MAINTENANCE
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 ensure proper cooling.
Do not attempt to clean fan or transmission while engine
is running or while the transmission is hot. To prevent pos-
sible damage to seals, do not use high pressure water or
steam to clean transaxle.
• Inspect cooling fan to ensure fan blades are intact and
clean.
Inspect cooling fins for dirt, 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 mainte-
nance is not required for the life of the transaxle. Should
the transaxle ever leak or require servicing, contact your
nearest authorized service center/department.
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.
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 operation 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 (See Figs. 17 & 18)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Ensure 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 yellow cap from end of drain valve and install
the drain tube onto the fitting.

• Unlock drain valve by pushing inward 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 to the
bottom fitting of the drain valve.
• Refill engine with oil through oil fill dipstick tube.
Pour slowly. Do not overfill. For approximate capac-
ity see Product Specifications section of this manual.
• Use gauge on oil fill cap/dipstick for checking level.
Ensure dipstick cap is tightened securely for accurate
reading. Keep oil at "FULL' line on dipstick. Tighten
cap onto the tube securely when finished.
