TRACTOR STORAGE
If Tractor is to be idle for an extended period of
time, it should be prepared for storage.
1. Store Tractor in a dry area where it will be
protected from weather.
2. Open fuel shut-off valve, No. 1, Fig. 20, and
drain all fuel from tank, close valve. Start engine
and run until it runs out of fuel.
3. Remove spark plug, No. 4, Fig. 12, and put a
tablespoon of engine oil into spark plug hole. Turn
engine over two or three times with starter and regap
spark plugs to .035" and replace. Leave spark plug
wires disconnected.
4. Lubricate fully as described in "Lubrication"
Section.
5. Remove battery, clean case and terminals
thoroughly. Coat terminals with a thin coating of
petroleum jelly. Charge battery and store in a cool
dry place. Do not store on a cement floor. Recharge
at least monthly while in storage.
REMOVING TRACTOR
FROM STORAGE
1. Install fully charged battery, placing boot
over positive terminal.
2. Clean or replace air filter element. Refer to
"Maintenance" Section for procedure.
3. Check crankcase oil level. If needed, drain
after running engine until warm, and refill.
4. Move Tractor outside and fill fuel tank. Con¬
nect spark plug wires and run engine several min¬
utes before placing Tractor under load.
5. Check transmission oil level. Fill using pro¬
cedure prescribed in "Lubrication" Section.
6. Check tire pressures. Refer to "Maintenance"
Section for correct pressures.
TROUBLE-SHOOTING
NOTE: Neutral return switch and front PTO
switch must make a circuit when pedal is down
and rear PTO lever is in disengaged position.
Seat Switch makes a circuit when seat is "Up"
and has an open circuit when operator is seated.
