NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cotd weather,
they will result in increased oil consumption
when used above 32°F/0°C.
Check your
engine oil level more frequently
to avoid
possible engine damage from running low
on oil.
Change the oil after every 50 hours of op-
eration or at least once a year if the tractor
is not used for 50 hours in one year.
Checkthe 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.
TO CHANGE ENGINE OiL

temperature
range
expected
before oil change.

service classification
SG-SL.
1. Ensure tractor is on level surface.
