Check battery case for leakage to make sure that no
damage has occurred in handling.
Dispose of excess battery acid. Neutralize acid for
disposal by adding it to four inches of water in a five
gallon plastic container. Stir with a wooden or plastic
paddle while adding baking soda until the addition of
more soda causes no more foaming.
Follow instructions on how to install battery.
CHECK DECK LEVELNESS
For best cutting results, mower housing should be properly
leveled. See "TO LEVEL MOWER HOUSING" in the

The cutting height range is approximately 1-1/4" to 3-3/4".
The heights are measured from the ground to the blade tip
with the engine not running. These heights are approximate and may vary depending upon soil conditions, height
of grass and types of grass being mowed.
•
The average lawn should be cut approximately 2-1/2
inches during the cool season and over 3 inches during
hot months. For healthier and better looking lawns,
mow often and after moderate growth.
•
For best cutting performance, grass over 6 inches in
height should be mowed twice. Make the first cut
relatively high; the second to desired height.

WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine whiie in storage. To avoid engine
problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instructions for additional information.
Never use engine or

OPERATION
ruing.
Drive so that clippings are discharged onto the area
that has been cut. Have the cut area to the right of the
machine. This will result in a more even distribution of
clippingsand more uniform cutting.
TO START ENGINE (See Fig. 7)
When starting engine for the first time or if engine has run
out of fuel, it will take extra cranking time to move fuel from
the tank to the engine.

Place motion control lever in "NEUTRAL" position.
•
•
Move attachment clutch to "DISENGAGED" position.
Movethrottle control lever to"CHOKE" position for cold
engine start. For warm engine start, move throttle
control to "FAST" position.
•
•
•
When mowing large areas, start by turning to the right
so that clippings will discharge away from shrubs,
fences, driveways, etc. After one or two rounds, mow
in the opposite direction making left hand turns until
finished (See Fig. 9).
F
Turn ignition key clockwise to "START" position and
release key as soon as engine starts. Do not run
starter continuously for more than fifteen seconds per
minute. If engine does no_ start a_er several attempts,
move throttle control to FAST position, wait a few
minutes and try again.
When engine starts, slowly move throttle control lever
to desired running speed.
Allow engine to warm up for a few minutes before
engaging motion control or attachment clutch.
FIG. 9
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32 ° F), the carburetor fuel mixture
may need to be adjusted for best engine performance. See
"TO ADJUST CARBURETOR" in the Service and Adjustments section of this manual.
•
MOWING TIPS
If grass is extremely tall, it should be mowed twice to
reduce load and possible fire hazard from dried clipdPings. Make first cut relatively high; the second to the
esired height.
Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable clumps. Allow grass to
dry before mowing.
•
Tire chains cannot be used when the mower housing
is attached to unit.
•
•
Mower should be properly leveled for best mow!,n..g
performance. See"TO LEVELMOWER HOUSING in
the Service and Adjustments section of this manual.
Use the runner on the right hand side of mower as a
guide. The blade cuts approximately an inch outside
the runner (See Fig. 8).
The left hand side of mower should be used for trim-
•
Always operate engine atfull throttle when mowing to
assure better mowing performance and proper discharge of material. Regulate ground speed by selecting a low enough gear to give the mower cutting
performance as welt as the quality of cut desired.
•
When operating attachments, select a ground speed
that will suit the terrain and give best performance of
the attachment being used.

STORAGE
Immediately prepare your tractor for storage at the end of
the season or ifthe unit will not be used for 30 days or more.
ENGINE
FUEL SYSTEM
IMPORTANT: IT lS IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING IN ESSENTIAL FUEL
SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER,
FUEL HOSE, OR TANK DURING STORAGE. ALSO,
EXPERIENCE INDICATES THAT ALCOHOL BLENDED
FUELS (CALLED GASOHOL OR USING ETHANOL OR
METHANOL) CAN ATTRACT MOISTURE WHICH LEADS
TO SEPARATION AND FORMATION OF ACIDS DURING
STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL
SYSTEM OF AN ENGINE WHILE IN STORAGE.
•
Drain the fuel tank.
CAUTION: Never store the tractor with
gasoline in the tank Inside a building
where fumes may reach an open flame
or spark, Allow the engine to cool
before storing in any enclosure.
TRACTOR
Remove mower from tractor for winter storage. When
mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Give blades
and underside of housing a good coat of grease or rust
preventative. Store in a clean, dry area.
•
Clean entire tractor (See "CLEANING" in the Maintenance section of this manual).
•
•
•
Start the engine and let it run until the fuel lines and
carburetor are empty.
•
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Use fresh fuel next season.
•
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor. Do
not drain the gas tank and carburetor if using fuel stabilizer.
Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments
section of this manual).
Lubricate as shown in the Maintenance section of this
manual.
Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving partsfordamage, breakage
and wear. Replace if necessary.
ENGINE OIL
Drain oit (with engine warm) and replace with clean engine
oil. (See "ENGINE" in the Maintenance section of this
manual).
Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
BATTERY
CYLINDERS
•
Fully charge the battery for storage.
•
Remove spark plug(s).
•
After a period of time in storage, battery may require
recharging.
•
Pour one ounce of oil through spark plug hole(s) into
cylinder.
•
To help prevent corrosion and power leakage during
long periods of storage, battery cables should be
disconnected and batterycleaned thoroughly (see "TO
CLEAN BATTERY AND TERMINALS" in the Maintenance section of this manual).
•
Turn ignitionkeyto"START"
to distribute oil.
•
Replace with new spark plug(s).
After cleaning, leave cables disconnected and place
cables where they cannot come in contact with battery
terminals.
OTHER
•
Do not store gasoline from one season to another.
Be sure battery drain tube is securely attached to drain
in battery tray.
•
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
°
If possible, store your unit indoors and cover it to give
protection from dust and dirt.
