TRANSAXLE COOLING
The fan and cooling fins of transmission 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.
•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 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.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
FIG. 20
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. 20 and 21) Determine temperature range expected before oil change. All oil must meet API service classification SF, SG or SH.
•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 drain plug.
•After oil has drained completely, replace oil drain plug and tighten securely.
•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. 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.

CLEAN AIR SCREEN (See Fig. 21)
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.
CLEAN AIR INTAKE/COOLING AREAS
To insure 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. Make sure 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.
AIR FILTER (See Fig. 22)
Your engine will not run properly using a dirty air filter. Clean the foam
Service air cleaner more often under dusty conditions.
•Loosen knob and remove cover.
