safely enough to protect themselves and others
from serious injury.
29. If situations occur which are not covered in this
manual, use care and good judgment. Contact your
customer service representative for assistance.
SLOPE OPERATION
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
unit on a sloped or hilly area. If the slope is greater 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 a slope. If tires lose
traction, disengage the blade(s) and proceed
slowly straight down the slope.
DO NOT:
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. Overspeeding 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
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.
4
Page 5
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.
9. 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
SAFE HANDLING OF 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 ½ 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 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.
l. 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 SERVICE:
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 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).
5
Page 6
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.
WARNING: YOUR RESPONSIBILITY- Restrict the use of this power machine to persons who
read, understand and follow the warnings and instructions in this manual and on the machine.
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.

Slope Gauge
Operate RIDING mowers up and down slopes, never across the face of slopes.
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). A riding mower
could overturn and cause serious injury. If operating a walk-behind mower on such a slope, it is extremely difficult to maintain
your footing and you could slip, resulting in serious injury.

Removing Shipping Brace
WARNING: The shipping brace, used for
packaging purposes only, must be removed
and discarded before operating your riding
mower.
WARNING: Make sure the riding mower’s
engine is off, remove the ignition key, and set
the parking brake before removing the
shipping brace.
• Locate the shipping brace and accompanying
warning tag on the right side of the mower, between
the discharge chute and the cutting deck. See
Figure 5.
• While holding the discharge chute with your left
hand, remove the shipping brace with your right
hand by grasping it between your thumb and index
finger and rotating it clockwise.
• Carefully allow the discharge chute to pivot
downward.
• Discard the shipping brace and accompanying
warning tag.
• 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, simply
remove the mulch plug by unthreading the plastic wing
nut which fastens it to the cutting deck. This will allow
the clippings to discharge out the side. See Figure 6.

Figure 5
Installing The Mulching Plug (If Equipped)
NOTE: Your mulching plug may already be installed
on the deck.
Some lawn tractors come equipped with a mulch kit
which incorporates special blades, already standard on
all tractor, in a process of recirculating grass clippings
repeatedly beneath the cutting deck. The ultra-fine
clippings are then forced back into the lawn where they
act as a natural fertilizer. Observe the following
recommendations for the best results when mulching.
NOTE: The mulch kit is installed on models equipped
with a 38” or 42-inch deck. It is packed separately (with
an instruction sheet) in the crate on models equipped
with a 46-inch deck.

washers or garden hose to clean your unit. They
may cause damage to electric components,
spindles, pulleys, bearings or the engine. The use
of water will result in shortened life and reduce
serviceability.
• Lubricate all lubrication points. Wipe the entire
machine with an oiled rag to protect the surfaces.
• Refer to the engine manual for correct engine
storage instructions. The engine must be
completely drained of fuel to prevent gum deposits
from forming on essential carburetor parts, fuel
lines and fuel tanks.
Charge battery fully. The battery loses some of its
charge each day when the unit is not used.
NEVER store battery without a full charge. Recharge
battery before returning to service or every two months,
whichever occurs first.
• When storing unit for extended periods, disconnect
battery cables. Removing battery from unit is
recommended.
• Store unit in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rustproof the equipment. Using a light oil or
silicone, coat the equipment, especially any chains,
springs, bearings and cables.

will not start
Possible
Cause(s)
Safety switch
button not
depressed.
Battery installed
incorrectly.
Battery is dead
or weak.
Blown fuse or
circuit breaker.
Engine ground
wire loose.
Throttle or choke
not in starting
position.
No fuel to the
carburetor.
No spark to
spark plug.
Corrective Action
There are two switches in the starting circuit of your unit: the clutch pedal switch and
the deck lift lever switch. Make certain the actuator is fully depressing the buttons on
each switch.
The battery must be installed with negative terminal attached to black ground wire.
Negative terminal is identified at the post by “NEG”, “N” or “-”. The positive terminal,
identified by “POS”, “P” or “+”, must be attached to the big red wire which goes to the
solenoid. All batteries are to be fully charged before installing. Refer to “Quick Start”
battery guide that came with the operator’s manual.
Check fluid level in battery. If fluid is low, fill to just below split rings with water. Charge
with 6 AMP charger until fully charged.
Refer to operator’s manual for fuse box location. Replace fuse with automotive type
fuse. Fuses seldom fail without a reason. The problem must be corrected. Check for
loose connections in the fuse holder. Replace fuse holder if necessary. A dead short
may be in the cranking or charging circuit where the insulation may have rubbed
through and exposed the bare wire. Replace the wire or repair with electrician's tape if
the wire strands have not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or
muffler or rubbed against a moving part.
Engine should have a black ground wire running from engine to frame or mounting
bolt.
Check operator's manual for correct position for throttle control and choke for starting.
Gasoline tank empty. Fill.
Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace filter if
necessary.
Spark plug lead disconnected. Connect lead.
Faulty spark plug. To test, remove spark plug. Attach spark plug lead to spark plug.
Ground the spark plug body against the engine block. Crank the engine. The spark
plug should fire at the electrode. Replace if it does not.
