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.
This machine 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 this
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. Only responsible individuals who are familiar with
these safe operation rules should use this machine.
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 tripped over or
picked up and thrown by the blade. Thrown objects can
cause serious personal injury. Plan your mowing pattern
to avoid discharge of material toward roads, sidewalks,
bystanders and the like. Also, avoid discharging material
against a wall or obstruction which may cause
discharged material to ricochet back toward the operator.
To help avoid blade contact or a thrown object injury, stay
in the operator zone behind the handles and keep
bystanders, helpers, children and pets at least 75 feet
from the machine while it is in operation. Stop machine if
anyone enters the area.
Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair to
protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Shirts and pants that cover the arms
and legs and steel-toed shoes are recommended. Never
operate this machine in bare feet, sandals, slippery or
light weight (e.g. canvas) shoes.

Do not put hands or feet near rotating parts or under the
cutting deck. Contact with the blade can amputate hands
and feet.
A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
Many injuries occur as a result of the mower being pulled
over the foot during a fall caused by slipping or tripping.
Do not hold on to the mower if you are falling; release the
handle immediately.
Never pull the mower back toward you while you are
walking. If you must back the mower away from a wall or
obstruction, first look down and behind to avoid tripping
and then follow these steps:
a. Step back from the mower to fully extend your
arms.
b. Be sure you are well balanced with sure footing.
c. Pull the mower back slowly, no more than half way
toward you.
d. Repeat these steps as needed.
Do not operate the mower while under the influence of
alcohol or drugs.
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. If you feel you are losing your footing, release the
blade control handle immediately and the blade will stop
rotating within three seconds.
Mow in daylight or good artificial light. Walk, never run.
Stop the blade when crossing gravel drives, walkways
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

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. They do not understand the
dangers. Never assume that children will remain where you
last saw them.
1. Keep children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
2. Be alert and turn mower off if a child enters the area.
3. Before and while moving backwards, look behind and
down for small children.
4. Use extreme care when approaching blind corners,
doorways, shrubs, trees, or other objects that may
14.
15.
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.
Use only an approved gasoline container.
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.
If possible, 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.
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.
Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
Never fuel machine indoors because flammable vapors
will accumulate in the area.
Never remove gas cap or add fuel while the engine is hot
or running. Allow engine to cool at least two minutes
before refueling.
Never over fill fuel tank. Fill tank to no more than ½ inch
below bottom of filler neck to provide space for fuel
expansion.
Replace gasoline cap and tighten securely.
If gasoline is spilled, wipe it off the engine and
equipment. Move unit to another area. Wait 5 minutes
before starting the engine.
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.
To reduce fire hazard, keep mower free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Allow a mower to cool at least 5 minutes before storing.
General Service:

Check the blade and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect blade
for damage (e.g., bent, cracked, worn) Replace blade
with the original equipment manufacture’s (O.E.M.) blade
only, listed in this manual. “Use of parts which do not
meet the original equipment specifications may lead to
improper performance and compromise safety!”
Mower blades are sharp and can cut. Wrap the blade or
wear gloves, and use extra caution when servicing them.
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, disconnect
the spark plug wire and ground against the engine.
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, discharge cover, and trail
shield 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!”
10. Do not change the engine governor setting or overspeed
the engine. The governor controls the maximum safe
operating speed of the engine.
11. Maintain or replace safety and instruction labels, as
necessary.
12. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the
environment.

Using as Mulcher
completely before doing any work on the
mower or to remove the grass catcher.
For mulching grass, remove the grass catcher from the
mower. The rear discharge opening should be closed.
•
Using Rotary Mower
•
WARNING: Never operate your mower
without either the rear door or the entire grass
catcher assembly firmly secured.
•
Be sure that lawn is clear of stones, sticks, wire, or
other objects which could damage lawn mower or
engine. Such objects could be accidentally thrown
by the mower in any direction and cause serious
personal injury to the operator and others.
For effective mulching, do not cut wet grass
because it tends to stick to the underside of the
deck, preventing proper mulching.
New or thick grass may require a narrower cut. The
ground speed should be adjusted to the condition
of the lawn. If mowing has been delayed and the
grass has been allowed to grow in excess of 4",
mulching is not recommended. Mow using the
grass bag to reduce the grass height to 3-1/4"
maximum before mulching.
Bagging Grass Clippings
You can use the grass catcher bag to collect clippings
while you are operating the mower.
WARNING: If the mower strikes 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.
•
For a healthy lawn, never cut more than one-third of
the total length of the grass at any one cutting.
This mower is set at full throttle for best
performance.
•
For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings.
•
Attach grass catcher following instructions on page

When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receive an equal amount of
grinding to prevent an unbalanced blade. An
unbalanced blade will cause excessive vibration
when rotating at high speeds, and may cause
damage to the mower and/or personal injury.
•
•
•
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy
side until it balances evenly. It is recommended that
the blade always be removed from the adapter for
the best test of balance.
Before reassembling the blade and the blade
adapter to the unit, lubricate the engine crankshaft
and the inner surface of the blade adapter with light
oil (or engine oil). Lubricating the bolt holes, bolts
and inner surface of the nuts is also recommended.
Install the blade adapter on the crankshaft with the
“star” away from the engine. Place the blade with
the side marked bottom (or with part number) facing
away from the adapter. Align the blade bell support
over the blade with the tabs in the holes of the
blade and insert the hex bolt. Tighten the hex bolt to
the torque listed here.
