WORK SAFELY - FOLLOW THESE RULES
The designed and tested safety of this
machine depends on it being operated
within the limitations as explained
in this manual. Read manual before
operating.
TRAINING
• Safetyinstructionsareimportant!READTHIS
MANUALANDALLSAFETYRULES.
• Know your controls and how to stop machine,
engine and mower deck quickly in an emer-
gency.
• Toavoidaccidentorinjury,donotallowanyone
to operate this machine without proper instruc-
tion. Any person who operates this machine
MUST be instructed in and capable of the safe
operation of the unit and all controls.
• Do not allow children or unqualified individu-
als to operate machine.
PREPARATION
• Always wear relatively tight and belted
clothing to avoid entanglement in moving
parts. Wear sturdy, rough soled work shoes.
Never operate machine in bare feet, sandals or
sneakers.
• This machine produces sound levels in excess
of 85 dBA at the operator ear and can cause
hearing loss through extended periods of expo-
sure. Wear hearing protection when operating
this machine.
• Walk around machine and visually inspect for
damaged, loose, or missing components. Do
not operate unless all components are properly
mounted, adjusted and in good working condi-
tion.
• Ensure all safety switches function properly.
See Operation section for details.
• Ensure all safety shielding is in good condition
and properly installed.
• Ensure either the discharge shield, restriction
plate, or complete vacuum attachment is in-
stalled.
• Ensure OPS is in good condition and installed
properly. Never modify OPS with holes,
notches or welding. If OPS is damaged, it
must be replaced.
• Check brake action before you operate. Adjust
or service brakes as necessary.
• Ensure all safety decals are installed and in
good condition.
• Remove accumulated debris from machine to
avoid fire hazard.
• Inspectareatobecutremovingstones,branches
and other debris that might be thrown causing
injury or damage.
• Evaluate the terrain to determine what acces-
sories and attachments are needed to properly
and safely perform the job.
• Low-hanging branches and similar obstacles
caninjuretheoperatororinterferewithmowing
operation. Before mowing, identify potential
obstacles such as low-hanging branches, and
trim or remove those obstacles.
• Never permit any person, other than the opera-
tor, to ride or board the mower at any time.
• Operate only in daylight or good artificial light.
FUEL HANDLING SAFETY
• In certain conditions, gasoline, ethanol, die-
sel and other types of fuel are extremely
flammable and highly explosive. A fire or
explosion from fuel can burn you and others
and can damage property.
• Fill the fuel tanks outdoors, in an open area,
when the engine is cold. Wipe up any fuel
that spills.
• Do not remove the fuel cap if the engine or
fuel tank is hot. Allow several minutes to
cool.
• Remove the fuel cap slowly to release any
pressure from the fuel tank.
• Do not fill the fuel tanks completely full.
Add fuel to the tank until the level is .25" to
.5" (6 mm to 13 mm) below the bottom of
the filler neck. This empty space in the tank
allows fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in an approved container and keep
it out of the reach of children. Never buy
more than a 30-day supply of fuel.
• Always place fuel containers on the ground

13
away from your vehicle before filling.
• Do not fill fuel containers inside a vehicle
or on a truck or trailer bed because interior
carpets or plastic truck bed liners
may insulate the container and slow the loss
of any static charge.
• When practical, remove equipment from the
truck or trailer and refuel the equipment with
its wheels on the ground.
• If this is not possible, then refuel such equip-
ment on a truck or trailer from a portable
container, rather than from a fuel dispenser
nozzle.
• Keep the dispenser nozzle in contact with
the rim of the fuel tank or portable container
opening at all times until fueling is com-
plete.
• Never use cellular phones or other portable
electronic devices when handling fuel.
OPERATIONAL SAFETY
• Read “Operation” section of this manual be-
fore attempting to operate this unit.
• This machine is equipped with an Operator
Protective Structure (OPS) and a seat belt.
Do not operate this machine without the
OPS installed and in good condition.
• Always wear the seatbelt.
• Do not operate on slopes greater than 15
degrees (27%).
• To determine the angle of a slope, an angle
measuring device (inclinometer) is readily
available at your local hardware store.
• Fenders serve as shields. Do not operate
without them.
• DO NOT drive machine without mower
deck installed. The proper stability of the
machine depends on the weight of the mow-
er deck.
• Keep bystanders away from equipment
while it is in operation.
• Keep children and pets a safe distance away.
Never direct discharge toward anyone.
• Start engine from operator’s seat after disen-
gaging PTO and placing steering levers into
the swing-out (neutral lock) position.
• Keep hands and feet away from underneath
mower deck while engine is running. Stay
clear of all moving parts on machine.
• Wear suitable hearing protection when oper-
ating this machine.
• Do not operate in reverse unless absolutely
necessary and then only after careful obser-
vation of the entire area behind you.
• If operator must dismount to make adjust-
ments the engine must not be running.
• Do not move steering levers from forward to
reverse or reverse to forward position rapidly.
The sudden direction change could cause loss
of control, especially on slopes.
• Reduce speed on slopes and sharp turns to min-
imize tipping and avoid loss of control.
• The operator is responsible for safe operation
on slopes, even slopes of 15 degrees (27%) or
less. Only the operator can determine the sta-
bility of the mower on a given slope based on
existing conditions like: machine speed and di-
rection, slope variation, slipperiness, drop-offs,
holes, obstacles, etc.
• Stay alert for holes, rocks, roots and other hid-
den hazards in the terrain. Keep away from
drop-offs and soft embankments.
• Stop machine and mower deck immediately
upon striking an obstruction. Turn engine off,
inspect machine and mower deck. Repair any
damage before resuming operation.
• Disengage PTO, stop engine, set park brake,
remove key and wait for all movement to stop
before dismounting, making adjustments,
cleaning, or unclogging the machine.
• Never transport mower with blades running.
Disengage PTO before crossing streets, side-
walks, driveways, etc.
• Watch for traffic when operating near or cross-
ing roadways.
• This machine is not equipped for highway use,
especially when safety lighting and marking is
required. It is not a recreational vehicle.
• This unit is not equipped with a drawbar. Do
not pull loads.
• Take all possible precautions when leaving
machine unattended: disengage PTO, lower
mower deck, place steering levers in neutral,
set parking brake, stop engine and remove key
from ignition.
• Never carry passengers.

14
• Never run engine indoors or in an enclosed
area, unless exhaust gases are safely removed
to the outdoors with an exhaust pipe extension/
hose combination. Exhaust gases contain car-
bon monoxide, an odorless and deadly poison.
MAINTENANCE SAFETY
• Always perform maintenance with the ma-
chine parked on a hard level surface; with
the engine stopped and the PTO disengaged;
with the park brake set; and with the key
removed from the ignition.
• Always remove the grounded (-) clamp from
the battery when performing maintenance
on the engine, clutch, or any other electri-
cal system. The battery is located under the
seat.
• Always wear close fitting clothing and safe-
ty equipment appropriate for the job. Keep
work area clean and dry.
• Never work under the machine without jack
stands or other equivalent safety blocks. Do
NOT rely solely on mechanical or hydraulic
jacks or lifts for support. Always use ad-
equate wheel chocks on tires remaining on
the ground.
• Hydraulic hoses can fail due to physical
damage, kinks, age, and exposure. Check
hoses regularly. Replace damaged hoses.
• Escaping fluid under pressure can penetrate
the skin causing serious injury. Avoid the
hazard by relieving pressure before discon-
necting hydraulic or other lines. Tighten
all connections before applying pressure.
If an accident occurs, see a doctor immedi-
ately. Any fluid injected into the skin must
be surgically removed within a few hours or
gangrene may result.
• Search for leaks with a piece of cardboard.
Protect hands and body from high pressure
fluids.
• Never run engine indoors or in an enclosed
area, unless exhaust gases are safely re-
moved to the outdoors with an exhaust pipe
extension/hose combination. Exhaust gases
contain carbon monoxide, an odorless and
deadly poison.
• Waste products such as used oil, fuel, cool-
ant, and batteries can harm the environment
and people. Dispose of waste products prop-
erly.
• Never attempt to disconnect or alter any part
of the safety interlock systems.
• Do not change engine governor settings.
• Keep engine free of grass, leaves, or excess
grease to reduce fire hazard and minimize
engine overheating.
• Keep machine and mower deck in good op-
erating condition and all safety devices in
place.
• Periodically tighten all bolts, nuts and
screws. Check that all locking pins are prop-
erly installed and in good condition.
• Check brake operation frequently. Adjust
and service as required.
STORING SAFELY
• Never store machine with fuel in the tank
inside a building where fumes may reach
an open flame, spark or pilot light as on a
furnace, water heater, clothes dryer, or other
gas appliance. Allow engine to cool before
storing in an enclosure.
• If engine is to be unused for 30 days or more,
add a fuel stabilizer to the fuel system. Fuel
stabilizer (such as STA.BIL®) is an accept-
able additive in minimizing the formation of
fuel gum deposits during storage.Add stabi-
lizer to fuel in fuel tank or storage container.
Always follow mix ratio found on stabilizer
container. Run engine at least 10 minutes
after adding stabilizer to allow it to reach the
carburetor or injectors.
• If draining fuel tank, drain fuel into an ap-
proved container outdoors and away from
open flame.
• Never run engine indoors or in an enclosed
area, unless exhaust gases are safely re-
moved to the outdoors with an exhaust pipe
extension/hose combination. Exhaust gases
contain carbon monoxide, an odorless and
deadly poison.
• Remove all accumulated debris from mower
deck and tractor.
• Sand areas where paint is chipped and re-
paint to prevent rust. Lubricate all locations
to prevent moisture damage during storage.

OPERATION
The safe operation of this machine is the re-
sponsibility of the operator. Any person who
operates the machine MUST be instructed in
and capable of the safe operation of the machine
and all controls. Read all safety information on
pages 6 through 14.
CONTROLS AND SWITCHES
(Refer to Fig. 3)
Know your controls and how to stop the ma-
chine, engine, and mower deck quickly in an
emergency. Do not operate this machine until
you are completely familiar with the controls
and comfortable with your ability. We recom-
mend you practice in a flat open area at half
throttle until you are comfortable with all the
controls.
The two Steering Levers control speed, motion,
and direction of the machine and are located on
each side of the seat. The left lever controls flow
of hydraulic oil from the left pump to the left
drive wheel motor. The right lever controls flow
of hydraulic oil from the right pump to the right
drive wheel motor. This allows left and right
drive wheels to turn independently, which pro-
vides the “zero turn” ability. Each lever has two
positions: The swung “out” neutral lock posi-
tion, where the lever will not activate the pump;
and the swung “in” operation position, where
the lever will activate the pump. For details of
steering lever operation, refer to the “Steering
Lever Operation” section, page 20-22.
The following controls are located on or beside
the Operator’s Console which is located to the
right side of the seat.
• TheIgnitionSwitch(A) isthekeyswitchlo-
cated on the console. The ignition switch is
used to start and stop the engine. The switch
has three positions OFF, RUN, and START.
Insert the key into the switch and rotate
clockwise to the RUN position. The Brake
Light (B) should be on at this point. Rotate
the switch clockwise to the next (START)
position to engage the engine starter (key
must be held against spring pressure in this
position).
• The Choke Control (C) is the small black
push/pull knob located on the console. The
choke is used to aid in starting a cold en-
gine. Pull the choke knob "up" to activate
the choke on the engine. Push the choke
knob "down" for the choke to be off. DO
NOT run a warm engine with the choke on.
• The Throttle Control (D) is the large black
lever located beside the console to the right
of the seat. The throttle is used to control
engine speed. Move the throttle lever for-
ward to increase engine speed and rearward
to decrease engine speed.
• The PTO switch (E) is the red push/pull
knob located on the console. Pull PTO knob
“up” to engage the electric clutch that drives
the belt connected to the mower deck that
drives the cutting blades. Push the PTO
knob “down” to disengage the electric clutch
that stops the blades from turning within a
few seconds.
• The Hour Meter (F) is the number indica-
tor located on the console. The electric hour
meter is connected to the ignition circuit and
is provided to record the number of hours the
engine runs. If the ignition switch is left on,
without the engine running, the hour meter
will continue to record.
The Park Brake Lever is the lever located on
the left side of the footrest. The brake lever en-
gages compression style parking brakes on the
drive tires. Pull the brake lever up and rearward
until the lever over centers and locks to set the
brakes “on”. Push the brake lever forward and
down to release the brakes “off”.
Several Safety Switches are incorporated in this
machine’s design to prevent the engine from
being started in certain conditions and to kill
the running engine in certain conditions. These
circuits should be checked before each operation
to ensure they are working properly. See page
19 for check list on these circuits.

18
The Start Circuits will keep engine from start-
ing unless:
• Both steering levers are swung out in their
neutral locked position, and
• The PTO switch is down in it’s disengaged
position.
The Kill Circuits will stop the running engine
if:
• The operator raises off the seat any time
during operation of the machine with PTO
engaged or steering levers in operating posi-
tion.
• The steering levers are in their operating po-
sition and the park brake lever is moved into
engaged locked (up) position.
• The park brake is set and the steering levers
are moved into their operating position.
• The operator is off the seat and the steering
levers are moved into their operating posi-
tion.
• The operator is off the seat and the PTO
switch knob is pulled up to its engaged posi-
tion.
Do not operate this machine unless all
safety systems are working properly
as described above.

PRE-START CHECK LIST
Maintain desirable operational standards and
help ensure the safety of the operator by rou-
tinely checking the following on a daily basis:
• Walk around the machine and visually check
for loose or missing components. Make sure
all components are mounted properly and
are in good working condition.
• Make sure all fenders, guards and shields are
safely and securely attached.
• Make sure the discharge shield or restriction
plate is installed at the discharge opening on
the mower deck.
• Make sure all safety decals are clearly read-
able (see page 7).
• Check hydrostatic transmission fluid level.
DO NOT operate machine with low fluid.
Low fluid could cause damage to transmis-
sion and loss of control of the machine.
• Check engine oil level (refer to “Engine
Manual” for proper level and type of oil
used).
Never attempt to check oil while en-
gine is running.
• Check for oil and fuel leaks.
• Clean rotating air intake screen on engine.
When mowing in dusty conditions, dry grass
or long grass, it may be necessary to fre-
quently clean rotating air intake screen to
prevent engine overheating.
Never attempt to clean rotating air
intake screen while engine is running.
• Check air cleaner (refer to “Engine Manu-
al”). When mowing in dusty conditions, dry
grass or long grass, it may be necessary to
frequently clean the foam pre-cleaner and
paper cartridge.

19
• Make sure the engine is free of dirt and de-
bris.
• Check fuel level. Refer to “Engine Manual”
for correct fuel for your requirements.
• For best results, use only clean, fresh, unleaded
gasoline with an octane rating of 87 or higher
((R+M)/2 rating method).
• Do Not use ethanol blends of gasoline (such
as E15 or E85) with more than 10% ethanol
by volume. Performance problems and/or
engine damage may result which may not be
covered under warranty.
• Do Not use gasoline containing methanol.
Do not fill fuel tank while engine is
running. Allow engine to cool several
minutes before adding fuel. If fuel is
spilled, do not start engine and avoid
creating a source of ignition until the
fuel is wiped clean and evaporated.
• Check tire pressure (see page 28). Improper
pressure will adversely affect traction, steer-
ing and level cutting height.
• Check tires for damage or cracking.
• Check hydrostatic pump drive belt for dam-
age or cracking.
• Check mower deck belt for damage or crack-
ing.
• Check mower deck level.
• Check to ensure blades are sharp and se-
cure; the cutting edge should be positioned
in the direction of blade rotation (clockwise
as viewed from top of mower deck).
• Adjust cutting height if necessary.
• Check operation of park brake (see "Park
Brake Adjustment" page 34).
• Remove grass and debris from machine.
• Test safety interlock systems (see chart be-
low). Perform these tests in a clear open
area and keep bystanders away. If there is a
malfunction during one of these procedures,
DO NOT operate machine. (See your Grass-
hopper dealer).

MOUNTING AND DISMOUNTING
THE MOWER
Always mount and dismount the mower from the
left side, with the brake on, the PTO disengaged
(down), the engine off, and the steering levers in
their swung out (neutral lock) position. Mount the
mower by stepping from the ground to the left side
of the deck with your left foot, then step over the
deck carrier frame to the footrest with your right
foot. Anti-skid material is provided on the top of
the deck and footrest. Always keep these surfaces
clean and dry. Replace anti-skid material when
necessary. Wait for all moving parts to stop before
dismounting. Dismount the mower by standing up
onthefootrest, thenturn tothe leftand stepfrom the
footrest, over the deck carrier frame, to the left side
of the deck with your right foot, and then step to the
ground with your left foot. The left steering lever
can be used to stabilize your movement; however,
it is not strong enough to support all your weight.
Never leave the mower unattended with the key in
the ignition.
STARTING THE ENGINE
Never start the engine in confined
rooms. Exhaust gases contain carbon
monoxide, an odorless and deadly poi-
son.
Do not allow children to approach the
machine while the engine is running.
Do not operate the machine around
open flames such as trash fires.
Do not operate the engine when an
odor of fuel is present or other explo-
sive conditions exist.
• Position yourself on the tractor seat.
• Engage the park brake.
• Place both steering levers in swing-out neutral
position.
• Place electric clutch switch in “OFF” (down)
position.
• Set the throttle at 1/3 open.
• Insert the key into the ignition switch and
turn to “RUN” position.
• Check to see that the brake lamp is on.
• Turn the key to “START” position. Choke
as necessary to start. When engine starts,
release key immediately. Push choke knob
down gradually until choke is completely off
and engine is running smoothly.
• Warm the engine up at medium speed for
several minutes.
You will enhance the starter life by using short
starting cycles of several seconds. Engaging
starter motor more than 15 seconds per minute
can result in damage to starter.
COLD WEATHER STARTING TIPS
Use proper viscosity oil for temperature expect-
ed (see “Engine Manual”).
Set throttle at half open.
A warm battery has better starting capacity than
a cold one.
Use fresh winter grade fuel. It is better for win-
ter starting than leftover summer grade fuel.
STEERING LEVER OPERATION
(Refer to page 22, Fig. 4)
Do not move steering levers from for-
ward to reverse or reverse to forward
position rapidly. Sudden direction
changes could cause loss of control or
damage the machine.
Help prevent personal injury. Learn
use of the steering levers and prac-
tice at half throttle until becoming
proficient and comfortable with the
operation of the machine.
