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- sible damage to seals, do not use high pressure water or steam to clean transaxle.
eInspect cooling fan to be sure fan blades are intact and clean.
eInspect 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 coolingfins.
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.

NOTE: Although
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. 18 & 19)
Determine temperature range expected before oil change. All oil must meet API service classification
•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 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 capacity see "PRODUCT SPECIFICATIONS" section of this manual.
Use gauge on oil fill cap/dipstick for checking level. Be sure dipstick cap is tightened securely for accurate reading. Keep oil at "FULl" line on dipstick. Tighten cap onto the tube securely when finished.
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.
AIR FILTER
Your engine will not run properly using a dirty air filter. Ser- vice air cleaner more often under dusty conditions.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush
or compressed air to remove dirt and stubborn dried gum fibers.
ENGINE COOLING SYSTEM
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 removed will cause engine damage due to overheating.
SPARK PLUGS
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 "PRODUCT SPECIFICATIONS" section of this manual.
