The direction and speed of movement is controlled by the
gearshift lever
• Start tractor with clutch/brake pedal depressed and
gearshift lever in "NEUTRAL" position
• Move gearshift lever to desired position
• Slowly release clutch/brake pedal to start movement.
The position of the attachment lift lever determines the
cutting height
• Grasp lift lever
- Press plunger with thumb and move lever to desired
position
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 approxi
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 coo! 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

TO TRANSPORT
• Raise attachment lift control to highest position.
• When pushing or towing your unit, be sure gearshift
lever is in "NEUTRAL" position.
» Do not push or tow unit at more than five (5) MPH
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL (See Fig. 16)
• The engine in your unit has been shipped, from the
factory, already filled with summer weight oil,,
• Check engine oil with unit on level ground.
■ Remove oil fill dipstick and wipe clean, replace and
screw cap tight, wait for a few seconds, remove and
read oil level. If necessary, add oil until "FULL" mark
on dipstick is reached. Do not overfill,
• For cold weather operation you should change oil for
easier starting (see "OIL VISCOSITY CHART" in the
Maintenance section of this manual).
' To change engine oil, see the Maintenance section in
this manual.
ADD GASOLINE
• Fili fuel tank. Use fresh, clean, regular unleaded gaso
line, (Use of leaded gasoline will increase carbon and
lead oxide deposits and reduce valve life).
IMPORTANT: WHEN OPERATING IN TEMPERA
TURES BELOW32°F(0“C), USE FRESH,
CLEAN WINTER GRADE GASOLINE TO
HELP INSURE GOOD COLD WEATHER
STARTING.
WARNING: Experience indicates that alcohol biended
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 fue! lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc
tions for additional information. Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.
Choose the slowest speed before starting up or down
hills.
Avoid stopping or changing speed on hills.
If slowing Is necessary, move throttle control lever to
slower position.

OPERATION
TO START ENGINE (See Fig. 7)
When starting engine for the first time or if engine has
run out of fuei, it will take extra cranking time to move
fuel from the tank to the engine
' Depress the clutch/brake pedal and set the parking
brake-
• Place gearshift lever in "NEUTRAL" position.
• Move attachment clutch to "DISENGAGED" position
• Move throttle control lever to "CHOKE" position for
cold engine start For warm engine start, move
throttle contro! to "FAST" position.
• 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 not start after several
attempts, move throttle control to "FAST" position,
wait a few minutes and try again
• When engine starts, move throttle control to desired
position.
• Allow engine to warm up for a few minutes before
engaging drive or attachment clutch.
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
• Tire chains cannot be used when the mower hous
ing 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 distri
bution of clippings and more uniform cutting.
When mowing large areas, start by turning to the
right so that clippings wiil 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
clippings. Make first cut relatively high; the second
to the desired height '
Do not mow grass when it is wet. Wet grass wiil
piug mower and leave undesirable dumps Allow
grass to dry before mowing
Always operate engine at lull 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 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.

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,

• Reassemble hex bolt, locNwasher and flat washer in
exact order as shown.
• Tighten bolt securely (30-35 Ft. Lbs. torque).
IMPORTANT; BLADE BOLT IS GRADE 5 HEATTREATEO.
TO SHARPEN BLADE (See Fig. 11)
Care should be taken to keep the blade 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 while on the mower
• Tocheck blade balance, drive a nail into a beam or wall
Leave about one inch of the straight nail exposed.

the season or if the unit will not be used for 30 days or more.
CAUTION: Never* store the tractor with
gasoline in the tank inside a buliding
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 thor
oughly, remove ail dirt,^ grease, leaves, etc. Give biades
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 Mainte
nance section of this manual).
• Inspect and replace belts, if necessary (See belt re
placement 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 parts for damage, breakage
and wear. Replace if necessary.
■ Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
— A'i"T p DY
f 1 Im li 1
• Fully charge the battery for storage,
• After a period of time In storage, battery may require
recharging,
• To help prevent corrosion and power leakage during
long periods of storage, battery cables should be
disconnected and battery cleaned thoroughly (see "TO
CLEAN BATTERY AND TERMINALS" in the Mainte
nance section of this manual).
• After cleaning, leave cables disconnected and place
cables where they cannot come in contact with battery
terminals,
• Be sure battery drain tube is securely attached to drain
in battery tray.
• 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 mini
mizing 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.
ENGINE OIL
