turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.
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.
• Turn off blade(s) when not mowing.
• Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.
• 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.
• Do not put hands or feet under cutting deck or near
rotating parts.
• Mow only in daylight or good artificial light.
• 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.
• 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.
• Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
• Never carry passengers.
• 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.
• 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.
• 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.
• Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.

• Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.
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.
• Your mower is designed to cut normal residential
grass of a height no more than 10". Do not attempt
to mow through unusually tall, dry grass (e.g.,
pasture) or piles of dry leaves. Debris may build up
on the mower deck or contact the engine exhaust
presenting a potential fire hazard.
• 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
2. SLOPE OPERATION
for small children.
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.
• Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
the safe machine operation.
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.
• 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.
DO:
• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
• 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.
4. SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• Use slow speed. Always keep machine in gear
when going down slopes to take advantage of
engine braking action.
• 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.
• Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve
stability.
• Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a
fire or explosion.
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• Extinguish all cigarettes, cigars, pipes and other
• 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.
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.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
• 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.
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.
• 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.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• 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 original equipment specifications.
• Do not try to stabilize the machine by putting your
foot on the ground.
• Do not use grass catcher on steep slopes.

parking brake, the engine will shut off.
• 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.
IMPORTANT: The PTO lever cannot be in the
engaged (ON) position when the tractor is driving in
the reverse direction. The safety interlock system will
automatically shut off the engine if the PTO lever is
moved into the engaged (ON) position with the shift
lever in the REVERSE position. Refer to SAFETY
INTERLOCK SWITCHES earlier in this section.
• 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.
MOWING
• Keep the blades sharp and replace the blades
when worn. Refer to the MAINTENANCE
section of this manual for proper blade
sharpening instructions.
This tractor comes equipped with a cutting deck. The
following information will be helpful when using the

It is extremely important that each cutting blade
edge be ground equally to maintain proper blade
balance. An unbalanced blade will 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 blade
balancer or round shaft screwdriver. Grind metal
from the heavy side until it balances evenly.
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.
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.
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.
IMPORTANT: Use a torque wrench to tighten the
blade spindle hex flange nut to between 70 foot-
pounds and 90 foot-pounds.
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
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 21 to determine if it is good or bad.
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.

c. Routine maintenance items such as lubricants, filters,
blade sharpening and tune-ups, or adjustments such
as brake adjustments, clutch adjustments or deck
adjustments; and normal deterioration of the exterior
finish due to use or exposure.
The limited warranty set forth below is given by MTD
PRODUCTS INC (“MTD”) with respect to new merchandise
purchased and used in the United States, its possessions
and territories.
d. MTD does not extend any warranty for products sold
or exported outside of the United States of America,
its possessions and territories, except those sold
through MTD’s authorized channels of export distribu-
tion.
MTD warrants this product against defects in material and
workmanship for a period of two (2) years commencing on
the date of original purchase and will, at its option, repair or
replace, free of charge, any part found to be defective in
material or workmanship. This limited warranty shall only
apply if this product has been operated and maintained in
accordance with the Operator’s Manual furnished with the
product, and has not been subject to misuse, abuse, com-
mercial use, neglect, accident, improper maintenance,
alteration, vandalism, theft, fire, water or damage because
of other peril or natural disaster. Damage resulting from the
installation or use of any accessory or attachment not
approved by MTD Products Inc. for use with the product(s)
covered by this manual will void your warranty as to any
resulting damages.
No implied warranty, including any implied warranty of
merchantability or fitness for a particular purpose,
applies after the applicable period of express written
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
entity, including a dealer or retailer, with respect to any
product shall bind MTD. During the period of the War-
ranty, the exclusive remedy is repair or replacement of
the product as set forth above. (Some states do not
allow limitations on how long an implied warranty lasts, so
the above limitation may not apply to you.)
Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear part or compo-
nent failures will be covered on the product for a period of
90 days regardless of cause. After 90 days, but within the
two year period, normal wear part failures will be covered
ONLY IF caused by defects in material or workmanship of
OTHER component parts. Normal wear parts and compo-
nents include, but are not limited to, belts, blades, blade
adapters, grass bags, rider deck wheels, seats, snow
thrower skid shoes, shave plates and tires. Batteries are
covered by a 90-day limited replacement warranty.
The provisions as set forth in this Warranty provide the
sole and exclusive remedy arising from the sales. MTD
shall not be liable for incidental or consequential loss
or damages including, without limitation, expenses
incurred for substitute or replacement lawn care ser-
vices, for transportation or for related expenses, or for
rental expenses to temporarily replace a warranted
product. (Some states do not allow the exclusion or limita-
tion of incidental or consequential damages, so the above
exclusion or limitation may not apply to you.)

of the safety features of the product shall void this War-
ranty. You assume the risk and liability for loss, damage, or
injury to you and your property and/or to others and their
property arising out of the use or misuse or inability to use
the product.
