TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils
(5W30, IOW30 etc.) improve starting in
cold weather, they wilt result in increased
oil consumption when used above 32°F.
Check your engine oil level more frequent-
ly 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.
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.

TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm°
• Catch oil in a suitable container.
1. Remove oit fill cap/dipstick. Be careful
not to allow dirt to enter the engine
when changing oil,
2, Remove yellow cap from end of drain
valve and insta!l the drain tube onto

pin is in the locked position as shown.
6, Remove the drain tube and replace the
cap onto the end of the drain valve.
7. Refill engine with oil through oil fill dip-
stick tube, Pour slowly, Do not overfill.
For approximate capacity see "PROD-
UCT SPECIFICATIONS" section of this
manual°
8, 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 "FULE line on dipstick, Tighten cap
onto the tube securely when finished.
ENGINE OIL FILTER
Replace the engine oil filter every season or
every other oil change if the tractor is used
more than 100 hours in one year.
