TRANSAXLE MAINTENANCE
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 transmission
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, grass clippings
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 near-
est Sears or other qualified service center.
V-BELTS
Check V-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

with API service classification SG-SL.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.

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 start-
ing the engine and after each eight (8)
hours of operation.
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.
