CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
• Keep children out of the mowing area and under the
watchful care of another responsible adult.
• Be alert and turn unit off if children enter the area.
• Before and during reverse operation, look behind and
down for small children.
• Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
• Never allow children to operate the unit.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
• Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
• Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
IGNITION SYSTEM
• This spark ignition system complies with Canadian
standard ICES-002.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not operate
on it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
of the ground conditions, incorrect hitching and load distribution.
• Mow across slopes, not up and down.
• Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
• Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
• Do not mow on wet grass. Tires may loose traction.
• Never mow down slopes.
• Avoid starting, stopping, or turning on a slope. If tires
lose traction (i.e. machine stops forward motion on a
slope), disengage the blade(s) (PTO) and drive slow
off the slope.
• Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
• Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
• Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
• Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an edge
caves in.
• Do not use grass catchers on steep slopes.
• Do not mow slopes if you cannot back up them.
• See your authorized dealer/retailer for recommendations of wheel weights or counterweights to improve
stability.
• Remove obstacles such as rocks, tree limbs, etc.
• Use slow speed. Tires may lose traction on slopes
even through the brakes are functioning properly.
• Do not turn on slopes unless necessary, and then,
turn slowly and gradually uphill, if possible. Never
mow down slopes.
TOWED EQUIPMENT (RIDE-ON UNITS)
• Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
• Follow the manufacturer’s recommendations for
weight limit for towed equipment and towing on
slopes. See attaching a trailer under OPERATION.
• Never allow children or others in or on towed equipment.
• On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
• Travel slowly and allow extra distance to stop.
• Do not shift to neutral and coast down hill.
WARNING
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rearmounted grass catchers.
Mow across the face of slopes, not up and down,use
caution when changing directions and DO NOT
START OR STOP ON SLOPE.
Not for
Reproduction
WARNING: To avoid serious injury, operate your unit up and
down the face of slopes, never across the face. Do not operate
on slopes greater than 10 degrees. Make turns gradually to
prevent tipping or loss of control. Exercise extreme caution
when changing direction on slopes. Braking may be affected by
attachments. Reduce speed on slopes.
1. Fold this page along dotted line indicated above.
2. Hold page before you so that its left edge is vertically parallel to a tree
trunk or other upright structure.
3. Sight across the fold in the direction of hill slope you want to measure.

SERVICE AND MAINTENANCE
Safe Handling of Gasoline
• Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
• Use only approved gasoline containers.
• Never remove the gas cap or add fuel with the engine
running. Allow the engine to cool before refueling.
• Never fuel the machine indoors.
• Never store the machine or fuel container where there
is an open flame, spark, or pilot light such as near a
water heater or other appliance.
• Never fill containers inside a vehicle or on a truck bed
with a plastic bed liner. Always place containers on
the ground away from your vehicle before filling.
• Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dispenser nozzle.
• Keep nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
• If fuel is spilled on clothing, change clothing immediately.
• Never over-fill the fuel tank. Replace gas cap and
tighten securely.
• Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
• If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors
have dissipated.
• Replace all fuel tank caps and fuel container caps
securely.
Service & Maintenance
• Never run the unit in an enclosed area where carbon
monoxide fumes may collect.
• Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.

hydro pump cooling fan, when the tractor is running.
(Hydro pump cooling fans are typically located on top
of the transaxle).
• Units with hydraulic pumps, hoses, or motors: WARNING: Hydraulic fluid escaping under pressure may
have sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected into the skin it
must be surgically removed within a few hours by a
doctor familiar with this form of injury or gangrene
may result. Keep body and hands away from pin
holes or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, and not hands, to
search for leaks. Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines
are in good condition before applying pressure to the
system. If leaks occur, have the unit serviced immediately by your authorized dealer.
• WARNING: Stored energy device. Improper release
of springs can result in serious personal injury.
Springs should be removed by an authorized technician.
• Models equipped with an engine radiator: WARNING:
Stored energy device. To prevent serious bodily injury
from hot coolant or steam blow-out, never attempt to
remove the radiator cap while the engine is running.

OPERATION
Ground Speed Levers
These levers control the ground speed of the rider. The
left lever controls the left rear drive wheel and the right
lever controls the right rear drive wheel.
Pushing the levers out to the side, away from the operator’s lap (top inset, Figure 4), is the proper position for
starting the rider. Pulling the levers in across the operator’s lap puts the levers in DRIVE positions.
From DRIVE position, moving a lever forward increases
the FORWARD speed of the associated wheel. Pulling
back on a lever increases the REVERSE speed. The further a lever is pushed, the faster the drive wheel will turn.
See DRIVING PRACTICE for steering instructions.
Parking Brake Lever
Move the parking brake lever (bottom inset, Figure 4) up
and across and into the locking notch to engage and lock
the parking brake. Move the parking brake lever across
and down to disengage the parking brake. The engine
will not start unless the parking brake is engaged.
NOTE: The parking brake must be disengaged before
operating the ground speed levers.

WARNING
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm)
vertically in 20 feet (607 cm) horizontally.
Select slow ground speed before driving onto a
slope. Use extra caution when operating on
slopes with a rear-mounted grass catcher.
Mow across the face of slopes, not up and down.
Use caution when changing directions and DO
NOT START OR STOP ON A SLOPE.
Do not load this zero-turn rider on a trailer or
truck using two separate ramps. Only use a single
ramp that is at least one foot wider than the width
of the rear wheels of this rider. This rider has a
zero turning radius and the wheels could fall off
the ramps, or the rider could tip over injuring the
operator or bystanders.
WARNING - TRAILERS
CHECKS BEFORE STARTING
• Check that the crankcase oil is filled to full mark on
dipstick.
• Fill the fuel tank with fresh fuel.
FUEL RECOMMENDATIONS
For daily operation: Use only unleaded gasoline with a
pump sticker octane rating of 87 or higher. Gasohol (up
to 10% ethyl alcohol, 90% unleaded gasoline by volume)
is approved as a fuel. Methyl Teriary Butyl Ether (MTBE)
and unleaded gasoline blends (up to a maximum of 15%
MTBE by volume) are approved as a fuel. No other gasoline/alcohol or gasoline/ether blends are approved. Do
not use fuel additives other than fuel stabilizer.
For storage: CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage.
To avoid engine problems always use fuel stabilizer,
especially before storage of 30 days or longer. Use fresh
fuel next season. See STORAGE instructions for additional information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur. To add fuel:
1. Remove the fuel cap (B, Figure 5).
2. Fill the tank. Do not overfill. Leave room in the tank for
fuel expansion.
3. Install and hand tighten the fuel cap.

DRIVING PRACTICE -
BASIC DRIVING
WARNING: Never operate on slopes greater than 17.6%
(10°). See SLOPE OPERATION in the safety section.
Zero turn riders operate differently from other fourwheeled vehicles. The drive wheels are also your steering wheels. If you cannot drive the unit on a hill, you will
not be able to steer the unit on it. Operating zero turn
units on slopes requires extra caution.
The lever controls of the zero turn rider are very responsive, and learning to gain a smooth and efficient control
of the rider’s forward, reverse, and turning movements
will take some practice.
Spend some time going through the following maneuvers
and becoming familiar with how the unit accelerates,
travels, and steers - before you begin mowing - is
absolutely essential to getting the most out of the zero
turn rider.
Locate a smooth, flat area of your lawn - one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit
at mid-throttle during this practice session (ALWAYS
operate at full throttle when mowing), and turn slowly to
prevent tire slippage and damage to your lawn.
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
Forward Travel Practice
Gradually move both ground speed control levers evenly
FORWARD from neutral (see Figure 8). Slow down and
repeat.
Reverse Travel Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral
(see Figure 9). Slow down and repeat.
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice.
Figure 8. Forward Travel
Forward Travel
Figure 9. Reverse Travel
Reverse Travel
Smooth Travel
The lever controls of the
zero turn rider are
highly responsive.
The BEST method of
handling the ground
speed control levers is in
three steps - as shown
in Figure 7.
FIRST place your hands
onto the levers as
shown.
SECOND, to go forward
gradually push the levers
forward with your palms.
THIRD, to speed up
move the levers farther
forward. To slow down
smoothly, slowly move
the levers back toward
neutral.
Figure 7. Move Control
Levers Gradually
WARNING
Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while travelling in reverse.

ADVANCED DRIVING
Executing an End-Of-Row Zero
Turn
Your zero turn rider’s unique ability to turn in
place allows you to turn around at the end of
a cutting row rather than having to stop and
make a Y-turn before starting a new row.
For example, to execute a right end-of row
zero turn:
1. Slow down at the end of the row.
2. Move the LEFT ground speed control
lever forward slightly while moving the
RIGHT ground speed control lever back to
center and then slightly back from center
(see Figure 12). Be sure to keep both
wheels moving to avoid turf damage.
3. Begin mowing forward again.
This technique turns the rider RIGHT and
slightly overlaps the row just cut - eliminating
the need to back up and re-cut missed grass.
As you become more familiar and experienced with operating the zero turn rider, you
will learn more maneuvers that will make your
mowing time easier and more enjoyable.
Remember, the more you practice, the better your control of the rider will be!
Practice Turning Around a Corner
While traveling forward allow one handle to gradually
return back toward neutral (see Figure 10). Practice several times before mowing.
NOTE: To prevent damaging your lawn by pivoting directly on the tire tread, it is best to keep both wheels going at
least slightly forward.

SERVICE & ADJUSTMENTS
GROUND SPEED CONTROL LEVER
ADJUSTMENT
The control levers have three adjustments:
To Adjust Control Lever Height: Pull the levers in
across the operator’s lap to their DRIVE positions.
Loosen the mount bolts (D, Figure 32) and raise or lower
the levers to the desired position. Tighten the mounting
bolts.(D).
To Adjust Control Lever End Gap: The control lever
end gap should be adjusted so that the levers do not
contact each other when placed in DRIVE positions.
Loosen the jam nut (A, Figure 32) and adjust the length
of the carriage bolt (B) so that the levers do not contact
each other. Repeat on the opposite side. Tighten the jam
nut (A) to lock the carriage bolt in position.
To Adjust Operator Clearance: The space between the
operator and the control levers can be increase by
removing the lower mounting bolt (D, Figure 32), pivoting
the lever forward, and reinstalling the capscrew through
the control lever and forward slot (C). Repeat with the
other ground speed lever.
SPEED BALANCING ADJUSTMENT
If the rider veers to the right or left when the ground
speed control levers are in the maximum forward position, the top speed of the right lever can be balanced by
turning the adjustment knob (E, Figure 32). Loosen the
jam nut and turn the knob COUNTERCLOCKWISE to
increase speed or CLOCKWISE to decrease speed.
Tighten the jam nut when complete.
CUTTING HEIGHT ADJUSTMENT
To increase the mower cutting height (raise the mower
deck), press the top of the mower cutting height switch
(A, Figure 33). To decrease mower cutting height (lower
the mower deck), press the bottom of the switch. Mower
cutting height range is 3-3/4” to 1-1/2” (9,5-3,8 cm). The
cutting height gauge indicates the position of the mower
deck. The cutting height gauge (B) is located on the front
of the rider, just behind the driver’s left leg.

Corrosion hazard.
Batteries contain acid. Always keep the
battery upright and do not spill the
electrolyte. Avoid contact with skin and
eyes.
Explosion hazard.
Changing the battery produces explosive
hydrogen gas. Only charge the battery in a
well ventilated area, away from any ignition
source such as a water heater, electric
motor, or a lit cigarette.
Wear Protective Equipment
Always wear gloves and safety glasses
when handling the battery and battery
cables.
BATTERY CHARGING
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other

cause of the problem, contact your local dealer. If you
need to replace the battery, follow the steps under
CLEANING THE BATTERY & CABLES in the
Maintenance Section.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte temperature is at least 60° F). Do not charge at a rate higher
than 10 amps.
ENGINE ADJUSTMENTS
The engine is designed to deliver the correct performance under all operating conditions. Any adjustments
