SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-
over 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 distri-
bution.
1. Mow across the face of slopes, not up and down.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
4. Do not mow on wet grass. Tires may lose traction.
5. Never mow down slopes.
6. 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-
ly off the slope.
7. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
8. 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.
9. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
10. Do not mow near drop-offs, ditches, or embank-
ments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an edge
caves in.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes if you cannot back up them.
13. See your authorized dealer/retailer for recommenda-
tions of wheel weights or counterweights to improve
stability.
14. Remove obstacles such as rocks, tree limbs, etc.
15. Use slow speed.Tires may lose traction on slopes
even through the brakes are functioning properly.
16. 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)
1. Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturer's recommendations for
weight limit for towed equipment and towing on
slopes. See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed equip-
ment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. 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 rear-
mounted 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.
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.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. 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.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.

container opening at all times until fueling is com-
plete. Do not use a nozzle lock-open device.
9. If fuel is spilled on clothing, change clothing immedi-
ately.
10. Never over-fill the fuel tank. Replace gas cap and
tighten securely.
11. Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
12. 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.
13. Replace all fuel tank caps and fuel container caps
securely.
Service & Maintenance
1. Never run the unit in an enclosed area where carbon
monoxide fumes may collect.
2. Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.

gloves, and use extra caution when servicing them.
9. Check brake operation frequently. Adjust and service
as required.
10. Maintain or replace safety and instructions labels, as
necessary.
11. Do not remove the fuel filter when the engine is hot
as spilled gasoline may ignite. Do not spread fuel line
clamps further than necessary. Ensure clamps grip
hoses firmly over the filter after installation.
12. Do not use gasoline containing METHANOL, gasohol
containing more than 10% ETHANOL, gasoline addi-
tives, or white gas because engine/fuel system dam-
age could result.
13. If the fuel tank must be drained, it should be drained
outdoors.
14. Replace faulty silencers/mufflers.
15.Maintain or replace safety and instruction labels as
necessary.
16. Use only factory authorized replacement parts when

Figure 1. Controls
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences. To learn what combination and sequence
of controls to use for various tasks please read the entire section.
Ground Speed Levers /
Parking Brake
These levers control the ground speed and parking brake
of the rider. The left lever controls the left rear drive
wheel and the right lever controls the right rear drive
wheel and parking brake.
Pushing the levers out, away from the operator's lap
locks the parking brake in PARK position (inset, Figure
1). 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 fur-
ther a lever is pushed, the faster the drive wheel will turn.
See DRIVING PRACTICE for steering instructions. 10
[]'_- Throttle Control
The throttle controls engine speed. Always operate at
FULL throttle when mowing. Move the lever forward to
the detent for FULL throttle (FAST). Move the throttle
back to decrease engine speed to IDLE (SLOW).
W Choke
Close the choke for cold starting. Open the choke once
the engine starts. A warm engine may not require chok-
ing. Move the lever forward to close the choke. Move
the lever back to open the choke.
Mower Height of Cut Adjustment
To adjust cutting height, rotate the turn crank clockwise
to raise the mower deck and counterclockwise to lower
the mower deck.
ignition Switch
The ignition switch starts and stops the engine; it has
three positions:
OFF Stops the engine and shuts off the
electrical system.
BUN Allows the engine to run and powers the
electrical system.
START Cranks the engine for starting.
NOTE: Never leave the ignition switch in the RUN posi-
tion with the engine stopped. This drains the batter_4
[]Hour Meter
The hour meter measures the number of hours the key
has been in the RUN position.
NOTE: The hour meter will register the passage of time
when the key is in the RUN position, even if the engine is
not running.
_PTO Switch
The PTO (Power Take-Off) switch engages and disen-
gages the mower deck. To turn the mower on, pull the
switch UP. Push the switch DOWN to turn the mower off.
Note that the operator must be seated firmly in the rider
seat for the PTO to function.

becoming familiar with the location and function
of ALL controls,
11
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 Tedary Butyl Ether (MTBE)
and unleaded gasoline blends (up to a maximum of 15%
MTBE by volume) are approved as a fuel. No other gaso-
line/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 mois-
ture 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 addi-
tional 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 2).
2. Fill the tank. Do not overfill. Leave room in the tank
for fuel expansion.
3. Install and hand tighten the fuel cap.

trol levers to PARK, turn the ignition switch OFF,
remove the key, and wait for all moving parts to stop.
Locate the transmission release levers (C, Figure 3)
at the rear of the unit.
Pull both levers back and down to release the trans-
missions (position B, Figure 3).
Set the ground speed control levers to DRIVE posi-
tions (levers moved in).
The rider can now be pushed by hand.
After moving the rider, set the ground speed control
levers to PARK and push both transmission release
levers forward to re-engage the transmissions (posi-
tion A, Figure 3).
DO NOT TOW RIDER
®
Towing the unit will cause transmission dam-
age. Do not use another vehicle to push or
pull this unit.
4. After the engine starts, gradually move the choke
control back to OPEN position. Warm the engine by
running it for at least a minute before turning on the
PTO switch, or driving the unit.
5. After warming the engine, ALWAYS operate the
unit with the throttle set to FAST, especially when
mowing.
MOWING
1. Make sure the PTO switch is OFF, the ground speed
control levers are locked in their PARK positions, and
the operator is in the seat.
2. Set the mower cutting height to the desired setting.
3. Start the engine (see STARTING THE ENGINE).
4. Set the throttle to FAST.
5. Turn the PTO switch ON to engage the mower deck.

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 four-
wheeled vehicles. The drive wheels are also your steer-
ing 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 respon-
sive, 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.
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 4.
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 4. Move Control
Levers Gradually
Forward Travel Practice
Gradually move both ground speed control levers evenly
FORWARD from neutral. Slow down and repeat.
Reverse Travel Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
WARNING
Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while travelling in reverse,
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.
Reverse Travel
Forward Travel _
Figure 5. Forward Travel Figure& Reverse Travel
14
PracticeTurning Around a Corner
While traveling forward allow one handle to gradually
return back toward neutral. Practice several times before
mowing.
NOTE: To prevent damaging your lawn by pivoting direct-
lyon the tire tread, it is best to keep both wheels going at
least slightly forward.
PracticeTurning In Place
To "zero turn" means to turn in place. To turn in place,
gradually move one ground speed control lever forward
from neutral and one lever back from neutral simultane-
ously. Repeat several times.
Executing Turns
Figure 7. RightTurn Figure 8. Turning in Place
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.
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 experi-
enced 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 bet=
ter your control of the rider will be!

CHECK / ADJUST PTO CLUTCH
WARNING
To avoid serious injury, perform adjustments only
with engine stopped, key removed and tractor on
level ground.
Service Interval: 200 Hours.
The PTO clutch is engaged and disengaged by the PTO
switch. The clutch powers and brakes the mower blades.
Check the PTO clutch adjustment every 200 hours of
operation. Also perform the following procedure if the
clutch is slipping, will not engage, or if a new clutch has
been installed.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of acciden-
tal starting while the PTO is being adjusted.
2. See Figure 22. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
3. Insert a .012"-.015" (2,5-4mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 23.
4. Alternately tighten the adjustment nuts (B, Figure 22)
until the rotor face and armature face just contacts
the gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosen-
ing the adjustment nuts.
NOTE: The actual air gap between the rotor and arma-
ture may vary even after performing the adjustment pro-
cedure. This is due to dimensional variations on compo-
nent parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a com-
plete stop within five seconds after the electric PTO
switch is turned off. If adjustment does not stop a
mower braking problem, replace the electric PTO
clutch.

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 34) 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 34), 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 posi-
tion, the top speed of the right lever can be balanced by
turning the adjustment knob (E, Figure 34). Loosen the
jam nut and turn the knob COUNTERCLOCKWISE to
increase speed or CLOCKWISE to decrease speed.
Tighten the jam nut when complete.

See CHECK / ADJUST PTO CLUTCH in the
Maintenance Section.
BRAKE ADJUSTMENT
1. Stop the unit, turn the ignition OFF, set the ground
speed levers to PARK positions, and wait for all mov-
ing parts to stop.
2. Locate the brake rod (A) and adjustment nut (B).
4. Measure the parking brake spring. Its compressed
length, with the ground speed levers in their PARK
positions should be 3" (7.62cm). Adjust the spring
length by turning the adjustment nut (B), if necessary.
BATTERY CHARGING

A, Cutting Height Adjustment Crank
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
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
electrical component. If there is any doubt about the
cause of the problem, contact a Sears Parts & Repair
Center. If you need to replace the battery, follow the
steps under Cleaning the Battery & Cables in the
Regular 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 tem-
perature 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 perform-
ance under all operating conditions. Any adjustments
must be performed by a Sears or other qualified service
dealer.

MOWER DECK LEVELING
ADJUSTMENTS
WARNING
Before checking mower, shut off PTO and engine.
Allow all moving parts to stop. Remove ignition
key, then disconnect the spark plug wire and
fasten it away from the spark plug.
Side to Side Leveling
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. See CHECK TIRE PRESSURE.
1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward. Turn the engine off,
set the ground speed control levers to PARK, and
wait for all moving parts to stop.
2. Check for bent blades and replace if necessary.
3. Check the tire pressures. See CHECK TIRE PRES-
SURE.
4. Set the cutting height to mid position. Arrange the
mower blades so that they are pointing from side-to-
side (Figure 38).
5. Measure the distance between the tips of the outside
blades and the ground (Figures 37 & 38). If there is
more than 1/8" (3mm) difference between the meas-
urements on each side, proceed to step 6. If the dif-
ference is 1/8" (3ram) or less, proceed to Front To
Back Leveling.
6. See Figure 39. Loosen the outside nut (A) and taptite
screw (C), then turn the eccentric nut (B) to raise or
lower the left side of the deck. When the mower deck
is level, hold the eccentric nut while tightening the
outside nut. Tighten the taptite screw (C).
