V-BELTS
Check V-belts for deterioration and wear
after 100 hours of operation and replace if
necessary. The belts are not adjustable.
Replace belts if they begin to slip from
wear.
TRANSAXLE
COOLING
The transmission
fan and cooling fins
should be kept clean to assure proper
cooling.
Do not attempt to clean fan or transmis-
sion while engine is running or while the
transmission is hot.
• Inspect cooling fan to be sure fan
blades are intact and clean.

The transaxle
was sealed at the factory
and fluid maintenance
is not required for
the life of the transaxle. Should the
transaxle ever leak or require servicing,
contact your nearest authorized service
center.
ENGINE
LUBRICATION
Only use high quality detergent oil rated
with API service classification SF, SG or
SH. Select the oil's SAE viscosity grade
according to your expected operating tem-
perature.
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°1=. Check your engine oil
level more frequently
toavoid
possible
engine damage from running low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the
tractor is not used for 25 hours in one
year.
Check the crankcase
oil level before start-
ing the engine and after each eight (8)
hours of operation. Tighten oil fill cap/dip-
stick 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
SF, SG or SH.
• 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.
• After oil has drained
completely, replace
oil drain plug and tighten securely.
• Refill engine with oil through
oil fill dip-
stick tube.
Pour slowly.
Do not overfill.
For approximate
capacity
see "PROD-
UCT SPECIFICATIONS"
on page 3 of
this manual.
• Use gauge on oil fill cap/dipstick
for
checking
level.
Be sure dipstick
cap is
tightened
securely
for accurate
reading.
Keep oil at "FULL"
line on dipstick.
