Maintenance Instructions
lubrication
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 the 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 clean oil to the rubber gasket on the replacement oil filter.
IMPORTANT: Use ONLY oil filters from the en gine manufacturer (Kohler
7.Install the new oil filter on the engine. Turn the filter clockwise until the rubber gasket contacts the sealing surface, then tighten an additional
1/2 turn.
8.Reinstall the drain plug. Make sure it is tight ened to 10 lb·ft (14 N·m).
9.Fill the crankcase with new, clean oil. Use only crankcase lubricants recommended by the en gine manufacturer. Refer to Specifications in this manual or the engine owner’s manual. Use the recommended oil viscosity for the expected ambient temperature. Oil with the correct vis cosity will aid starting in cold weather and assure proper lubrication in hot weather. Fill up to, but not above, the “F” mark on the dipstick. Crankcase capacity is 1.85 quarts (1.75 liters) plus 1/2 pint (0.24 liters) for the new oil filter.
IMPORTANT: Check the dipstick reading be fore adding the last 1/2 pint of oil and fill only to the “F” mark. DO NOT overfill the crankcase (oil above “F” mark) as this CAN result in en gine overheating, loss of power, and possible engine damage.
10.Start the engine and check for oil leaks around the oil filter. Stop the engine, recheck the oil level, and add oil if necessary. (When the en- gine is first operated with a new oil filter, the oil level drops slightly as the filter is filled with oil.)
Mower Deck Gearbox Lubrication
NOTE: These instructions apply to all mower decks with
On gear driven decks, the mower deck gearboxes (tee gearbox and blade drive gearboxes) are connected as a unitized assembly, and oil flows freelybetweenthem.Thegearboxesarepermanently lubricated (oil filled) and sealed requiring no scheduled lubrication. However, the gearbox oil seals should be checked every 25 hours for indication of an oil leak; particularly the lower seals on the blade drive gearboxes should be inspected, since they operate in a dirty environment. If an oil leak is noted, replace the oil seal and relubricate the gearbox assembly as follows:
1.Remove gearbox cover (footrest). Deck orien tation should be the normal operating position.
