SlopeOperation
Slopes are a major factor related to loss of control and tip-over
accidents which can result in severe 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 machine on
a sloped or hilly area. If the slope is greater than 15 degrees as
shown on the slope gauge, do not operate this machine 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 a slope. If tires 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 isover 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 agrass 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 hill, the extra weight tends
to push the tractor and may causeyou to loose control
(e.g.tractor may speed up, braking and steering ability are
reduced, attachment may jack-knife and cause tractor to
overturn).
4, I SECTION2 -- IMPORTANT SAFE OPERATION PRACTICES

Children
1. Tragic accidents ca n 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 offand 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
blockyour vision of a child who may run into the
path of the machine.
f. To avoid back-over accidents, always disengage
the cutting blade(s) before shifting into Reverse.
If equipped, the "Reverse Caution Mode" should
not be used when chUdren or others are around.
2.
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.
Never allow children under 14 years of age to operate this
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and should be trained and supervised
by an adult.
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. Always use extra caution when towing with a machine
capable of making tight turns (e.g. "zero-turn" ride-on
mower). Make wide turns to avoid jack-knifing.
6. Travel slowly and allow extra distance to stop.
7. Do not shift to neutral and coast downhill.
Service
SafeHandlingof 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 a truck
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.
If this is not possible, then refuel such equipment on
a trailer 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 1/2
inch below bottom of filler neck to allow space for
fuel expansion.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine and
equipment. Move machine 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.
I. 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 five minutes before
storing.
GeneralService
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.
SECTION 2 -- IMPORTANT SAFE OPERATION PRACTICES S

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 machine
should be serviced professionally by an authorized MTD
Service 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 laws and regulations for gas, oil,
etc. to protect the environment.
15. According to the Consumer Products Safety Commission
(CPSC) and the U.S. Environmental Protection Agency (EPA),
this product has an Average Useful Life of seven (7) years,
or 270 hours of operation. At the end of the Average Useful
Life have the machine inspected annually by an authorized
service dealer to ensure that all mechanical and safety
systems are working properly and not worn excessively.
Failure to do so can result in accidents, injuries or death.
Donotmodifyengine
To avoid serious injury or death, do not modify engine in any
way. Tampering with the governor setting can lead to a runaway
engine and cause it to operate at unsafe speeds. Never tamper
with factory setting of engine governor.

"browned" by hot exhaust from your tractor's running engine.
Driving OnSlopes
Refer to the SLOPE GAUGE in the Important Safe Operation
Practices section in the front of this manual to help determine
slopes where you may operate the tractor safely.
WARNING! Do not mow on inclines with a slope in
excess of 15 degrees (a rise of approximately2-1/2 feet
every 10feet). The tractor could overturn and cause
serious injury.
Mow up and down slopes, NEVER across.
Exercise extreme caution when changing direction on
slopes.
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. Ifa turn must be
made, turn down the slope. Turning up a slope greatly
increases the chance of a roll over.
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.

'°1SECTION S-- OPERATION

Usingthe DeckLiftLever
To raise the cutting deck, move the deck lift lever to the left, then
place it in the notch best suited for your application. Refer to
Setting The Cutting Height earlier in this section.
Mowing
WARN[ NG! To help avoid blade contact or a
thrown object injury, keep bystanders, helpers,
children and pets at least 75 feet from the machine
while it is in operation. Stop machine if anyone
enters the area.
The following information will be helpful when using the cutting
deck with your tractor:
i_i WARNING! Plan your mowing pattern to avoid
discharge of materials toward roads, sidewalks,
bystanders and the like. Also, avoid discharging
material against a wall or obstruction which may
cause discharged material to ricochet back toward
the operator.
Do not mowat high ground speed, especially ifa mulch kit
or grass collector is installed.
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.
Referto Cutting Blades in the Service section of this manual
for proper blade sharpening instructions.
Headlights
The Headlights are ON whenever the tractor's engine is
running.
The lamps turn OFF when the ignition key is moved to the
STOP position.
