• Apply a light coating of clean transmission oil to
the gasket of the new hydro transmission filter.
• Remove the old hydrostatic filter by turning it
counterclockwise, and immediately replace with
the new filter. Turn the filter clockwise by hand
until the gasket contacts the filter base; then
tighten the filter an additional 1/2 to 3/4 turn.
• Clean any residual oil from the top of the
transmission.
Changing Hydraulic System Filter
The hydraulic system oil filter should be changed
after the first 25 of tractor operation, and after every
200 hours operation.
• Stop the tractor engine and lower the mower
deck or any other hydraulically lifted implement
to the ground. NOTE: To improve access to the
hydraulic system filter, the mower deck should
be removed from the tractor.
• The hydraulic system oil filter is remotely
mounted in the vertical position between the
tractor frame rails. See Figure 45.
• Clean the area around the oil filter to prevent
debris from entering the system.
• Position a suitable container below the hydrau-
lic system filter. See Figure 45.
NOTE (25 Hour Break-In Filter Change Only):
Some oil may drain from the transmission when
changing the hydraulic system oil filter. If collected
in a clean container and kept free of debris, this
oil may be reused in the transmission/hydraulic
system.

• Apply a light coating of clean transmission oil to
the gasket of the new hydraulic system oil filter.
NOTE: When performing the 25 hour break-in filter
change, install the new filter as quickly as possible
to minimize any loss of oil from the transmission.
• From beneath the tractor frame, remove the old
hydraulic system filter by turning it counter-
clockwise.
• When performing the 200 hour filter change,
clean the oil filter adapter.
• Install the new filter. Turn the filter clockwise,
by hand, until the gasket contacts the surface
of the filter adapter; then tighten the filter an
additional 1/2 to 3/4 turn.
• Clean the area around the transmission oil fill
plug to prevent debris from entering the
transmission (Refer to Figure 43) and remove
the plug.
