Maintenance
Introduction
Contact a local dealer for parts and service assistance. For
the correct part or information for a particular Rear Engine
Riding Mower, always mention the model and serial number.
We recommend returning the Rear Engine Rider to an
authorized dealer annually for inspection and addition of any
new devices, which might upgrade the safety of the Rear
Engine Rider.
Change Engine Oil
1. Place bricks or wooden blocks under the front wheels to
lower the rear of the engine.
2. Loosen or remove the oil fill cap on the engine.
3. Place a 2 quart minimum capacity container under the
end of the oil drain (Figure 19).
4. Remove or open the oil drain plug (A or B, Figure 19),
depending upon the type of oil drain plug the engine is
equipped with.
5. After all the oil has drained, replace or close the drain
plug, and wipe up any oil that may have spilled.
Dispose of used oil properly.
6. Fill the engine crankcase with new oil. Refer to the
engine manual for oil specifications.
7. Change the oil filter on engines equipped with oil filters
at every oil change. Refer to the engine manual for serv-
ice instructions.
Service Engine Air Cleaner
The engine is equipped with a dual element air cleaner. Both
the foam pre-cleaner and cartridge require service. Refer to
the Engine Manual for recommended service procedures.
