CHECKING TRANSMISSION/HYDRAULIC
SYSTEM OIL LEVEL
Check the hydro transmission/hydraulic system oil
level before each use. NOTE: Check the oil level
only while the engine is stopped and the tractor is
standing on a level surface.
The oil level sight glass is located in the rear of the
transmission housing, just to the right of the rear
PTO shaft. Refer to Figure 41.
The oil level is okay if oil can be seen through the
sight glass. If the level is below the sight glass, oil
must be added to the transmission as follows:
• Locate the oil fill plug on the upper right of the
rear of the transmission housing. See Figure 41.
Figure 41
• Clean the area around the oil fill plug to prevent
debris from entering the transmission housing.
• Turn the oil fill plug counterclockwise to unscrew
from the transmission housing.
• Insert a funnel (preferably with a flexible spout)
into the fill hole of the transmission housing.
• Add Cub Cadet Drive System Plus oil until the
oil level can be seen through the sight glass.
Do not overfill the transmission.
IMPORTANT: Always use Cub Cadet Drive
System Plus oil to ensure correct formulation.
Substitute oils could affect performance and
may cause damage to the transmission.
• Reinsert the oil fill plug into the transmission
housing and turn clockwise until tight.
CHANGING THE HYDRO TRANSMISSION AND
HYDRAULIC SYSTEM OIL FILTERS
The hydraulic system oil filter and hydro transmis-
sion filter should be changed after the first 25 hours
of operation. Thereafter the hydro transmission fil-
ter should be changed after every 100 hours of
operation, and the hydraulic system oil filter
changed after every 200 hours of operation along
with the transmission/hydraulic system oil.
25 Hour 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, both the hydro transmission and hydraulic
system filters should be changed after the first 25
hours of operation.
Hydro Pump Filter — Part No. BS-492392S
Hydraulic System Filter — Part No. 723-0405
NOTE: If a front end loader, or a loader and back-
hoe, is installed on the tractor after the first 25
hours of operation, it is recommended that the fil-
ters again be changed after the first 25 hours of
operation with these attachments installed.
Changing Hydro Transmission Oil Filter
The hydro transmission oil filter should be changed
after the first 25 of tractor operation, and after every
100 hours operation.
• Stop the tractor engine and lower the mower
deck or any other hydraulically lifted implement
to the ground.
• Slide the seat fully forward; then tilt seat forward.
• Through the access hole in the rear fender,
clean the area around the hydro transmission
oil filter to prevent debris from entering the
hydraulic system. Refer to Figure 42.
• Stuff shop rags underneath the hydro transmis-
sion filter to absorb any lost oil when the filter is
removed. Refer to Figure 42.
Figure 42
• Apply a light coating of clean transmission oil to
the gasket of the new hydro transmission filter.
