TO CLEAN BATTERY AND TER MI NALS
Corrosion and dirt on the battery and terminals
can cause the battery to "leak" power.
1. Remove terminal guard.
2. Disconnect BLACK battery cable first
then RED bat tery cable and remove
battery from tractor.
3. Rinse the battery with plain water and
dry.
4. Clean terminals and battery cable ends
with wire brush until bright.
5. Coat terminals with grease or pe tro leum
jelly.
6. Reinstall battery (See "REPLACING
BATTERY" in the Service and Ad just-
ments section of this manual).
TRANSAXLE MAINTENANCE
Keep transaxle free from build-up of dirt and
chaff which can restrict cooling.
Do not attempt to clean transaxle while
engine is running or while the transaxle is
hot. To prevent pos si ble damage to seals,
do not use high pressure water or steam to
clean transaxle.
V-BELTS
Check V-belts for deterioration and wear after
100 hours of operation and replace if neces-
sary. The belts are not ad just able. Re place
belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with
API service classification SG-SL. Select the oil's
SAE viscosity grade according to your expected
operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption when
used above 32°F/0°C. Check your engine oil level
more frequently to avoid possible engine damage
from running low on oil.
Change the oil after every 50 hours of operation
or at least once a year if the tractor is not used
for 50 hours in one year.
Check the crankcase oil level before starting the
engine and after each eight (8) hours of operation.
Tighten oil fill cap/dipstick securely each time you
check the oil level.

TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
• Ensure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
LOWER DASH COVER REMOVAL
1. Raise hood.
2. Remove fastener from lower dash cover.
CAUTION: Remove lower dash cover care-
fully to ensure cover tabs are not broken.
3. Slide lower dash cover up to release
