Engine Oil and Filter
Check the engine oil daily and after every 4 hours of
operation. The mower must be level when checking the oil.
Refer to the Engine Owner’s Manual and maintenance
schedule for oil recommendation and capacities. Hustler
®
Motor Oil is recommended.
Change the engine oil and filter after the first 5 hours of
operation and per the engine manufacturer’s
recommendations after that. Change the engine oil more
frequently if operating in extremely dirty conditions.
IMPORTANT: After the new oil filter has been installed,
clean up any oil which may have spilled onto the engine
plate, engine exhaust system, and muffler guard.
Draining the Engine Oil:
1. Locate the oil drain valve on the lower right side of the
engine. Figure 4-9 & Figure 4-10
2. Position a suitable oil drain container under the
machine below the oil drain valve.
3. 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.
4. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
5. Once the valve is closed, clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the engine plate, engine exhaust system, and
muffler guard before operating the machine.
