AC WARNING ^
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2V2 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.
CONTENTS OF HARDWARE PACK
Remove this sheet from your owner’s manual and lay the hardware on the illustration for identification purposes.

AND/OR PROPERTY OF YOURSELF AND OTHERS, READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE AHEMPTING
TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN
YOU SEE THIS SYMBOL-
A
HEED ITS WARNING.
DANGER
AC
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. If you violate any of these rules, you may cause serious injury to yourself or others.
A
TRAINING
Read this owner’s guide carefully in its entirety before attempting
to assemble or operate this machine. 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.
2. Your rotary mower is a precision piece of power equipment, not
a plaything. Therefore, exercise extreme caution at ail times.
3. Never allow children to operate a power mower. Only persons well
acquainted with these rules of safe operation should be allowed
to use your mower.
4. 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 in
jury. Although the area of operation should be completely cleared
of foreign objects, an object may have been overlooked and could
be accidently thrown by the mower in any direction and cause
serious personal injury to the operator or any others allowed in
the area.
PREPARATION
1. Thoroughly inspect the area where the equipment is to be used.
Remove all stones, sticks, wire, bones and other foreign objects
which could be picked up and thrown by the mower in any direc
tion and cause serious personal injury to the operator or any others
allowed in the area.
2. Always wear safety glasses or eye shields 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.
3. Wear sturdy, rough-soled work shoes and close-fitting slacks and
shirts to avoid entanglement in the moving parts. Never operate
a unit in bare feet, sandals, or sneakers.
4. Check the fuel before starting the engine. Gasoline is an extreme
ly flammable fuel. Do not fill the gasoline tank indoors, while the
engine is running, or until engine has been allowed to cool for
two minutes after running. Replace gasoline cap securely and wipe
off any spilled gasoline before starting the engine as it may cause
a fire or explosion,
5. Disengage the self-propelled mechanism or drive clutch on units
so equipped before starting the engine,
6. 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.
7. Never attempt to make a wheel or cutting height adjustment while
the engine is running.
8. Never operate the equipment 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. Mow only in daylight
or in good artificial light.

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, prevent
ing 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. Blade speed
should be adjusted to the condition of the lawn.
The best mowing pattern is one that allows the clippings
to discharge towards the uncut part of the lawn. This
permits recutting of the clippings to further pulverize
them. When cutting high weeds, discharge towards cut
portion, then recut at right angles to first direction.
For best results, cut off one-third or less of the total
length of the grass. 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 bagging the cut grass.

TROUBLE SHOOTING
Refer to page 13 of this manual for trouble shooting
information.
CUTTING BLADE
When removing the cutting blade for sharpening or
replacement, protect hands by using heavy glovos or
a rag to grasp the cutting blade. Remove the bolt and
bell washer which hold the blade and adapter tci the
engine crankshaft. Remove the blade and adapter from
the crankshaft.
If the blade or blade adapter needs replacing, remove
the two small bolts, lock washers and nuts which hold
the blade to the adapter.
A
When sharpening the blade, follow the original angle
of grind as a guide, it is extremely important that i ?ach
cutting edge receives an equal amount of grindir g to
prevent an unbalanced blade. An unbalanced bladiî will
cause excessive vibration when rotating at high spe eds,
may cause damage to the mower and could break,
causing personal injury.
It is recommended that the blade always be removed
from the adapter for the best test of balance.
The blade can be tested by balancing it on a round : ¡haft
screwdriver. Remove metal from the heavy side until
it balances evenly.
Before reassembling the blade and the blade adc pter
to the unit, lubricate the engine crankshaft and the i iner
surface of the blade adapter with light oil. LubriCc.ting
the bolt holes, bolts and inner surface of the nuts with
light oil is also recommended. A 4 oz. plastic bott e of
light oil lubricant is available. Order part number
737-0170. Engine oil may also be used.
When replacing the blade, be sure to install the biade
with the side of the blade marked “Bottom” (or with
part number) facing the ground when the mower is in
the operating position.
ing any repairs or maintenance.
WARNING: Periodically inspect the blade
adapter for cracks, especially if you s :rike
a foreign object. Replace when necessary.
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
cause an uneven discharge of grass clippings at the
next cutting.
The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool (make certain the
spark piug wire is disconnected).
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.

ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser
viced. 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 recom
mended 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 per
mit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,
dirt and combustible debris from muffler area.
OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
1. Clean and lubricate mower thoroughly as de
scribed in the lubrication instructions.
2. Refer to engine manual for correct engine storage
instructions.
3. Coat mower’s cutting blade with chassis grease
to prevent rusting.
4. Store mower in a dry, clean area.
Blade Mounting Torque
