BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine in your tractor has been
shipped, from the factory, already filled
with summer weight oil.
1. Check engine oil with tractor on level
ground.
2. Unthread and remove oil fill cap/
dipstick; wipe oil off. Reinsert the
dipstick into the tube and rest oil fill
cap on the tube. Do not thread the cap
onto the tube. 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 the
oil viscosity chart in the Maintenance
section of this manual).
To change engine oil, see the Mainte-
nance section in this manual.
ADD GASOLINE
Fill fuel tank to bottom of tank 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 oil
with gasoline. Purchase fuel in quanti-
ties that can be used within 30 days to
assure fuel freshness.
AI_,CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT: When operating in tempera-
tures below 32°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
attract moisture which leads to separa-
tion 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
When starting the engine for the first time
or if the engine has run out of fuel, it will
take extra cranking time to move fuel from
the tank to the engine.
1. Be sure freewheel control is in the
transmission engaged position.
2. Sit on seat in operating position,
depress clutch/brake pedal and set
parking brake.
3. Place motion control lever in neutral
(N) position.
4. Move attachment clutch to disengaged
position.
5. Move throttle control to fast position
6. Pull choke control out for a cold engine start
attempt. For a warm engine start attempt
the choke control may not be needed.
NOTE: Before starting, read the warm and
cold starting procedures below.
7. 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. If the engine does
not start after several attempts, push
choke control in, wait a few minutes and
try again. If engine still does not start, pull
the choke control out and retry.
WARM WEATHER STARTING (50 ° F and
above)
8. 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)
8. 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 en-
gine to accept small changes in speed
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.
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weather,
the transmission should be warmed up as
follows:
1. Be sure the tractor is on level ground.
2. Place the motion control lever in
neutral. Release the parking brake and
let the clutch/brake slowly return to
operating position.
