3. Remove the oil fill plug/dipstick from the oil fill port
and SLOWLY pour oil into the oil fill port. Fill the
transmission case until the oil level reaches the
"FULL" mark on the dipstick (Refer to Figure 21).
4. Reinstall the oil fill plug/dipstick securely into the
oil fill port.
IMPORTANT: The oil fill plug/dipstick must be
installed securely into the fill port at all times when
the engine is operating.
HYDROSTATIC DRIVE OIL FILTER
WARNING: Never overfill the transmis-
sion case. Damage or leakage may result
if the oil level in the transmission case is
below the "ADD" mark or over the
"FULL" mark of the dipstick. For best
results, fill to the "FULL" mark on the
dipstick as opposed to adding a given
quantity of oil. Always check the level on
the dipstick before adding more oil.
Refer to the MAINTENANCE CHART for information
regarding the frequency of the hydrostatic transmis-
sion oil filter replacement. The filter, part number 923-
3014, can be obtained from your Cub Cadet dealer.
Refer to the LUBRICATION TABLE for information
regarding the oil capacity and the proper type of oil to
pour into the transmission case.
1. Place the tractor on a level surface and engage the
brake pedal lock. Stop the tractor engine and
remove the ignition key.
2. Clean the area around the transmission drain plug
to prevent debris from entering the transmission
case. Remove the drain plug and allow the
transmission oil to drain into a clean container
having a capacity of more than 6 quarts. Reinstall
the drain plug (See Figure 22).

IMPORTANT: If the transmission oil is to be re-used,
cover the container holding the drained oil to prevent
contamination. Contaminated transmission oil can
damage the hydro transmission.
3. Clean around the base of the transmission oil filter
and remove the filter by turning it counterclockwise
(Refer to Figure 22).
4. 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 turn.
5. Clean the area around the transmission oil fill plug/
dipstick to prevent debris from entering the
transmission case.
6. Remove the oil fill plug/dipstick from the oil fill port
and SLOWLY pour oil into the oil fill port. Fill the
transmission case until the oil level reaches the
"FULL" mark on the dipstick (Refer to Figure 21).
7. Reinstall the oil fill plug/dipstick securely into the
oil fill port.
8. Start the engine and allow it to run for a few
minutes. Shut the engine off, then check for leaks
and re-check the oil level in the transmission case.
WARNING: The oil fill plug/dipstick must
be installed securely into the fill port at
all times when the engine is operating.
AIR CLEANER
Check the air cleaner daily or before starting the
engine. Check for loose or damaged components and
check the condition of the filter element. Remove any
buildup of dirt and debris in the air cleaner housing.
WARNING: Operating the engine with
loose or damaged air cleaner compo-
nents will allow unfiltered air into the
carburetor; causing extensive wear and
eventual failure of the engine.
Servicing the Precleaner
Wash and re-oil the foam precleaner at 1 month
intervals or after every 25 hours of operation (more
often under extremely dusty or dirty conditions),
whichever occurs first.
1. Unfasten the air cleaner cover retaining knob and
remove the air cleaner cover (Refer to Figure 23).
2. Remove the foam precleaner by sliding it up off the
paper element (Refer to Figure 23).
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until all
traces of the detergent are eliminated. Squeeze
out (do not wring) excess water in a dry cloth.
Allow the precleaner to air dry.
