General Operation
•

•

•
•

•

Read, understand, and follow all instructions in the
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.
Turn 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 cutting height adjustment while engine
is running, if operator must dismount to do so.
Wear sturdy, rough-soled work shoes and closefitting 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.
Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.
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.

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 in 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. Choose a low enough gear so that
you will not have to stop or shift while on the slope.
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.

•

Service
•

•
•

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.

•

Children
•

•
•

Before and when backing, look behind and down
for small children.
Never carry children. 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.
Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
Remove key when machine is unattended to
prevent unauthorized operation.

•

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 children 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.

•

Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
a. Use only an approved container.
b. Never remove fuel cap or add fuel with the
engine running. Allow engine to cool at least
two minutes before refueling.
c. Replace fuel cap securely and wipe off any
spilled fuel before starting the engine as it may
cause a fire or explosion.
d. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
e. Never refuel the machine indoors because fuel
vapors will accumulate in the area.
f. 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 original equipment specifications.
Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.
After striking a foreign object, stop the engine,
remove the wire from the spark plug and thoroughly
inspect the mower for any damage. Repair the
damage before restarting and operating the mower.

•

•
•

•

Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For your
safety protection, frequently check components
and replace with manufacturer’s recommended
parts when necessary.
Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution when
servicing blade(s).
Check brake operation frequently. Adjust and
service as required.
Muffler, engine and belt guards become hot during
operation and can cause a burn. Allow to cool down
before touching.
Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.

•

Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can harm
the environment and the ecology.
a. Prior to disposal, determine the proper method
to dispose of waste from your local office of
Environmental Protection Agency. Recycling
centers are established to properly dispose of
materials in an environmentally safe fashion.
b. Use proper containers when draining fluids. Do
not use food or beverage containers that may
mislead someone into drinking from them.
Properly dispose of the containers immediately
following the draining of fluids.
c. DO NOT pour oil or other fluids into the ground,
down a drain or into a stream, pond, lake or
other body of water. Observe Environmental
Protection Agency regulations when disposing
of oil, fuel, coolant, brake fluid, filters, batteries,
tires and other harmful waste.

Safety Interlock

Cutting
Height

This unit is equipped with a safety interlock system for
your protection. The interlock safety switches are
connected to the brake pedal, the blade engagement
pedal, the shift lever, and the seat.

Shift
Lever

The purpose of the safety interlock system is threefold:

Figure 9

a. to prevent the engine from starting unless the
brake pedal is depressed and the blade
engagement pedal is disengaged;
b. to shut off the engine if the blade pedal is not
disengaged when the shift lever is put into
reverse; and
c. to shut the engine off when the operator leaves
the seat without engaging the parking brake.

•

WARNING: To avoid the risk of serious
injury, do not operate the rider mower if
the interlock system is malfunctioning.
•
•
•
•

•

Remove objects that could be thrown by the
blade(s).
Know location and function of all controls.
Be sure blade(s) and engine are stopped before
placing hands or feet near blade(s).
Before leaving operator's position, disengage
blade(s), place the shift lever in neutral, engage
parking brake, shut engine off and remove key.

Move the lever outwards (left) to remove the
locking pin from the lever and slide the lever to the
position desired. Look at the rear and make sure
the path is free of obstacles before positioning the
shift lever to the reverse.
Do not force the shift lever. If it does not shift,
release the brake pedal slightly to line up the
shifting collar in the transmission, then try to move
the shift lever.
Slowly release the brake pedal and take your foot

Grass Fill Level Indicator
This indicator was designed to add convenience to your
riding mower. While the mower is running, air will flow
through the discharge chute and into the grass catcher.
If the grass catcher is empty, air flows through easily
pushing the ball up. If the grass catcher is full, air does
not flow through it allowing the ball to fall. So if you see
the ball in the grass catcher fill level indicator falling
down, you should stop the mower and empty the bag.

Using Shift Lever
The shift lever is used to regulate the direction of your
rider mower. It can be set at forward, neutral, or reverse
settings. These settings, marked as F, N,and R
respectively, are located next to the shift lever on the

•

Mow grass often and in regular intervals so that you
can cut only 1/3 of the grass blade in one mowing.
To empty grass bag, stop the mower completely,
engage the parking brake, and turn the ignition off.
This will prevent the hot engine exhaust gas from
browning the grass.
Many communities no longer haul grass clippings
to landfills. Composting the clippings from your
grass catcher is a viable solution. For this you will
have to empty the grass catcher at the designated
composting site.
Your rider mower is equipped with a mulching plug
to mulch the grass and recycle into the lawn instead
of collecting in the grasscatcher bag.
Mulch only when the grass is dry. Mulching wet
grass may damage the underside of the deck
because wet grass tends to stick to it. Clean deck
thoroughly if you mulch wet grass.
For effective mulching, overlap mowing paths so
that the clippings are distributed evenly.

MANUFACTURER’S LIMITED WARRANTY FOR:

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.
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, commercial 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.
Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear part or component 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 components 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.
HOW TO OBTAIN SERVICE: Warranty service is available,
WITH PROOF OF PURCHASE THROUGH YOUR LOCAL
AUTHORIZED SERVICE DEALER. To locate the dealer in
your area, please check for a listing in the Yellow Pages or
contact the Customer Service Department of MTD PRODUCTS INC by calling 1-800-800-7310 or writing to P.O. Box
368022, Cleveland, Ohio 44136-9722.
This limited warranty does not provide coverage in the
following cases:
a. The engine or component parts thereof. These items
carry a separate manufacturer’s warranty. Please refer
to the applicable manufacturer’s warranty on these
items.
b. Log splitter pumps, valves and cylinders have a separate one year warranty.

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.
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 distribution.
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 Warranty, 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.)
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 services, for transportation or for related expenses, or for
rental expenses to temporarily replace a warranted
product. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
exclusion or limitation may not apply to you.)
In no event shall recovery of any kind be greater than the
amount of the purchase price of the product sold. Alteration
of the safety features of the product shall void this Warranty. 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.
This limited warranty shall not extend to anyone other than
the original purchaser, original lessee or the person for
whom it was purchased as a gift.
How State Law Relates to this Warranty: This limited
warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.
