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.
•Clean the area around the oil filler cap to prevent debris from entering the crankcase. Refer to Figure 46.
•Turn the oil filler cap counterclockwise to unscrew from the right valve cover.
•SLOWLY pour oil into the crankcase until the oil level reaches the “FULL” mark on the dipstick. Refer to Figure 47.
•Insert the oil fill cap into the valve cover and turn clockwise until fully tightened. Reinsert the dipstick into the dipstick tube and push firmly into the tube.
IMPORTANT: The oil fill cap and dipstick must always be installed securely in place when the engine is running. Severe engine damage could result from failure to do so.
CHANGING THE ENGINE OIL AND FILTER
WARNING: Because the engine is run prior to draining the oil, the engine may be hot. Use caution to avoid burning yourself on engine surfaces.
The engine oil and oil filter should be changed after the first eight hours of operation and every 100 hours thereafter. Refer to the LUBRICATION TABLE in the MAINTENANCE SECTION of this manual for the quantity of oil needed, and to deter- mine the proper type of oil to use for the conditions under which the engine will be operated.
Run the engine for a few minutes to allow the oil in the crankcase to warm up. Warm oil will flow more freely and carry away more engine impurities. Use care to avoid burns from hot oil. While the engine oil is warm, proceed as follows:
•Place the tractor on a level surface and engage the parking brake. Stop the tractor engine and remove the ignition key.
•Clean around the base of the oil filter, the oil filler cap, and the dipstick tube to prevent debris from entering the crankcase.
•Remove the dipstick and oil fill cap from the engine. Refer to Figure 46.
•Locate the engine drain valve on the rear of the engine (See Figure 48). Place a suitable container below the open end of the drain valve to collect the old oil.
