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 park
brake,
1, Remove the three filter guard screws and filter guard,
Clean any loose debris from around the perimeter of the
filter,
2, Place an oil drain pan (31 cm or more diameter and 8

surface,
5, Reinstall the filter guard, Torque screws to
65 in/Ibs, each,
6, Repeat steps on the opposite side,

Place used oil in appropriate containers and dispose of it
in accordance with laws in your area,
8, Remove the top port plug (see illustration) from the left

located on the vehicle frame,
10, Fill with 20W50 motor oil until oil just appears at the bottom
of each transaxles' top port (approximately 2 quarts per
