Changing your hydraulic oil and filter

fluid reservoirs and get an oil drain
pan. Lift the mower from the rear will
make access to the transaxles easier
and allow you to purge the air from
the transaxles.
2) Remove the three ¼” filter guard
screws and filter guard from the ZT-
3400 Transaxle. Clean any loose
debris from around the perimeter of
the filter.

drain as well. Remove the oil filter from
the transaxle.
4) After the oil has drained, wipe the filter
base surface off and apply a film of new
oil to the gasket of the new replacement
filter.
5) Install the new filter by hand, turn ¾ to
one full turn after the filter gasket
contacts the filter base surface.
6) Re-install the filter guard with three ¼”
screws. Torque screws to 65 in. lbs. (7.3
Nm) each.
