ENGINE MAINTENANCE
General Engine Maintenance
Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine Owner’s
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
manufacturer. Special attention should be paid to applicable
data which will not be duplicated here.
Engine Oil and Filter
Check engine oil daily and after every four (4) hours of
operation. Mower must be on a level surface when checking
oil. Refer to engine manual and maintenance schedule for oil
recommendation and capacities.
Change the engine oil and filter after the first five (5) hours
of operation and then per the engine manufacturer’s recom-
mendations after that. If mower is being operated in
extremely dirty conditions, then it is recommended oil be
changed more frequently.
IMPORTANT: After the new oil filter has been installed,
clean up any oil which may have spilled onto the engine
plate, muffler, and heat shield.
Draining the Engine Oil:
1. Locate the oil drain valve on the lower right side of the
engine. Figure 5-1 & Figure 5-2
2. Locate the oil drain hose that was supplied with the
machine. Be sure to clean and clear it of debris that
might block the flow of the engine oil. Figure 5-1 &
Figure 5-2
3. Attach one end of the hose onto the oil drain valve nip-
ple. Make sure the hose is pushed all the way onto the
valve. Figure 5-1 & Figure 5-2
4. Position the loose end of the hose forward and down
in front of the right side transmission so that it can
drain into a suitable oil drain container.
5. With the hose in position, use a 10 mm wrench or
socket and open the valve approximately 4 turns in the
counterclockwise direction. Allow 10 minutes for
engine oil to adequately drain.
6. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
7. Once the valve is closed, carefully remove the oil drain
hose and clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the exhaust system before operating the machine.
8. Clean the oil drain hose and store it appropriately.

Engine Air Filter
Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.
Fuel Evaporation System Filter
These mowers have a fuel evaporation system filter. This
filter must be checked and replaced every 100 hours or annu-
ally whichever comes first. Figure
5-3
If the engine has been running and is up to operating
temperature, allow the engine to cool before chang-
ing the oil. Engine and engine oil will be very hot, so
be very careful when changing oil and wear the
appropriate protective gear to avoid being burned or
exposed to engine oil.
