtract 7-3/4" on
GM1060 (8-3/4" on GM1072) from measurement B
to determine cutting height.
NOTE: Remember, measurement at location A, Figure

FRONT CASTER WHEEL INTERFERENCE
CAUTION
WARNING
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.
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.
Raise mower with tractor hydraulics to 16" at dimension C or maximum height of tractor lift, whichever is
less.
Pivot both front caster wheels forward and check that
there is clearance between caster wheels and tractor
tires. If there is interference, you must not use front
caster wheels on the mower with this tractor.
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.
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.
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 partially rebound.
Figure 7. Front Gauge Wheel Interference Check
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 mower to contact
ground and scalp. An optional front roller may be
installed to minimize scalping.
For Installation instructions See “Front Roller Installation (Optional)” on page 30.
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:
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 recommendations 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.
NOTICE
■ Mower vibration tends to loosen bolts during
operation. All hardware should be checked regularly to maintain proper torque. It is a good practice
to check mower before each operation to ensure all
hardware is secure.
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.
1. Maneuver equipment into a previously cut area and
allow mower to clear accumulated material.
5WPMAN0242 (Rev. 5/2/2008)
Remember, sharp blades produce cleaner cuts and
require less power.

WARNING
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.
2. Collapse driveshaft as far as possible and store it
in PTO hanger bracket to prevent ground contact.
3. Place blocks under mower side skids. Lower
mower onto blocks, disconnect mower from tractor
3-point hitch, and carefully drive tractor away from
mower.

OWNER SERVICE
CAUTION
WARNING
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 information in this manual.
Always wear relatively tight and belted clothing
to avoid entanglement 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.
Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked and
secured. Never place any part of the body underneath 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 unexpectedly and cause severe injury or death. Follow Operator's Manual instructions for working underneath
and blocking requirements or have work done by a
qualified dealer.
BLOCKING METHOD
Jackstands, with a load rating of 1,000 pounds or
more, are the only approved blocking device for this
mower. A minimum of four jackstands, located under
the mower as shown in Figure 9, must be installed
before working underneath this unit. Do not position
jackstands under wheels, axles, or wheel supports
because these components can rotate.
Do not work underneath unless it is properly attached
to tractor (see Operation section), the brakes set, key
removed, and the mower blocked securely. Tighten
tractor lower 3-point arm anti-sway mechanisms to prevent side to side movement.
When blocking, you must consider overall stability of
the unit. Just placing jackstands under the unit will not
ensure your safety. The working surface must be level
and solid to support the weight on the jackstands.
Ensure jackstands are stable both top and bottom, and
mower is approximately level. With full mower weight
lowered on jackstands, test blocking stability before
working underneath mower.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Before working underneath, carefully read Operator’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 hydraulic leak down, hydraulic system failures, or
mechanical component failures.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.

frequent 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.
5WPMAN0242 (Rev. 7/21/2008)
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.
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
Refer to Figure 11.
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.
1. Lower mower to ground.
2. Apply grease at the three locations as shown in
Figure 10.
3. Raise and lower mower several times to distribute
grease.

Belt Replacement
One of the major causes of belt failure is improper
installation. Before installing a new belt, check the following:
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 nonflammable, non-toxic degreasing agent or commercial
detergent and water.
1. Disconnect idler spring from deck lug.
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 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.
6. Adjust belt guide G to provide 1/16" to 1/8" clearance from belt. Tighten bolt to 85 lbs-ft.
