OPERATION
FIG. 11
TOWING CARTS AND OTHER ATTACH-
MENTS
Tow only the attachments that are recommended by and
comply with specifications of the manufacturer of your trac-
tor. Use common sense when towing. Too heavy of a load,
while on a slope, is dangerous. Tires can lose traction with
the ground and cause you to lose control of your tractor.
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine inyour tractor has been shipped, from the
factory, already filled with summer weight oil.
Check engine oilwith tractor on level ground.
Remove oilfillcap/dipstick and wipe clean, reinsert the
dipstick 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 ofthis manual).
To change engine oil, see the Maintenance section in
this manual.
ADD GASOLINE
Fill fuel tank to bottom of filler neck. Do not overfill.
Use fresh, clean, regular unleaded gasoline with a
minimum of 87 octane. (Use of leaded gasoline will
increase carbon and lead oxide deposits and reduce
valve life). Do not mix oilwith gasoline. Purchase fuel
in quantities that can be used within 30 days to assure
fuel freshness.
[A
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can at-
tract 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 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 carburetor
cleaner products in the fuel tank or permanent
damage may occur.
TO START ENGINE (See Fig. 8)
When starting the engine for the first time or ifthe engine
has run out offuel, it willtake extra cranking time to move
fuel from the tank to the engine.
Besure freewheelcontrolisinthetransmissionengaged

Sit on seat in operating position, depress clutch/brake
pedal and set parking brake.
Place motion control lever in neutral (N) position.
Move attachment clutch to "DISENGAGED" position.
Move throttle control to fast position
Pull choke control out for a cold engine start attempt.
Fora warm engine startattempt the choke controlmay
not be needed.
NOTE: Before starting, read the warm and cold starting
procedures below.
Insert key into ignition and turn 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. Ifthe engine does not start
after several attempts, push choke control in, wait a
few minutes and try again. Ifengine stilldoes notstart,
pull the choke control out and retry.
WARM WEATHER STARTING (50 ° F and above)
When engine starts, slowly push choke control in until
the engine begins to run smoothly. If the engine starts
to run roughly, pull the choke control out slightly for a
few seconds and then continue to push the control in
slowly.
The attachments and ground drive can now be used. If
the engine does not accept the load, restart the engine
and allow it to warm up for one minute using the choke
as described above.
COLD WEATHER STARTING (50° F and below)
When engine starts, slowly push choke control in until
the engine begins to run smoothly. Continue to push
the choke control in small steps allowing the engine to
accept small changes inspeed and load, until the choke
control is fully in. If the engine starts to run roughly, pull
the choke control out slightly for a few seconds and
then continue to push the control in slowly. This may
require an engine warm-up period from several seconds
to several minutes, depending on the temperature.
