Transaxle Maintenance
This Zero Turn Mower has two Transaxles. The
Transaxles have external filters for ease of maintenance.
To ensure fluid quality and longer life, changing the oil
and filter after the initial 50 hours of Zero Turn Mower
usage then every 400 hours thereafter is recommended.
NOTE: Recommended oil is 20W50 motor oil.
The Zero Turn Mower must be parked on a level sur-
face, parking brake set and bypass lever on each
transaxle applied.
Allow the Zero Turn Mower to cool down before pro-
ceeding to perform maintenance.
Fluid and Filter Change Procedure

guard. Clean any loose debris from around the perimeter
of the filter.
2. Place an oil drain pan (12" or more diameter and 8 qt.

filter from the transaxle.

off and apply a film of new oil to the gasket of the new
replacement filter (Hydro-Gear part number 52114).
