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.
Remove the three ¼" filter guard screws and filter
1.
guard. Clean any loose debris from around the
perimeter of the filter. See illustration.
Place an oil drain pan (12" or more diameter and
2.
8 qt. capacity is optimal) beneath the oil filter.
Remove the oil filter from the transaxle.
After the oil has drained, wipe the filter base
3.
surface and apply a film of new oil to the gasket of
the replacement filter.
Install the new filter by hand, turning it three-

quarters to one full turn after the filter gasket
contacts the filter base surface.
Reinstall the filter guard. Torque screws to
