TRANSAXLE COOLING
The transmission fan and cooling fins should
be kept clean to assure proper cooling.
Do not attempt to clean fan or transmission
while engine is running or while the trans-
mission is hot. To prevent possible damage
to seals, do not use high pressure water or
steam to clean transaxle.
• Inspect cooling fan to be sure fan blades
are intact and clean.
• Inspectcoolingfinsfordirt, grassclippings
and other materials. To prevent damage to
seals, do not use compressed air or high
pressure sprayer to clean cooling fins.
TRANSAXLE
PUMP FLUID
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
Sears or other qualified service center.
V-BELTS
Check \!-belts for deterioration and wear after
100 hours of operation and replace if neces-
sary. The belts are not adjustable. Replace
belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with
API service classification SG-SL. Select the
oil's SAE viscosity grade according to your
expected operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

Check the crankcase oil level before starting
the engine and after each eight (8) hours of
operation. Tighten oil fill cap/dipstick se-
curely 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 oil 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 install the drain tube onto
the fitting.

NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption
when used above 32°R 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 opera-
tion or at least once a year if the tractor is
not used for 50 hours in one year. 20
Unlock drain valve by pushing inward
slightly and turning counterclockwise.
To open, pull out on the drain valve.
After oil has drained completely, close
and lock the drain valve by pushing
inward and turning clockwise until the
pin is in the locked position as shown.
Remove the drain tube and replace the
cap onto the end of the drain valve.
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.
Use gauge on oil fill cap/dipstick for
checking level. For accurate reading,
insert dipstick into the tube and push
down firmly into place before removing.
Keep oil up to, but not over, the "FULL'
line on dipstick. Push dipstick down
firmly into the tube when finished.
