MAINTENANCE
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor.
•
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
manual).
V-BELTS
Check V-belts for deterioration
and wear after 100 hours
of operation and replace if necessary. The belts are not
adjustable. Replace 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-
sible 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 coo!-
ing fins.
TRANSAXLE
PUMP FLUID
The transaxle was sealed at the factory and fluid mainte-
nance is not required for the life of the transaxle. Should
the transaxle ever leak or require servicing, contact your
nearest authorized service center/department.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF-SJ. Select the oil's SAE viscosity grade
according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, t0W30 etc.)
improve starting in cold weather, these multi-viscosityoils
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.
TO CHANGE ENGINE OIL (See Figs. 12 and 13)
Determine temperature range expected before oil change.
All oil must meet API service classification SF-SJ.
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.

Unlock drain valve by pushing inward and turning
counterclockwise.
To open, pull out on the drain valve.
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 capacity see
"PRODUCT SPECIFICATIONS"
section of this man-
uaL
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.
CLEAN
AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine damage from overheating. Clean with a wire brush
or compressed air to remove dirt and stubborn dried gum
fibers.
