The heights are measured from the ground to the blade tip
with the engine not running. These heights are approx^
mate 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 while in storage To avoid engine
problems, the fuel system should be emptied before stor
age 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 Iristructions for additional information. Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.
CAUTION: Fill to bottom of gas tank

may need to be adjusted for best engine performance. See
“TO ADJUST CARBURETOR“ in the Service and Adjust
ments section of this manual,
MOWING TIPS
• Tire chains cannot be used when the mower housing
is attached to unit.
• Mower should be properly leveled for best mowing
performance. See "TO LEVEL MOWER 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
ming.
•
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
clippings and more uniform cutting
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).
If grass is extremely tall, it should be mowed twice to
reduce load and possible fire hazard from dried clip
pings. Make first cut relatively high; the second to the
desired height
Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable dumps. Allow grass to
dry before mowing.
Always operate engine at full throttle when mowing to
assure better mowing performance and proper dis
charge of material. Regulate ground speed by select
ing a low enough speed to give the mower cutting
performance as well 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.

GENERAL RECOIVilVlENDATIONS
The warranty on this vehicle does not cover items that have
been subjected to operator abuse or negligence. To
receive full value from the warranty, operator must maintain
unit as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your unit.
All adjustments in the Service and Adjustments section of
this manual should be checked at least once each season
• Once a year you should replace the spark plug, clean
or replace air filter, and check blades and belts for
wear. A new spark plug and clean air^ filter assure
proper air-fue! mixture and help your engine run better
and last longer.
BEFORE EACH USE
• Check engine oil level.
• Check brake operation.
• Check tire pressure.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated (See "LUBRICATION CHART").
LUBRICATION CHART
IMPORTANT - Do not oil or grease the pivot points which have
special nylon bearings, Viscous lubricants will attract dust and dirt
that will shorten the life of the self-lubricating bearings. If you feel
they must be lubricated, use only a dry, powdered graphite type
lubricant sparingly.

MAINTENANCE
TRACTOR
Always observe safety rules when performing any mainte
nance.
TIRES
• Maintain proper air pressure in all tires (See "PROD
UCT SPECIFICATIONS" on page 3 of this manual)..
» Keep tires free of gasoline, oil, or insect control chemi
cals which can harm rubber,
• Avoid stumps, stones, deep ruts, sharp objects and
other hazards that may cause tire damage.
BLADE CARE
For best results mower blades must be kept sharp. The
blades can be sharpened with a file or on a grinding wheel.
We suggest they be sharpened or replaced after every 25
hours of mowing Check blades more often if mowing in
sandy conditions ,
■ Do not attempt to sharpen blades while they are on the
mower.
• Replace bent or damaged blades
BLADE REMOVAL (See Fig. 10)
• Raise mower to highest position to allow access to
blades.
• Remove hex bolt, lockwasher and flat washer securing
blade
• Install new or resharpened blade with trailing edge up
towards deck as shown
• Reassemble hex bolt, iockwasher and flat washer in
exact order as shown.
• Tighten bolt securely (30-35 Ft. Lbs. torque).
IMPORTANT: BLADE BOLT IS GRADE 5 HEATTREATED,
TO SHARPEN BLADE (See Fig. 11)
Care should be taken to keep the biade balanced. An
unbalanced blade will cause excessive vibration and even
tual damage to mower and engine.
• The blade can be sharpened with a file or on a grinding
wheel. Do not attempt to sharpen white on the mower.
• To check blade balance, drive a nail into a beam or wall.
Leave about one inch of the straight nail exposed.
Place center hole of blade over the head of the nail, if
blade is balanced, it should remain in a horizontal
position. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.
FIG. 11
BATTERY (See Fig. 12)
Your unit has a battery charging system which is sufficient
for normal use. However, periodic charging of the battery

FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING IN ESSEN
TIAL 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 STOR
AGE. ACIDIC GAS CAN DAMAGE THE
FUEL SYSTEM OF AN ENGINE WHILE

• Drain the fuel tank,
* 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 stor
age. 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
ENGINE OIL
