Engine oil change

NOTE: Change the engine oil when the engine is warm. Refer to the engine owner’s manual for the correct replacement oil and filter change recommendations.

WARNING! To prevent burns, the engine should be shut off and allowed to cool slightly so the engine is still warm but the surrounding surfaces and oil are not.

1.Park on a level surface. Apply parking brake.

2.Clean the dirt and debris from the area around the oil fill cap.

3.Remove the cap/dipstick.

4.Locate the drain hose at the left rear of the engine. Place an adequately sized container under the end of the drain hose and remove the oil drain plug.

5.Allow the oil to fully drain from the engine.

6.Replace the drain hose plug and tighten securely.

7.Fill the engine with new oil to the bottom of the fill tube threads. Check the level with the dipstick.

8.Replace the oil fill cap securely when the oil level is FULL.

9.Refer to the Service Journal for oil checking and changing intervals.

Transaxle (Transmission) Fluid Change

This transaxle is designed with an external filter for ease of maintenance. To ensure constant fluid quality levels and longer life, an oil filter change interval of every 200 hours is recommended.

The following procedure is performed with the transaxles installed in the mower and the mower on level ground. Apply the pump release valve for each transaxle and set the parking brake.

1.Remove the filter guard screws and filter guard. Clean any loose debris from around the perimeter of the filter. See illustration.

2.Place an oil drain pan (12" or more diameter and 8 qt. capacity is optimal) beneath the oil filter. Remove the oil filter from the transaxle.

3.After the oil has drained, wipe the filter base surface and apply a film of new oil to the gasket of the replacement filter.
