Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil after every 50 hours of operation and the oil filter after every 100 hours of operation as follows:
1.Park the mower on a level surface with the engine stopped. The engine oil should be warm before draining. If not warm from opera- tion, start the engine and run a few minutes to warm the oil.
2.Before removing the dipstick, clean the area around it to keep any dirt or debris out of the engine.
3.Remove the dipstick and oil drain plug, and drain oil into a suitable container. Be sure to allow ample time for complete drainage.
4.Before removing the oil filter, clean the area around the filter to keep dirt and debris out of the engine.
5.Remove the old oil filter and wipe off the filter mounting surface on the engine.

6.Apply a thin coating of new oil to the rubber gas- ket on the replacement oil filter.
IMPORTANT: Use ONLY oil filters from the engine manufacturer. Aftermarket oil filters may not seal properly and/or may not have the cor- rect pressure relief valve for proper lubrication.
7.Install the new oil filter on the engine. Turn the oil filter clockwise until the rubber gasket con- tacts the sealing surface, then tighten the filter an additional 3/4 turn.
8.Reinstall the drain plug. Make sure it is tight- ened to 16.5
9.Fill the crankcase (through the dipstick opening) with oil using only crankcase lubricants supplied by the engine manufacturer. Refer to Specifica- tions in this manual or the engine owner’s manual. Use the recommended oil viscosity for the expected ambient temperature. Oil with the correct viscosity will aid starting in cold weather and assure proper lubrication in hot weather. Fill to FULL (H) mark on the dipstick; crankcase capacity is 2.7 pints (1.3 liters).
IMPORTANT: Check the dipstick reading be- fore pouring in the last 1/2 pint of oil and fill only to the FULL (H) mark. The oil level should never be over the FULL (H) mark on the dipstick; overfilling can result in engine overheating and loss of power.
10.Start the engine and check for oil leaks around the oil filter. Stop the engine, recheck the oil lev- el, and add oil if necessary. (When the engine is first operated with a new oil filter, the oil level will drop slightly as the filter is filled with oil.)
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after every 25 hours of operation. Lubricate more often when operating in dusty or dirty conditions. Use SAE general purpose lithium or molybdenum base grease for grease fittings and light machine oil (SAE
10)to lubricate oil points. Lubricate the locations shown in the Chassis and Deck Lubrication Points illustration.
NOTE: PTO universal joints (on the deck and trac- tor) require routine lubrication after every 8 hours of running time.
NOTE: The pillowblock bearings on the PTO drive shaft are a sealed,
