TRANSAXLE COOLING
The transmissionfan and coolingfins
should be kept clean to assure proper
cooling.
Do not attemptto clean fan or transmis-
sion while engine is running or while the
transmission is hot. Toprevent 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.
• Inspect coolingfins for dirt, grass clip-
pings and other materials. Toprevent
damageto seals, do not use com-
pressed air or high pressure sprayerto
clean coolingfins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory
and fluid maintenance is not required for
the life of the transaxle. Should the trans-
axle ever leak or require servicing, contact
your nearest Sears or other qualified
service center.
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.
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 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.

Select the oil's SAE viscosity grade
according to your expected operating
temperature.

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 frequent-
ly to avoid possible engine damage from
running low on oil.

3. Unlock drain valve by pushing inward
slightly and turning counterclockwise.
4. To open, pull out on the drain valve.
5. 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.
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. For accurate reading,
insert dipstick into the tube and push
down firmly into place before removing.
Keep oil up to, but not over, the "FULF'
line on dipstick. Push dipstick down
firmly into the tube when finished.
