SECTION 4: IMPORTANT SAFE OPERATION PRACTICES
WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF
NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF
YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL
BEFORE ATTEMPTING TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH
THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL,
HEED ITS WARNING.
WARNING: The Engine Exhaust from this product contains chemicals known to
the State of California to cause cancer, birth defects or other reproductive harm.
DANGER: Your lawn mower was built to be operated according to the rules for safe operation in
this manual. As with any type of power equipment, carelessness or error on the part of the operator
can result in serious injury. This lawn mower is capable of amputating hands and feet and throwing
objects. Failure to observe the following safety instructions could result in serious injury or death.
1. GENERAL OPERATION
Read, understand, and follow all instructions in the
operator's manual and on the machine before
starting. Keep this manual in a safe place for future
and regular reference and for ordering replacement
parts.
Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.
Do not put hands or feet under cutting deck or near
rotating parts.
Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked
and could be accidentally thrown by the mower in
any direction and cause injury to you or a
bystander. To help avoid a thrown objects injury,
keep children, bystanders and helpers at least 75
feet from the mower while it is in operation. Always
wear safety glasses or safety goggles during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects. Stop
the blade(s) when crossing gravel drives, walks or
roads.
Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
Never carry passengers.
Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before
and while backing.
Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
Never leave a running machine unattended. Always
turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.
•Tum off blade(s) when not mowing.
Stop engine and wait until blade(s) comes to a
complete stop before (a) removing grass catcher or
unclogging chute, or (b) making any repairs,
adjusting or removing any grass or debris.
Mow only in daylight or good artificial light.
Do not operate the machine while under the
influence of alcohol or drugs.
Watch for traffic when operating near or crossing
roadways.
Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
Never make a cutting height adjustment while
engine is running if operator must dismount to do
SO.
Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals, or
sneakers.
Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving buildings,
or in any other situation where the operator may be
struck or pulled from the unit, which could result in
serious injury.

2. 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 ° as
shown on the slope gauge, do not operate this unit on that
area or serious injury could result.
DO:
Mow up and down slopes, not across.
Remove obstacles such as rocks, limbs, etc.
Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
Use slow speed. Always keep machine in gear
when going down slopes to take advantage of
engine braking action.
Follow the manufacturer's recommendations for
wheel weights or counterweights to improve
stability.
Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• 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.
Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
DO NOT:
Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
• 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 or ditch, or
if an edge caves in.
Do not mow on wet grass. Reduced traction could
cause sliding.
Do not try to stabilize the machine by putting your
foot on the ground.
Do not use grass catcher on steep slopes.
3. CHILDREN
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. Never assume that chil-
dren will remain where you last saw them.
Keep children out of the mowing area and in
watchful care of an adult other than the operator.
Be alert and turn machine off if children enter the
area.
Before and when backing, look behind and down
for small children.
Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
the safe machine operation.
Never allow children under 14 years old to operate
the machine. Children 14 years and over should
only operate machine under close parental
supervision and proper instruction.
• Remove key when machine is unattended to
prevent unauthorized operation.
Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
4. SERVICE
Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
Use only an approved container.
Never remove fuel cap or add fuel with the engine
running. Allow engine to cool at least two minutes
before refueling.
Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a
fire or explosion.
Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
Never refuel the machine indoors because fuel
vapors will accumulate in the area.
Never store the fuel container or machine inside
where there is an open flame or spark, such as a
gas hot water heater, space heater or furnace.
Never run a machine inside a closed area.
To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up oil
or fuel spillage. Allow machine to cool at least 5
minutes before storing.
Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent
accidental starting.
Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade for damage (e.g., excessive
wear, bent, cracked). Replace with blade which
meets odgina] equipment specifications.

MOWING
This tractor is equipped with one of MTD's high
quality cutting decks. The following information wilt
be helpful when using the cutting deck with your
tractor.
_, WARNING: TO avoid possible injury, do
not allow anyone in the area of the tractor
while mowing. Even if the area to be
mowed has been cleared of foreign
objects, small objects may be picked up
and discharged by the mower.
_, WARNING: Never direct the discharge
of material toward bystanders or allow
anyone near the machine while in
operation.
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 wilt
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.
Do not mow at high ground speed, especially
if a mulch kit or grass collector is installed.
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 the MAINTENANCE
section of this manual for proper blade
sharpening instructions.

_Hex Flange Nut Block of Wood
!
Cutting Blade
Figure 21
Use a 15/16" wrench to remove the hex flange
nut that secures the blade to the spindle
assembly. See Figure 21.
22
NOTE: The hex flange nut has a right-handed
(normal) thread pattern. Do NOT attempt to force the
nut in the incorrect direction. Doing so may damage
the nut and create a safety hazard.
To properly sharpen the cutting blades, remove
equal amounts of metal from both ends of the blades
along the cutting edges. See Figure 22.
Sharpen the cutting edge straight across, parallel to
the trailing edge, at a 25 ° to 30° angle. See Figure
22.
IMPORTANT: If the cutting edge of the blade has
already been sharpened to within 5/8" of the wind
wing radius, or if any metal separation is present,
replace the blades with new ones. See Figure 22.
Worn Blade Edge 7
Blade Separation Wind Wing
Sharpen EdgeT-'Evenly

Figure 22
It is extremely important that each cutting blade
edge be ground equally to maintain proper blade
balance. An unbalanced blade wilt cause excessive
vibration when rotating at high speeds, may cause
damage to the tractor and result in personal injury.
The blade can be tested by balancing it on a round
shaft screwdriver. Grind metal from the heavy side
until it balances evenly.
When replacing the blade, be sure to install the
blade with the side of the blade marked "Bottom" (or
with a part number stamped in it) facing the ground
when the mower is in the operating position.
IMPORTANT: Use a torque wrench to tighten the
blade spindle hex flange nut to between 70 foot-
pounds and 90 foot-pounds.
BATTERY
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
Always keep the battery cables and terminals
clean and free of corrosive build-up.
After cleaning the battery and terminals, apply
a light coat of petroleum jelly or grease to the
terminals and over the positive terminal boot.
• Always keep the boot positioned over the
positive terminal to prevent shorting.
IMPORTANT: If removing the battery for any
reason, disconnect the NEGATIVE (Black) wire from
it's terminal first, followed by the POSITIVE (Red)
wire. When re-installing the battery, always connect
the POSITIVE (Red) wire its terminal first, followed
by the NEGATIVE (Black) wire. Be certain that the
wires are connected to the correct terminals.
reversing them could change the polarity and cause
damage to your engine's alternating system.
Charging
If the unit has not been put into use for an extended
period of time, charge the battery with an
automotive-type 12-volt charger for a minimum of
one hour at six amps.
WARNING: Batteries give off an
explosive gas during and for some time
after charging. Charge battery in a well
ventilated area and do not allow a spark or
an open flame near the battery.
TIRES
The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for
the front tires. Refer to the tire sidewall for exact tire
manufacturer's recommended psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.
FUSE
A fuse is installed in your tractor's wiring harness to
protect the tractor's electrical system from damage
caused by excessive amperage. Always use the
same capacity fuse for replacement. If the electrical
system does not function, or your tractor's engine
will not crank, first check to be certain that the fuse
has not blown. It can be found under the hood
mounted behind the top of dash panel on the
support bar. Pull the fuse out and compare it with
Figure 23 to determine if it is good or bad.

SECTION 12: TROUBLESHOOTING GUIDE
Trouble Corrective Action
Engine will
not crank
Engine
cranks but
will not start
Possible
Cause(s)
Safety switch
button not
depressed.
Battery installed
incorrectly.
Battery is dead
or weak.
Blown fuse
Throttle or choke
not in starting
position.
No fuel to the
carburetor.
No spark to
spark plug(s).
There are three safety switches in the starting circuit of your unit: the brake pedal
switch, the seat switch and the PTO switch. Make certain the actuator found on the
brake control assembly is fully depressing the button on the brake switch. The PTO
must be in the disengaged (OFF) position and the operator must be seated on the
tractor in order to start the engine, also.
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 thick red wire which goes to the
solenoid.
Charge at six amps with a 12-volt automotive4ype battery charger for one hour or until
fully charged.
Refer to operator's manual for fuse location. Replace fuse with automotive type fuse of
the proper amperage. Fuses seldom fail without a reason. The problem must be
corrected. Check for loose connections in the fuse holder. Replace fuse holder if nec-
essary. 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.
Refer to the OPERATION section of this manual for the correct position of the throttle
control and choke for starting.
Gasoline tank empty. Fill.
Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace fuel filter
(if so equipped) if necessary.
Spark plug lead disconnected. Connect lead. Using a spark tester, check for spark. If
no spark is present, have engine's magneto serviced by an authorized engine dealer.
Dirty aircleaner. If the air cleaner is dirty, the engine may not start. Refer to the engine manual packed
with your unit.

the date of original purchase and will, at its option, repair or
replace, free of charge, any part found to be defective in

mercial use, neglect, accident, improper maintenance,
alteration, vandalism, theft, fire, water or damage because

OTHER component parts. Normal wear parts and compo-
nents include, but are not limited to, belts, blades, blade

warranty above as to the parts as identified. No other
express warranty or guaranty, whether written or oral,
except as mentioned above, given by any person or
