TE,MPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30, 10VV30 etc.,)
improve starting in cold weather, these multi-viscosity oils
wilt 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/dipstick securely each time you check the oil level
