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
recommendations, bolt torques, etc. The engine warranty is
backed by the engine manufacturer. Special attention should
be paid to applicable data which will not be duplicated here.

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 5-1 & Figure 5-2

2.

Position a suitable oil drain container under the oil
drain valve to catch the oil as it drains from the engine.

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.

Remove the oil drain container from under the mower. 

IMPORTANT: 

All oil drips or spills 

must 

be cleaned off

of the engine plate, engine exhaust system, and
muffler guard before operating the machine.    

Allow the engine to cool before changing the
engine oil. If the engine has been running, use
caution when changing the engine oil as it will be
very hot. You should wear the appropriate
protective gear to avoid being burned or exposed
to engine oil.
