ENGINE MAINTENANCE
WARNING: Use care when servicing any component in the engine area. If the engine has recently been operated, components will be hot and could cause burns. Allow the engine to cool before servicing.
WARNING: Before servicing the engine, place the tractor on a level surface, stop the engine, engage the parking brake, and remove the key from the ignition switch.

Check the radiator for any accumulation of debris lodged between cooling fins. Blow the debris out using compressed air directed from the fan shroud side of the radiator.
Reinsert the screen, making sure that it is in the slots of the radiator frame.
CHECKING ENGINE OIL LEVEL
Before each use, the oil level in the engine crankcase should be checked to see that it is filled to the correct level. During the "break in" period for the engine, closely monitor the engine oil level. The oil level should be checked hourly during the first 5 hours of operation.
•Check the oil level only while the engine is stopped and the tractor is level. Clean the area around the oil level dipstick to prevent debris from entering the crankcase. See Figure 50.
•If recently operated, allow the engine to cool and the oil to drain back into the oil pan.
•To check the oil level, release the dipstick handle from the retaining clip, then withdraw the dipstick and wipe it clean. Reinsert the dipstick all the way into the tube before withdrawing it for a true reading.

•Always keep the oil level between the full and the add marks on the dipstick. See Figure 50.
•Reinsert the dipstick into the dipstick tube and push firmly into the tube. Clip the dipstick handle into the retaining clip.
ADDING ENGINE OIL
WARNING: Never overfill the engine crankcase. The engine may overheat and/or damage may result if the crankcase is below the “ADD” mark or over the “FULL” mark on the dipstick. For best results, fill to the “FULL” mark on the dipstick as opposed to adding a given quantity of oil. Always check the level on the dipstick before adding more oil.
Refer to the LUBRICATION TABLE in the MAINTE- NANCE SECTION of this manual to determine the proper type of oil to add to the crankcase for the conditions under which the engine will be operated.
•Place the tractor on a level surface and engage the parking brake. Stop the tractor engine and remove the ignition key.
