Replace the engine oil filter every season or every other 

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

one year.

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. 

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 transmission.
• 

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 

compressed air or high pressure sprayer to clean 

cool ing fins.

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.

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

vice air cleaner more often under dusty conditions. 

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.

Inspect and replace corroded muffler and spark arrester (if 

equipped) as it could create a fire hazard and/or damage.

Replace spark plugs at the beginning of each mowing 

season or after every 100 hours of operation, whichever 

occurs first.  Spark plug type and gap setting are shown in 

“PROD UCT SPECIFICATIONS” section of this manual.

To ensure proper cooling, make sure the grass screen, 

cooling fins, and other external surfaces of the engine are 

kept clean at all times.
Every 100 hours of operation (more often under extremely 

dusty, dirty conditions), remove the blower housing and 

other cooling shrouds. Clean the cooling fins and external 

surfaces as necessary. Ensure the cooling shrouds are 

reinstalled.
NOTE: Operating the engine with a blocked grass screen, 

dirty or plugged cooling fins, and/or cooling shrouds re moved 

will cause engine damage due to overheating.

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.    

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.
• 

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 

coun ter clock wise. 

•  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 capacity see 

“PRODUCT SPECIFICATIONS” section of this man u al.

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

Insert dipstick into the tube and rest the oil fill cap on 

the tube.  Do not thread the cap onto the tube when 

taking reading. Keep oil at “FULL” line on dipstick.  

Tighten cap onto the tube securely when finished.
