MAINTENANCE
V-BELTS
Check V-belts for deterioration and wear after 100
hours of operation and replace if necessary. The belts
are not ad just able. Re place belts if they begin to slip
from wear.
TRANSAXLE COOLING
The transmission fan and cooling fins should be kept
clean to assure proper cooling.
Do not attempt to clean fan or transmission while engine
is running or while the transmission is hot. To prevent
pos si ble damage to seals, do not use high pressure
water or steam to clean transaxle.
• Inspect cooling fan to be sure fan blades are intact
and clean.
• Inspect cooling fins for dirt, grass clippings and
other materials. To prevent damage to seals, do
not use compressed air or high pressure sprayer
to clean cooling fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fluid main te -
nance is not required for the life of the transaxle. Should
the transaxle ever leak or require servicing, contact
your near est au tho rized ser vice center/department.

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.
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.
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.

• Rinse the battery with plain water and dry.
• Clean terminals and battery cable ends with wire
brush until bright.
• Coat terminals with grease or petroleum jelly.
• Reinstall battery (See “REPLACING BATTERY" in
the SERVICE AND ADJUSTMENTS section of this
man u al).
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire
brush or compressed air to re move dirt and stubborn
dried gum fibers.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See Engine Manual.
TO CHANGE ENGINE OIL (See Figs. 24 and 25)
Determine temperature range expected before oil
change. All oil must meet API service classification
SG-SL.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove oil fill cap/dipstick. Be careful not to allow
dirt to enter the engine when changing oil.
• Remove yellow cap from end of drain valve and
install the drain tube onto the fitting.

• After oil has drained completely, close and lock
the drain valve by pushing inward and turning
clockwise until the pin is in the locked position as
shown.
• Remove the drain tube and replace the cap onto
to the bottom fitting of the drain valve.
• Refill engine with oil through oil fill dipstick tube.
Pour slowly. Do not overfill. For approximate ca-
pacity see “PRODUCT SPECIFICATIONS” section
of this man u al.
• Use gauge on oil fill cap/dipstick for checking
level. Be sure dipstick cap is tightened securely
for accurate reading. Keep oil at “FULL” line on
dipstick. Tighten cap onto the tube securely when
finished.
