•Clean the area around the oil filler cap to prevent debris from entering the crankcase. See Figure 51.
OIL FILL CAP
•Remove the dipstick and oil fill cap from the engine. Refer to Figure 50 and Figure 51.
•Locate the engine drain plug on the bottom/ right side of the engine (See Figure 52). Place a suitable container below the drain plug to collect the old oil.

•Turn the oil filler cap counterclockwise to unscrew from the valve cover.
•SLOWLY pour oil into the crankcase until the oil level reaches the “FULL” mark on the dipstick. Refer to Figure 50.
•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. Clip the dipstick handle into the retaining clip.
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
The engine oil and oil filter should be changed after the first fifty hours of operation and every 150 hours thereafter. Refer to the LUBRICATION TABLE in the MAINTENANCE SECTION of this manual for the quantity of oil needed, and to determine the proper type of oil to use for the conditions under which the engine will be operated.
WARNING: Because the engine is oper- ated prior to draining the oil, the engine may be hot. Use caution to avoid burn- ing yourself on engine surfaces.
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.

•Refill the crankcase to the "FULL" mark on the dipstick with the appropriate type oil.
•Reinstall the oil fill cap and dipstick.
