Maintenance

3.Remove the oil drain plug from the right hand side of the engine. Allow oil to drain, replace drain plug.

4.Replace the oil filter per the engine owner’s manual. Clean around oil filter and unscrew filter to remove. Before the new filter is installed, apply a thin coating of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter, then tighten filter an additional 2/3 to 3/4 turn.

5.Clean around oil fill cap and remove cap. Fill to specified capacity and replace cap.

6.Use oil recommended in engine owner’s manual. Do Not overfill. Start the engine and check for leaks. Stop engine and recheck oil level.

Check Tire Pressures

Service Interval: Every 40 hours

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Check tire pressure in drive tires.

3.Inflate drive tires to 12–16 psi (83–110 kPa).

4.Inflate tires to pressures stated above. Measure the circumference of each drive tire. Adjust tire pressures within the above range to try to make tire circumferences match as closely as possible.

5.Semi-pneumatic caster tires Do Not need to be inflated.

Note: A more uniform cutting height may be obtained with higher tire pressure on rough terrain. A lower tire pressure provides more flotation.

Check Condition Of Belts

Service Interval: Every 40 hours

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Remove the mower deck belt shield to check mower blade drive belt condition.

3.Look under engine deck to check the transmission drive belt condition.

4.Inspect wheel drive belt conditions.

5.Check all idler arms to be sure they pivot freely. Disassemble, clean and grease pivot bushings if necessary.
