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 com-
pressed 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.
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.

MAINTENANCE
ENGINE OIL FILTER
Replace the engine oil filter every season or every other oil
change if the tractor is used more than 100 hours in one
year. See engine man u al.
TO CHANGE ENGINE OIL (See Fig. 18 & 19)
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.
•
Slide oil drain extension under oil drain hole (drain hole
may be flush with or protrude from engine block side wall).
•
Make sure back face of oil drain extension is flush with
engine side wall.
• Make sure bottom lip of oil drain extension is lined up
with bottom of oil drain hole.
•
Position a container to catch oil directly under front end
of oil drain extension.
•
Slide a 1/2” (12 point) socket mounted on an extension
onto oil drain plug.
•
Loosen plug while holding the oil drain extension firmly
in place.
• Drain oil into container.
•
After oil has drained completely, reinstall oil drain plug.
(Do not tighten more than 13 Ft. Lbs.)
• Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill. For approximate capacity 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.
