Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil after every 100
hours of operation and replace the oil lter every
other oil change (every 200 hours of operation).
1. Park the mower on a level surface with the
en gine 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 the dipstick to keep any dirt or debris out
of the engine.
3. Remove the dipstick and the 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 lter, clean the area
around the lter to keep dirt and debris out of
the engine.
5. Remove the old oil lter and wipe off the lter
mounting surface on the engine.
6. Apply a thin coating of clean oil to the rubber
gasket on the replacement oil lter.
IMPORTANT: Use ONLY oil lters from the en-
gine manufacturer (Kohler 12-050-01). After-
market oil lters may not seal properly and/or
may not have the correct pressure relief valve
for proper lubrication.
7. Install the new oil lter on the engine. Turn the
lter clockwise until the rubber gasket contacts
the sealing surface, then tighten an additional
3/4 to 1 turn.
8. Reinstall the drain plug. Make sure it is tight-
ened to 10 lb·ft (14 N·m).
9. Fill the crankcase through the oil ller tube (dip-
stick opening) with new, clean oil. Use only
crankcase lubricants recommended by the en-
gine manufacturer. Refer to Specications 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 lter.
IMPORTANT: Check the dipstick reading be-
fore adding the last 1/2 pint of oil and ll only to
the “F” mark. DO NOT overll 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 lter. Stop the engine, recheck the oil
level, and add oil if necessary. (When the en-
gine is rst operated with a new oil lter, the oil
level drops slightly as the lter is lled with oil.)
Mower Deck Gearbox Lubrication
NOTE: These instructions apply to all mower decks
with gear-driven blades. Refer to DS52 or DS62
Mower Deck Lubrication in this section for the
DS52 or DS62 deck with belt-driven blades. Refer
to Mower Deck Spindle Lubrication in this section
for the DS42 Belt Drive deck with belt-driven blades.
On gear driven decks, the mower deck gearboxes
(tee gearbox and blade drive gearboxes) are con-
nected as a unitized as sembly, and oil ows freely
between them. The gear boxes are permanently lu-
bricated (oil lled) and sealed requiring no sched-
uled lubrication. Howev er, 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 en vironment. If an oil leak is
noted, replace the oil seal and relubricate the gear-
box assembly as follows:
1. Remove gearbox cover (footrest). Deck orien-
tation should be the normal operating position.
