ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SForSG. 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, these multi-viscosity oils
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 the first two hours of operation and
every 50 hours thereafter 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/dipsiick securely each time you check the oil level.

TO CHANGE ENGINE OIL (See Figs. 14 and 15)
Determine temperature range expected before oil change.
All oil must meet API service classification SF or SG,
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 drain plug,
After oil has drained completely, replace oil drain plug
and tighten securely.
Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill For approximate capacity see
“PRODUCT SPECIFICATIONS” on page 3 of this
manual.
Use gauge on oil fill cap/dipstick for checking level.
Insert dipstick into the tube and rest the oil fill cap on the
tube. Do not thread the cap onto the tube when taking
reading Keep oil at “FULL” line on dipstick. Tighten
cap onto the tube securely when finished.
