SlopeOperation

Slopes are a major factor related to toss of control and tip-
over accidents which can result insevere injury or death. All
slopes require extra caution. If you cannot back up the slope
or if you feel uneasy on it, do not mow it.

For your safety, use the slope gauge included as part of this
manual to measure slopes before operating this unit on a
sloped or hilly area. If the slope isgreater than 15 degrees as
shown on the slope gauge, do not operate this unit on that
area or serious injury could result.

Do:

1. Mow up and down slopes, not across. Exercise extreme
caution when changing direction on slopes.

2. Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine. Tall
grass can hide obstacles.

3. Use slow speed. Choose a low enough speed setting so
that you will not have to stop or shift while on the slope.
Tires may lose traction on slopes even though the brakes
are functioning properly. Always keep machine in gear

when going down slopes to take advantage of engine

braking action.

4. Follow the manufacturer's recommendations for wheel

weights or counterweights to improve stability.

5. Use extra care with grass catchers or other attachments.
These can change the stability of the machine.

6. Keep all movement on the slopes slow and gradual. Do
not make sudden changes in speed or direction. Rapid
engagement or braking could cause the front of the
machine to lift and rapidly flip over backwards which
could cause serious injury.

7. Avoid starting or stopping on aslope. Iftires lose traction,
disengage the blade(s) and proceed slowly straight down
the slope.

DoNot:

1. Do not turn on slopes unless necessary; then, turn slowly
and gradually downhill, if possible.

2. 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, ditch, or if an edge caves in.

3. Do not try to stabilize the machine by putting your foot on
the ground.

4. Do not use a grass catcher on steep slopes.

5. Do not mow on wet grass. Reduced traction could cause
sliding.

6. Do not shift to neutral and coast downhill. Over-speeding
may cause the operator to lose control of the machine
resulting in serious injury or death.

7. Do not tow heavy pull behind attachments (e.g. loaded
dump cart, lawn roller, etc.) on slopes greater than 5
degrees. When going down hilt, the extra weight tends to
push the tractor and may cause you to loose control. (e.g.
tractor may speed up, braking and steering ability are
reduced, attachment may jack-knife and cause tractor to
overturn).

Children

1. Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. They do not
understand the dangers. Never assume that children will
remain where you last saw them.

a. Keep children out of the mowing area and in

watchful care of a responsible adult other than the
operator.

b. Be alert and turn machine off if a child enters the

area.

c. Before and while backing, look behind and down

for small children.

d. Never carry children, even with the blade(s) shut

off. They may fall off and be seriously injured or
interfere with safe machine operation.

e. Use extreme care when approaching blind

corners, doorways, shrubs, trees or other objects
that may block your vision of a child who may run

into the machine.

f. Disengage the cutting blade(s) before shifting in

reverse. The "No-Cut-In Reverse" feature is a
reminder not to cut in reverse and to help avoid

back over accidents. Do not defeat it.

g. Keep children away from hot or running engines.

They can suffer burns from a hot muffler.

h. Remove key when machine is unattended to

prevent unauthorized operation.

2. Never allow children under 14 years old to operate the
machine. Children 14 years old and over should read and

understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent.

Towing

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 manufacturers recommendation for weight
limits for towed equipment and towing on slopes.

3. Never allow children or others in or on towed equipment.

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 downhill.

Service

Gasoline:

1,

To avoid personal injury or property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite. Wash
your skin and change clothes immediately.

a. Use only an approved gasoline container.

b. Never fill containers inside a vehicle or on atruck

or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle
before filling.

c. When practical, remove gas-powered equipment

from the truck or trailer and refuel it on the ground.

Ifthis is not possible, then refuel such equipment
on atrailer with a portable container, rather than
from a gasoline dispenser nozzle.

d. Keep the 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.

e. Extinguish all cigarettes, cigars, pipes and other

sources of ignition.

f. Never fuel machine indoors.
g. Never remove gas cap or add fuel while the

engine is hot or running. Allow engine to cool at
least two minutes before refueling.

h. Never over fill fuel tank. Fill tank to no more than

½ inch below bottom of filler neck to allow space
for fuel expansion.

i. Replace gasoline cap and tighten securely.

j. Ifgasoline is spilled, wipe it off the engine and

equipment. Move unit to another area. Wait 5

minutes before starting the engine.

k. To reduce fire hazards, keep machine free of

grass, leaves, or other debris build-up. Clean up
oil or fuel spillage and remove any fuel soaked

debris.

1. Never store the machine or fuel container inside
where there is an open flame, spark or pilot light

as on a water heater, space heater, furnace,
clothes dryer or other gas appliances.

m.

Allow a machine to cool at least 5 minutes before
storing.

General:

1.

Never run an engine indoors or in a poorly ventilated
area. Engine exhaust contains carbon monoxide, an
odorless, and deadly gas.

2.

Before cleaning, repairing, or inspecting, make certain
the blade(s) and all moving parts have stopped.
Disconnect the spark plug wire and ground against the
engine to prevent unintended starting.

3.

Periodically check to make sure the blades come to
complete stop within approximately (5) five seconds after
operating the blade disengagement control. If the blades
do not stop within the this time frame, your unit should be

serviced professionally by your Troy-Bilt dealer.

4. Check brake operation frequently as it is subjected to
wear during normal operation. Adjust and service as
required.

5. Check the blade(s) and engine mounting bolts at
frequent intervals for proper tightness. Also, visually

inspect blade(s) for damage (e.g., excessive wear, bent,

cracked).

Replace the blade(s) with the original equipment
manufacturer's (O.E.M.) blade(s) only, listed in this

manual. "Use of parts which do not meet the original
equipment specifications may lead to improper
performance and compromise safety!"

6. Mower blades are sharp. Wrap the blade or wear gloves,
and use extra caution when servicing them.

7. Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

8. Never tamper with the safety interlock system or other
safety devices. Check their proper operation regularly.

9. After striking a foreign object, stop the engine, disconnect
the spark plug wire(s) and ground against the engine.
Thoroughly inspect the machine for any damage. Repair
the damage before starting and operating.

10. Never attempt to make adjustments or repairs to the

machine while the engine is running.

11. Grass catcher components and the discharge cover are
subject to wear and damage which could expose moving
parts or allow objects to be thrown.

For safety protection, frequently check components and

replace immediately with original equipment

manufacturer's (O.E.M.) parts only, listed in this manual.
"Use of parts which do not meet the original equipment
specifications may lead to improper performance and
compromise safety!"

12. Do not change the engine governor settings or over-
speed the engine. The governor controls the maximum
safe operating speed of the engine.

13. Maintain or replace safety and instruction labels, as
necessary.

14. Observe proper disposal taws and regulations for gas,
oil, etc. to protect the environment.

Idvi I Tie Tractor

• Depress the brake pedal to release the parking brake.

• Move the throttle lever into the FAST (rabbit) position.

• To move forward, place the shift lever in the FORWARD position, then slowly depress the drive pedal until the
desired speed is achieved. To move in reverse, place the shift lever in the REVERSE position, check that the
area behind is clear, then slowly depress the drive pedal.

DrivingOnSlopes

IMPORTANT:Refer to the SLOPEGAUGEon page 6 to help determine slopes where you may operate the tractor safely.

• Mow up and down slopes, never across.

• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall

grass can hide obstacles.

• Avoid turns when driving on a slope. If a turn must be made, attempt while going downward on the slope.

• Avoid stopping when driving up a slope. If it is necessary to stop while driving up a slope, start up smoothly and
carefully to reduce the possibility of flipping the tractor over backward.

The following information will be helpful when using the cutting deck with your tractor.

• Do not mow at high ground speed, especially if a mulch kit or grass collector is installed.

13

• For best results it is recommended that the first two laps be cut with the discharge thrown towards the center.
After the first two laps, reverse the direction to throw the discharge to the outside for the balance of cutting. This

will give a better appearance to the lawn.

• Do not cut the grass too short. Short grass invites weed growth and yellows quickly in dry weather.

• Mowing should always be done with the engine at full throttle.

• Under heavier conditions it may be necessary to go back over the cut area a second time to get a clean cut.

• Do not attempt to mow heavy brush and weeds and extremely tall grass. Your tractor is designed to mow lawns,
not clear brush.

• Keep the blades sharp and replace the blades when worn. Refer to CuttingBladeson page 19 of this manual for
proper blade sharpening instructions.

_ WARNING" To help avoid blade contact or a thrown object injury, keep bystanders, helpers, childrenand pets at least 75 feet from the machine while it is in operation. Stop machine if anyone enters the area.

Mulching

Some models are equipped with a mulch kit with special blades to recirculate the grass clippings into the lawn
where they act as a natural fertilizer.

• On models with 46-inch decks, where the mulch kit is packed separately within the tractor's crate, follow the
instructions included with the mulch kit.

Observe the following points for best results when mulching.

• Never attempt to mulch if the lawn is damp. Wet grass tends to stick to the underside of the cutting deck
preventing proper mulching of the clippings.

• Do not attempt to mulch more than 1/3 the total height of the grass or approximately 1-1/2 inches. Doing so will
cause the clippings to clump up beneath the deck and not be mulched effectively.

• Maintain a slow ground speed to allow the grass clippings more time to effectively be mulched.

• Always position the throttle control lever in the FAST (rabbit) position and allow it to remain there while mowing.
Failing to keep the engine at full throttle places strain on the tractor's engine and does not allow the blades to
properly mulch grass.

NOTE: It is not necessary to remove the discharge chute to operate the mower with the mulch kit installed.

To operate the cutting deck without mulching, on
models so equipped, simply remove the mulch plug by
unthreading the plastic wing nut which fastens itto the
cutting deck. See Figure 6. This will allow the clippings
to discharge through the side opening.
