TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 oi! 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 Fig. 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.
o After oil has drained completely, replace oil drain plug
and tighten securely.
o 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. Be
sure dipstick is in all the way for accurate reading.
Keep oil at "FULL" line on dipstick.

AIR FILTER (See Fig. 16)
Your engine will not run properly using a dirty air filter.
Clean the foam pre-cleaner after every 25 hours of opera-
tion or every season. Service paper cartridge every 100
hours of operation or every season, whichever occurs first.
Service air cleaner more often under dusty conditions.
