CHANGING TRANSMISSION/HYDRAULIC
SYSTEM OIL
Change the hydrostatic transmission/hydraulic
system oil and filters after every 200 hours of
operation. The dry capacity of the transmission/
hydraulic system is approximately 26 quarts.
Change the transmission/hydraulic system oil as
follows:
• Operate the tractor for a short period to warm
the oil to the normal operating temperature.
Place the tractor on a level surface, engage the
parking brake, and stop the tractor engine.
• Remove any belly mounted attachments.
• Clean the area around the transmission drain
plug and the oil fill plug/dipstick to prevent
debris from entering the transmission. Refer to
Figure 44 and Figure 45.
Figure 45
• Place a suitable container(s) beneath the front
of the transmission housing.
• Remove the oil fill plug/dipstick to help vent the
transmission, then remove the drain plug and
allow the transmission oil to drain into the
container(s). Reinstall the drain plug after
draining the oil. See Figure 45.
Dispose of used oil in an environmentally
safe manner. If necessary, contact your
area EPA office for proper disposal proce-
dures and recycling center locations.
• Clean around the base of the hydrostatic
transmission oil filter and remove the filter by
turning it counterclockwise. See Figure 45.
• Apply a light coating of clean transmission oil to
the gasket of the new filter. Install the filter by
turning it clockwise, by hand, until the gasket
contacts the filter base on the transmission
housing; then tighten the filter an additional 1/2
to 3/4 turn.
• Clean around the base of the hydraulic system
oil filter and remove the filter by turning it
counterclockwise. Refer to Figure 45.
• Apply a light coating of clean transmission oil to
the gasket of the new filter. Install the filter by
turning it clockwise, by hand, until the gasket
contacts the filter base on the transmission
housing; then tighten the filter an additional 1/2
to 3/4 turn.
• Loosely position a funnel in the oil fill hole so
that there is enough clearance around the fun-
nel to allow the transmission to vent while the
oil is poured into the transmission. Fill ONLY to
the full mark on the dipstick, never overfill the
transmission.
NOTE: Always use Cub Cadet hydraulic oil and
filters to ensure correct formulation and filtering
capacity. Substitute oils and/or filters could affect
performance and may cause damage to the
transmission.
• Reinsert the oil fill plug/dipstick into the
transmission housing and turn clockwise until
tight.
• Start the engine and allow it to run for a few
minutes. Shut the engine off, then check for
leaks and recheck the oil level in the
transmission housing.
CHANGING HYDROSTATIC TRANSMISSION
AND HYDRAULIC SYSTEM OIL FILTERS
NOTE: With the exception of the first oil filter
change after the 25 hour break-in period, the
hydrostatic transmission and hydraulic system oil
filters should be changed along with the hydrostatic
transmission/hydraulic system oil after every 200
hours of operation.
Initial Break-In Period Filter Change
During the initial hours of tractor operation,
contaminants caused by the normal break-in of
internal transmission and hydraulic system
components will collect in the oil filters. Because of
this, the filters should be changed after the first 25
hours of operation.
