SECTION 1: 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 this operator’s manual carefully in its entirety
before attempting to assemble this machine. Read,
understand, and follow all instructions on the
machine and in the manual(s) before operation. Be
completely familiar with the controls and the proper
use of this machine before operating it. Keep this
manual in a safe place for future and regular
reference and for ordering replacement parts.
• Your rotary mower is a precision piece of power
equipment, not a plaything. Therefore, exercise
extreme caution at all times. Your unit has been
designed to perform one job: to mow grass. Do not
use it for any other purpose.
• Never allow children under 14 years old to operate
a power mower. Children 14 years old and over
should only operate mower under close parental
supervision. Only responsible individuals who are
familiar with these rules of safe operation should
be allowed to use your mower.
• Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine
when they are in the vicinity of your mower to help
prevent blade contact or thrown object injury.
Although the area of operation should be
completely cleared of foreign objects, an object
may have been overlooked and could be
accidentally thrown by the mower in any direction
and cause serious personal injury to the operator
or any others allowed in the area.
• Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Shirts and pants that cover
the arms and legs and steel-toed shoes are
recommended. Do not wear loose fitting clothes or
jewelry. They can be caught in moving parts.
Never operate a unit in bare feet, sandals, slippery
or light weight (e.g. canvas) shoes.
• Always wear safety glasses or safety goggles
during operation or while performing an adjustment
or repair, to protect eyes from foreign objects that
may be thrown from the machine in any direction.
• Thoroughly inspect the area where the equipment
is to be used. Remove all stones, sticks, wire,
bones, toys and other foreign objects which could
be picked up and thrown by the mower in any
direction and cause serious personal injury to the
operator or any others allowed in the area. Plan
your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like.
To help avoid a thrown objects injury, keep
children, bystanders and helpers at least 75 feet
from the mower while it is in operation.
• Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening at all times
as the rotating blade can cause injury.
• Many injuries occur as a result of the mower being
pulled over the foot during a fall. Do not hang on to
the mower if you are falling; release the handle
immediately.
• Never pull the mower toward you while you are
walking. If you must back the mower away from a
wall or obstruction first look down and behind, and
then follow these steps:
• Step back from the mower to fully extend your
arms.
• Be sure you are well balanced with sure
footing.
• Pull the mower back slowly, no more than half
way toward you.
• Repeat these steps as needed.
• Do not operate the mower while under the
influence of alcohol or drugs.
3
• Do not engage the self-propelled mechanism on
units so equipped while starting engine.
• The blade control handle is a safety device. Never
attempt to bypass its operation. Doing so makes
the safety device inoperative and may result in
personal injury through contact with the rotating
blade. The blade control handle must operate
easily in both directions and automatically return to
the disengaged position when released.
• Never operate the mower in wet grass. Always be
sure of your footing. A slip and fall can cause
serious personal injury. Keep a firm hold on the
handle and walk, never run. If you feel you are
losing your footing, RELEASE THE BLADE
CONTROL HANDLE IMMEDIATELY and the
blade will stop rotating within three seconds.
• Mow only in daylight or good artificial light.
• Stop the blade when crossing gravel drives, walks
or roads.
• If the equipment should start to vibrate abnormally,
stop the engine and check immediately for the
cause. Vibration is generally a warning of trouble.
• Shut the engine off and wait until the blade comes
to a complete stop before removing the grass
catcher or unclogging the chute. The cutting blade
continues to rotate for a few seconds after the
engine is shut off. Never place any part of the body
in the blade area until you are sure the blade has
stopped rotating.
• Never operate mower without proper guards, grass
catcher, plates or other safety protective devices in
place.
• Muffler and engine become hot and can cause a
burn. Do not touch.
• Only use accessories approved for this machine
by the manufacturer. Read, understand, and follow
all instructions provided with the approved
accessory.
• If situations occur which are not covered in this
manual, use care and good judgment. Contact
your dealer for assistance. Telephone 1-800-8007310 for the name of your nearest dealer.
2. SLOPE 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
degrees as shown on the slope gauge, do not operate this
unit on that area or serious injury could result.
DO:
• Mow across the face of slopes; never up and
down. Exercise extreme caution when changing
direction on slopes.
• Watch for holes, ruts, hidden objects, or bumps.
Tall grass can hide obstacles.
• Always be sure of your footing. A slip and fall can
cause serious personal injury. If you feel you are
losing your balance release the blade control
handle immediately and the blade will stop in less
than 3 seconds.
DO NOT:
• Do not mow near drop-offs, ditches or
embankments. The operator could lose footing or
balance.
• Do not mow slopes greater than 15 degrees as
shown on the slope gauge.
• Do not mow on wet grass. Reduced footing could
cause slipping.
3. CHILDREN
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the mower and the mowing activity. Never assume that
children will remain where you last saw them.
• Keep children out of the mowing area and under
the watchful care of a responsible adult other than
the operator.
• Be alert and turn mower off if a child enters the
area.
• Before and while moving backwards, look behind
and down for small children or other objects.
• Never allow children under age 14 to operate the
mower. Children 14 years of age and above
should read and understand the operation
instructions and safety rules in this manual.
• Use extreme care when approaching blind
corners, shrubs, trees, or other objects that may
obscure your vision of a child or 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 gasoline container.
• Never remove gas cap or add fuel while the engine
is running. Allow engine to cool at least two
minutes before refueling.
• Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it
may cause a fire or explosion.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel machine indoors because flammable
vapors will accumulate in the area.
• Never store the machine or fuel container inside
where there is an open flame or spark such as a
gas water heater, space heater, or furnace.
• Never run an engine inside a closed area.
4
• To reduce fire hazard, keep mower free of grass,
leaves, or other debris build-up. Clean up oil or
fuel spillage. Allow mower 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., bent,
cracked or worn). Replace with blade which meets
original equipment specifications listed in this
manual.
• 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.
• 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 starting and operating
the mower.
• Never attempt to make a wheel or cutting height
adjustment while the engine is running.
• Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For
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 them.
• Do not change the engine governor setting or
overspeed the engine. Excessive engine speeds
are dangerous.
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.
Figure 1 Safety Labels Found On Lawn Mower
SLOPE GAUGE
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.
Operate RIDING mowers up and down slopes, never across the face of slopes.
Operate WALK-BEHIND mowers across the face of slopes, never up and down slopes.

EACH TIME BEFORE YOU START YOUR MOWER
• Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug wire is
fastened securely over the metal tip on the spark plug.
• Check for proper drive clutch operation using the NEUTRAL ADJUSTMENT TEST.
NEUTRAL ADJUSTMENT TEST
To perform the NEUTRAL ADJUSTMENT TEST answer the following questions.
• With the drive clutch control released, push mower forward and pull it backward. Does it move freely?
• Squeeze the drive clutch control and pull the mower backward. Do the rear wheels lock (not turn)?
• Is the drive clutch control cable free of kinks or sharp bends?
If you answered “yes” to all three questions, your mower passed the test and you can start your mower. If
you answered “no” to any of the three questions, you need to go through the DRIVE CLUTCH CONTROL
ADJUSTMENT found in the ADJUSTMENTS section.
TO START ENGINE AND ENGAGE BLADE
• Move the throttle control lever all the way forward.
• Prime engine as instructed in the separate engine manual.
• Stand behind the unit, squeeze and hold the blade control handle against the upper handle.
• Grasp starter handle and pull rope out slowly until engine reaches start of compression cycle (rope will
pull slightly harder at this point). Let the rope rewind slowly.
• Pull rope with a rapid, continuous, full arm stroke. Keep a firm grip on starter handle. Return it slowly to
the rope guide.

operated at full throttle.)
NOTE: If any problems are encountered, refer to the TROUBLE SHOOTING Section of this manual.
TO STOP ENGINE AND BLADE
• Release the blade control handle to stop the engine and blade.
WARNING: The blade continues to rotate for a few seconds after the engine is shut off.
USING YOUR ROTARY MOWER
Be sure that lawn is clear of stones, sticks, wire, or other objects which could damage the lawn mower or
engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal
injury to the operator and others.
For the best results, do not cut wet grass because it tends to stick to the underside of the mower, preventing
proper discharge of grass clippings, and could cause you to slip and fall. New grass, thick grass or wet grass
may require a narrower cut.
For a healthier lawn, never cut off more than one-third of the total length of the grass. Your lawn should be
cut in the fall as long as there is growth.
This mower is designed to be operated at full throttle to give you the best cut and do the most effective job of
mowing or mulching.
WARNING: If you strike a foreign object, stop the engine. Remove wire from spark plug,
thoroughly inspect the mower for any damage, and repair the damage before restarting and
operating the mower. Extensive vibration of the mower during operation is an indication of damage.
The unit should be promptly inspected and repaired.

mower more than 90 degrees and do not leave the mower tipped for any length of time. Oil can drain into
the upper part of the engine causing a starting problem.
ENGINE
Refer to the separate engine manual for all engine maintenance instructions.
• Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow
instructions carefully.
• Service air cleaner every 25 hours under normal conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.
• The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is
recommended at the start of each mowing season; check engine manual for correct plug type and gap
specifications.
• Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean
to permit proper air circulation which is essential to engine performance and life. Be certain to remove
all grass, dirt and combustible debris from muffler area.
16
DECK
The underside of the mower deck should be cleaned after each use to prevent a buildup of grass clippings,
leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may
prevent proper mulching, discharge or bagging.
The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark
plug wire is disconnected).
CUTTING BLADE REMOVAL, REPLACEMENT AND SHARPENING

covers units which have been operated and
maintained in accordance with the operating
instructions furnished with the unit, and which have
not been subject to misuse, abuse, commercial use,
neglect, accident, improper maintenance or
alteration.
Normal wear parts or components thereof are
subject to separate terms as noted below in the “No
Fault Ninety Day Consumer Warranty” clause.
All normal wear part failures will be covered on this

bags, rider deck wheels, seats, snow thrower skid
shoes, shave plates and tires.
How to obtain service: Warranty service is
available, with proof of purchase, through your local
authorized service dealer. To locate the dealer in

States of America, its possessions and territories,
except those sold through MTD PRODUCTS INC’s

state to state. Certain disclaimers are not allowed in
