5WPMAN0511 (Rev. 2/10/2009)
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 t he operation , transport, maintenanc e
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.
SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information. (Replacement manuals and safety decals are a vailable from
your dealer.) Failure to follow instructions or safety
rules can result in serious injury or death.

Replace if damaged or broken. Check that driveline
guards rotate freely on drive line before putting
equipment into service.
Before starting power unit, check a ll 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 drivelines, repair and replace bearin gs before putting
equipment into service.
Power unit must be equipped with ROPS or
ROPS cab and seat bel t. Keep seat belt secu rely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable

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.
1. Raise mower with tractor hydraulics to 16" at
dimension C or maximum height of tractor lift,
whichever is less.
2. Pivot b oth front caster wheels forward an d check
that there is cle arance bet ween caster wheels an d
tractor tires.
3. If there is interference on models GM1060 and
GM1072, mount front casters in the outer positi on .
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 ca ses. However, you may encounter
areas where the caster wheel s and/or side skids drop
into depressions an d allow center of the mower to contact ground and scalp. An optional front roller may be
installed to minimize scalping. See page 31.
OPERATING TECHNIQUE
Figure 9. Front Caster Wheel Interference Check
Perform this check with all of th e spacers and springs
above the caster wheel arm. This will place the caster
wheels in their high est positi on and provid e the lowes t
cutting height for the mower.

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 s upplied b y tractor PTO.
Operate PTO at 540 rpm. Know how to stop tractor and
mower quickly in an emergenc y.
If mower becomes p lugged causing belt to s lip fo r ov er

1. Maneuver equipment into a previously cut area
and allow mower to clear accumulated material.
Operation 13
2. Continue running at least two minutes, allowing

WARNING
pulleys to cool. Stopping the mow er in con tact with
a very hot pulley will bake and ruin belt.
Uneven Terrain
Proper ground speed will depen d upon the t errain, 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 mater ial 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 cu t 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.
In general, lower cu tting heights give a mo re 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.
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 imp rove your skills in m aneuvering rough
terrain.

Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
Extremely tall material should be cu t twice. Set mo wer
at a higher cutting hei ght for the first pass. Then cut a t
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 procedure. 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.
