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.

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.

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.

MAINTENANCE

CLEAN AIR SCREEN 

Air screen must be kept free of dirt and chaff to prevent 

engine dam age from overheating.  Clean with a wire brush 

or compressed air to re move dirt and stubborn dried gum 

fibers.

ENGINE OIL FILTER

Replace the engine oil filter every season or every other oil 

change if the tractor is used more than 100 hours in one 

year.  See engine man u al.

AIR FILTER 

Your engine will not run properly using a dirty air filter. 

Service air cleaner more often under dusty conditions. 

See Engine Manual.

TO CHANGE ENGINE OIL (See Fig. 19) 

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.  Slide oil drain extension from the docking position on 

the engine blower housing and extend outward from 

engine.

3.  To open, twist cap counter-clockwise
4.  After oil is drained completely, replace cap and twist 

clockwise until it stops.

5.  Re-attach oil drain extension to engine blower housing.
6.  Refill engine with oil through oil fill dipstick tube. Pour 

slowly. Do not overfill. For approximate capacity see 

“PRODUCT SPEC I FI CA TIONS” section of this man u al.

7.  Use gauge on oil fill cap/dipstick for checking level.  For 

accurate reading, tighten dipstick cap securely onto the 

tube before removing dipstick.  Keep oil at “FULL” line on 

dipstick. Tighten cap onto the tube securely when finished.
