Safety Rules and Information
SLOPE OPERATION
WARNING
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 can-
not back up the slope or if you feel uneasy on it, do not
operate on it.
Control of a ride-on machine sliding on a slope will not be
regained by the application of the brake. The main rea-
sons 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.
1. Mow up and down slopes, not across.
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 loose traction.
5. Always keep unit in gear especially when traveling
down slopes. Do not shift to neutral and coast down-
hill.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction, disengage the blade(s) and proceed
slowly straight down 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 attachment; they can affect the sta-
bility of the unit.
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.
When operating on slopes use additional wheel
weights or counterweights. See your dealer to
determine which weights are available and
appropriate for your unit.
Select slow ground speed before driving onto slope.
In addition to front and rear weights, use extra caution
when operating on slopes with rear-mounted grass
catcher.
Mow UP and DOWN the slope, never across the
face, 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.
9. Do not try to stabilize the machine by putting your
foot on the ground.
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 you cannot back up.
13. See your authorized dealer for recommendations 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 downhill, if possible.
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.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
TOWED EQUIPMENT
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.
3. Never allow children or others in or on towed equip-
ment.
IGNITION SYSTEM
1. This spark ignition system complies with Canadian
ICES-002.
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.

Safety Rules & Information
SERVICE AND MAINTENANCE
Safe Handling of Gasoline
1. Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
12. Grass catcher components are subject to wear, dam-
age, and deterioration, which could expose moving
parts or allow objects to be thrown. Frequently check
components and replace with manufacturer’s recom-
mended parts, when necessary.
2. Use only approved gasoline containers.
3. Never remove the gas cap or add fuel with the engine
running. Allow the engine to cool before refueling.
4. Never fuel the machine indoors.
5. 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.
6. 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.
7. Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possi-
ble, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dis-
penser nozzle.
8. Keep nozzle in contact with the rim of the fuel tank or
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.
13. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution when
servicing them.
14. Check brake operation frequently. Adjust and service
as required.
15. Use only factory authorized replacement parts when
making repairs.
16. Always comply with factory specifications on all set-
tings and adjustments.
17. Only authorized service locations should be utilized
for major service and repair requirements.
18. Never attempt to make major repairs on this unit
unless you have been properly trained. Improper ser-
vice procedures can result in hazardous operation,
equipment damage and voiding of manufacturer’s
warranty.
19. On multiple blade mowers, take care as rotating one
blade can cause other blades to rotate.
20. Do not change engine governor settings or over-
speed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
21. Disengage drive attachments, stop the engine,
remove the key, and disconnect the spark plug
wire(s) before: clearing attachment blockages and
chutes, performing service work, striking an object, or
if the unit vibrates abnormally. After striking an
object, inspect the machine for damage and make
repairs before restarting and operating the equip-
ment.
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
22. Never place hands near the moving parts, such as a
hydro pump cooling fan, when the tractor is running.
(Hydro pump cooling fans are typically located on top
of the transaxle).
1. Maintain or replace safety and instruction labels as
necessary.
2. Never run the unit in an enclosed area where carbon
monoxide fumes may collect.
3. Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.
4. Never tamper with safety devices. Check their proper
operation regularly and make necessary repairs if
they are not functioning properly.
5. Keep unit free of grass, leaves, or other debris build-
up. Clean up oil or fuel spillage.
6. Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
7. Never make adjustments or repairs with the engine
running unless specified otherwise in the engine man-
ufacturer’s manual.
8. 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.
9. 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.
10. If the fuel tank must be drained, it should be drained
outdoors.
11. Replace faulty silencers/mufflers.

Troubleshooting,
Adjustments, & Service
TROUBLESHOOTING
While normal care and regular maintenance will extend
the life of your equipment, prolonged or constant use
may eventually require that service be performed to
allow it to continue operating properly.
WARNING
To avoid serious injury, perform maintenance on
the tractor or mower only when the engine is
stopped and the parking brake engaged.
Always remove the ignition key, disconnect the
spark plug wire and fasten it away from the plug
before beginning the maintenance, to prevent
accidental starting of the engine.
The troubleshooting guide below lists the most common
problems, their causes and remedies.

CATCHER-FULL ALARM
ADJUSTMENT
To adjust the “catcher full” alarm, slide the sensor plate
(A, Figure 30) forward or backward on the sensor rod. If
the chute is plugging, slide the plate backwards to
increase sensitivity. If the alarm is going on before the
hopper is full, slide the plate forwards to decrease sensi-
tivity.

MOWER LIFT ADJUSTMENT
The mower lift rod (A, Figure 31) can be inserted into two
holes depending on the amount of mower lift desired.
The upper hole provides higher mower lift when the
attachment lift lever is placed in transport position. The
lower hole will not lift the mower as high in transport
position, but requires less lift effort.

BATTERY CHARGING
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
Figure 31. Mower Lift Adjust
(Viewed from underneath right side of tractor)
A. Mower Lift Rod
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, see your dealer. 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 high-
er than 10 amps.

WARNING
To avoid serious injury, perform adjustments only
with engine stopped, key removed and tractor on
level ground.
Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 250 hours of opera-
tion. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.

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.

Leveling The Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci-
fied in Checking Tire Pressure.
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Disengage the PTO. Place the mower in mid-cut
position. Arrange one of the mower blades so that it
is pointing from side-to-side.

4. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8”
(3mm) difference between the measurements on
each side, proceed to step 5. If the difference is 1/8”
(3mm) or less, proceed to step 6.
5. See Figure 36. Loosen the outside nut (A). Turn the
eccentric nut (B) to raise or lower left-hand side of
mower. When mower is level, hold the eccentric nut
while tightening the outside nut.
