can cause hearing loss through extended
periods of exposure.
Wear hearing protection when operating this
machine.
Thoroughly inspect the area where the
equipment is to be used and remove all
stones, sticks, wires, bones, and other
foreign objects which may damage the
equipment or cause personal injury to
operator or bystanders.
Check that the operator’s presence controls,
safety switches, and shields are attached
and functioning properly. Do Not operate
unless they function properly.
DANGER
In certain conditions gasoline is extremely
flammable and highly explosive.
A fire or explosion from gasoline can burn
you, others and cause property damage.
6
Refuel outdoors, on level ground while
engine is cold.
Never remove fuel cap or add fuel when
engine is running or when engine is hot.
Never fill the fuel tank so that gasoline level
rises above the bottom of the filler neck to
allow for gasoline expansion and prevent
fuel spillage.
If fuel is spilled, DO NOT attempt to start the
engine. Move away from the area of the
spill and avoid creating any source of
ignition until fuel vapors have dissipated.
Do not smoke while refueling and stay away
from an open flame or where gasoline
fumes may be ignited by spark.
Do not operate without entire exhaust
system in place and in proper working
condition.
Do not place any equipment that is leaking
gasoline in an enclosed trailer.
Be sure all fuel tanks and gasoline storage
containers have proper caps installed to
prevent spillage and minimize vapor
escaping into the trailer.
DANGER
In certain conditions during fueling, static
electricity can be released causing gasoline
vapors to ignite.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
Purchase and store gasoline only in an
approved container
Always place gasoline containers on the
ground away from your vehicle while filling.
Do not fill gasoline 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 gas powered
equipment from the truck or trailer and
refuel the equipment with its wheels on the
ground.
If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
Before fueling, touch a metal surface to
minimize the risk of static discharge.
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with rim of the
fuel tank or container opening at all times
until fueling is complete.
WARNING
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors and failure to
use caution may cause serious injury or
illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas
tank/container opening.
Keep away from eyes and skin.
Never siphon by mouth.
OPERATION
Although hazard control and accident
prevention are partially dependent upon the
design and configuration of the equipment,
these factors are also dependent upon the
awareness, concern and proper training of the
personnel involved in the operation, transport,
maintenance and the storage of the equipment.
It is essential that all Operator Safety
Mechanisms be connected and in operating
condition prior to use for mowing.

DRIVING THE MACHINE
TRAINING
Due to unique steering capabilities, zero turn
mowers are far more maneuverable than typical
riding mowers.
This section should be reviewed in its entirety
prior to attempting to move the mower under its
own power. When first operating the mower or
until becoming comfortable with controls, use a
reduced throttle speed and reduced ground
speed. DO NOT move control levers to the
furthest forward or reverse positions during
initial operation.
First time users should become familiar with the
mower’s movement on a hard surface, such as
concrete or blacktop PRIOR to attempting to
operate on turf. Until the operator becomes
comfortable with the mower controls and zero
turning capability, overly aggressive maneuvers
may damage turf.
Use slow and steady movement of the
control levers.
Use caution when making turns.
Slow the machine down before making
sharp turns.
IMPORTANT: To begin movement (forward
or backward) the operator must be in the
seat, the brake lever must be disengaged
(pushed down) before the motion control
levers can be moved in or the engine will
stop.
When the motion control levers are positioned
fully outward (apart) in the T-slot, the drive
system is in the neutral lock position (Figure 13).
When the motion control levers are moved
directly inward (together) the drive system is in
the neutral operate position.
DRIVING FORWARD
1. Release the parking brake.
2. Move motion control levers to neutral
operate position.
3. To move forward in a straight line, move
both levers forward with equal pressure.
To turn left or right, pull the motion control lever
back toward neutral in the desired turn direction.
The machine will move faster the farther the
motion control levers are moved from the
neutral position.
4. To stop, position both motion control levers
in the neutral operate position.
DRIVING IN REVERSE
1. Move the motion control levers to the
neutral operate position.
2. To move rearward in a straight line, slowly
move both levers rearward with equal
pressure.
CAUTION
Erratic movement of the control levers may
cause the Operator to lose control of the
machine, which may cause damage to the
machine or injury.
To turn left or right, release pressure on the
motion control lever toward the desired turn
direction.
3. To stop, position both motion control levers
in the neutral operate position.
19
ADJUSTING THE CUTTING HEIGHT
The cutting height of the mower deck is
adjusted from 1.0 to 5.5 inches (2.5 cm to 14.0
cm) in 1/4 inch (6.4 cm) increments.
1. Stop the machine and move the motion
control levers to the neutral position.
2. Disengage the PTO.
3. Raise and lock the deck to the 5-1/2 inch
(14 cm) transport position.
The deck is raised by pushing the foot
operated deck lift pedal forward. The pedal
is located at the front right corner of the floor
pan.
Note: When changing the cutting height
positions, always come to a complete
stop and disengage the PTO.
4. Stop the engine, remove the key and wait
for all moving parts to stop.
5. Place the rollers in one of the positions
shown. Rollers will maintain 3/4 inch (19
mm) clearance to the ground to minimize
gouging and roller wear or damage.
For cutting heights above 3.5 inches (90 mm)
use the bottom hole. The rollers will still be
effective against scalping.
4. Insert the height adjustment pin into the
hole corresponding to the desired cutting
height.
See the decal on the side of the deck lift
plate for cut heights.
5. Push the deck lift pedal, hold back the
transport pawl handle and allow the deck to
lower to the cutting height.
ADJUSTING THE ANTI-SCALP ROLLERS
It is recommended to change the anti-scalp
roller position, when the height of cut has
changed.
1. Stop the machine and move the motion
control levers outward to the neutral locked
position.
2. Disengage the PTO.
3. Engage the park brake.
For Maximum Deck flotation, place the rollers
one hole position lower. Rollers should
maintain 1/4 (6.4 mm) clearance to the ground.
Do Not adjust the rollers to support the deck.
Note: The foot operated deck lift assist lever
can be used to momentarily lift the deck to clear
objects. Be sure that PTO is disengaged.
20
TRANSPORTING
TRANSPORTING A UNIT
Use a heavy-duty trailer or truck to transport the
machine. Lock brake and block wheels.
Securely fasten the machine to the trailer or
truck with straps, chains, cable, or ropes. Be
sure that the trailer or truck has all necessary
lighting and marking as required by law.
Secure a trailer with a safety chain.
CAUTION
This unit does not have proper turn signals,
lights, reflective markings, or a slow moving
vehicle emblem. Driving on a street or
roadway without such equipment is
dangerous and can lead to accidents
causing personal injury. Driving on a street
or roadway without such equipment may
also be a violation of State laws and the
operator may be subject to traffic tickets
and/or fines.
Do Not drive a unit on a public street or
roadway.
Avoid sudden acceleration while driving
unit forward up a ramp to avoid tipping
backward.
Avoid sudden deceleration while backing
unit down a ramp to avoid tipping
backward.
LOADING A UNIT
Use extreme caution when loading units on
trailers or trucks. Backing unit onto trailer or
truck is recommended practice to avoid
rearward tip-over. However, condition such as
ramp angle and surface slickness can prevent
adequate drive wheel traction to accomplish
this. One full width ramp that is wide enough to
extend beyond the rear tires is recommended
instead of individual ramps for each side of the
unit. The lower rear section of the tractor frame
extends back between the rear wheels and
serves as a stop for tipping backward. Having
a full width ramp provides a surface for the
frame members to contact if the unit starts to tip
backward. If it is not possible to use one full
width ramp, use enough individual ramps to
simulate a full width continuous ramp.
WARNING
Loading a unit on a trailer or truck increases
the possibility of backward tip-over.
Backward tip-over could cause serious
injury or death.
Use extreme caution when operating a
unit on a ramp
Use only a single, full width ramp; Do
Not use individual ramps for each side of
the unit.
If individual ramps must be used, use
enough ramps to create an unbroken
ramp surface wider than the unit.
Do Not exceed a 15 degree angle
between ramp and ground or between
ramp and trailer or truck.
When possible, back machine onto
transport vehicle to avoid a rearward tipover.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp
and the trailer or truck do not exceed 15
degrees. A steeper angle may cause mower
deck components to get caught as the unit
moves from ramp to trailer or truck. Steeper
angles may also cause the unit to tip backward.
If loading on or near a slope, position the trailer
or truck so it is on the down side of the slope
and the ramp extends up the slope. This will
minimize the ramp angle. The trailer or truck
should be as level as possible.
IMPORTANT: Do Not attempt to turn the
unit while on the ramp, you may lose control
and drive off the side.
Avoid sudden acceleration when driving up a
ramp and sudden deceleration when backing
down a ramp. Both maneuvers can cause the
unit to tip backward.

CHECK ENGINE OIL LEVEL
Check the engine oil daily before starting the
engine otherwise shortage of the engine oil may
cause serious damage to the engine such as
seizure.
Allowing batteries to stand for an extended period
of time without recharging them will result in
reduced performance and service life. To preserve
optimum battery performance and life, recharge
batteries in storage when the open circuit voltage
drops to 12.4 volts.
Place the engine on a level surface. Clean
area around the oil gauge before removing it.
Remove the oil gauge and wipe it with a clean
cloth.
Reinsert the oil gauge to check the oil level.
The level should be between “ADD” and “FULL”
marks. Do not overfill.
Install and tighten the oil gauge
NOTE: To prevent damage due to freezing, battery
should be fully charged before putting away for
winter storage.
Check the voltage of the battery with a digital
voltmeter. Locate the voltage reading of the battery
in the table and charge the battery for the
recommended time interval to bring the charge up
to a full charge of 12.6 volts or greater.
CAUTION
Do not fill above the “FULL” mark. Excess oil
will cause a smoking condition, and may cause
the engine to overheat.
CHECK BATTERY CHARGE

HYDRAULIC SYSTEM AIR PURGE
Service Interval: As Required
Due to the effects air has on efficiency in
hydrostatic drive applications, it is critical that
air is removed or purged from the system.
These purge procedures must be preformed
anytime a hydrostatic system has been opened
for maintenance or repair, or if any additional oil
has been added to the system.
Air creates inefficiency because it has
compression and expansion rates that are
higher than that of oil.
Air trapped in the oil may cause the following
symptoms:
Noisy operation.
Lack of power or drive after short-term
operation.
High operation temperature and excessive
expansion of oil.
Before starting make sure the reservoir is at the
proper oil level. If it is not, fill to the vehicle
manufacturer’s specifications.
30
The following procedures should be performed
with the vehicle drive wheels off the ground,
then repeated under normal operating
conditions.
WARNING
POTENTIAL FOR SERIOUS INJURY
Certain procedures required the vehicle
engine to be operated and the vehicle to be
raised off of the ground. To prevent
possible injury to the servicing technician
and/or bystanders, insure the vehicle is
properly secured.
1. With the bypass valve open, (see Drive
Wheel Release in the Operation section)
and the engine running, slowly move the
directional control in both forward and
reverse directions (5 to 6 times). As air is
purged from the unit, the oil level in the
reservoir will drop.
2. With the bypass valve closed and the
engine running, slowly move the directional
control in both forward and reverse
directions (5 to 6 times). Check the oil level,
and add oil as required after stopping
engine.
3. It may be necessary to repeat steps 1 and 2
until all the air is completely purged from the
system. When the drive wheels rotate
forward and reverse at normal speed and
the reservoir oil remains at a constant level,
purging is complete.
THREAD LOCKING ADHESIVES
Thread locking adhesives such as “Loctite 242”
or “Fel-Pro, Pro-lock nut type” are used on the
following fasteners:
1. Clutch retaining bolt in end of engine

due to overheating.
Raising the mower for service or
maintenance relying solely on
mechanical or hydraulic jacks could be
dangerous. The mechanical or hydraulic
jacks may not be enough support or
may malfunction allowing the unit to fall,
which could cause injury.
Do not rely solely on mechanical or
hydraulic jacks for support. Use
adequate jack stands or equivalent
support.

STORAGE
WINTER STORAGE
The machine should be readied for storage at
the end of the mowing season, or if it will not be
in use for more than 30 days.
Fuel allowed to stand for long periods of time
(30 days or more) can leave sticky residues that
can plug the carburetor and disrupt engine
function.
Fuel stabilizers are an acceptable option as
regards to the sticky residues that can occur
during storage.
Add stabilizer to the fuel in the tank or in the
storage container. Always use the mixing
rations specified by the manufacturer of the
stabilizer. Run the engine for at least 10
minutes after adding the stabilizer so that it
reaches the carburetor. Do not empty the fuel
tank and the carburetor if a stabilizer has been
added.
To ready the machine for storage, follow these
steps:
1. Thoroughly clean the machine, especially
under the mower deck. Touch up damage
to the paint and spray a thin layer of oil on
the underside of the mower deck to avoid
corrosion.
2. Inspect the machine for worn or damaged
parts and tighten any nuts or screws that
may have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer.
Start the engine and allow it to run until the
carburetor is drained of fuel or the stabilizer
has reached the carburetor.
5. Remove the spark plug and pour about a
tablespoon of engine oil into the cylinder.
Turn over the engine so that the oil is evenly
distributed and then refit the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. Clean, charge, and
store the battery in a cool place, but protect
it from direct cold.
8. Store the machine in a clean, dry place and
cover it for extra protection.
