V-BELTS

Check V-belts for deterioration and wear after 100 hours 

of operation and replace if necessary. The belts are not 

ad just able. Re place 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 transmission while engine 

is running or while the transmission is hot. To prevent pos-

 si ble 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 cooling fins for dirt, grass clippings and other 

materials. To prevent damage to seals, do not use com-

pressed air or high pressure sprayer to clean cooling fins.

TRANSAXLE PUMP FLUID 

The transaxle was sealed at the factory and fluid main te-

 nance is not required for the life of the transaxle.  Should 

the transaxle ever leak or require servicing, contact your 

near est au tho rized ser vice center/department.

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.

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.    

TO CHANGE ENGINE OIL (See Fig. 18 & 19) 

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.

• 

Slide oil drain extension under oil drain hole (drain hole 

may be flush with or protrude from engine block side wall).

• 

Make sure back face of oil drain extension is flush with 

engine side wall.

•  Make sure bottom lip of oil drain extension is lined up 

with bottom of oil drain hole.

• 

Position a container to catch oil directly under front end 

of oil drain extension.

• 

Slide a 1/2” (12 point) socket mounted on an extension 

onto oil drain plug.

• 

Loosen plug while holding the oil drain extension firmly 

in place.

•  Drain oil into container.
• 

After oil has drained completely, reinstall oil drain plug.  

(Do not tighten more than 13 Ft. Lbs./17 Nm)

•  Refill engine with oil through oil fill dipstick tube.  Pour 

slowly.  Do not overfill.  For approximate capacity see 

“PRODUCT SPECIFICATIONS” section of this man u al.

•  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.

one year.
