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 25 hours thereafter or at least once a year if the
tractor is not used for 25 hours in one year.

and after each eight (8) hours of operation. Tighten oil fill
cap/dipstick securely each time you check the oil level.
