SECTION 4: MAINTENANCE
ENGINE MAINTENANCE
Engine maintenance procedures and schedules can
be found in the copy of the engine manual found at
the end of this manual. Follow those schedules for
performingengine maintenance.
Using the Engine Oil Drain Valve
• Locate the oildrain vaXveon the rightside of the
engine.
• Pop open the protective cap on the end of the oil
drain valve to expose the oil drain port. See
Figure 22.
• Push the oil drain hose (packed with this manual)
onto the oil drain port. Route the opposite end of
the hose into an appropriate oil collection
container with a capacity great enough to collect
the used oil as follows:
RZT 50 = 1.8 qts.;1.7liter
RZT 54 = 1.9 qts.;1.8liter

Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 22.
After draining the oil, remove the drain hose,
push the drain valve in and rotate clockwise to
lock in the dosed position. Push the protective
cap back onto the drain valve.
HYDROSTATIC TRANSMISSION MAINTENANCE
The zero turn tractor is equipped with dual integrated
hydrostatic pumps, motors, and transaxles that are
sealed and do not require regular maintenance.
All service work on the hydrostatic transmissions
should be performed by your Cub Cadet dealer.
Model RZT 54 ONLY
The model RZT54 is equippedwith a transmissionoil
expansion reservoir. Under normal operating condi-
tions,the oil level in the expansion reservoir does not
need to be checked and no additional oil is needed.
if checking the reservoir oil level, proceed as follows:
IMPORTANT: Check the oil level ONLY before
starting the tractor when the transmission oil is
fully cooled,
• Pivotthe operator'sseat forward
• Clean the reservoircap and the area aroundthe
cap to prevent debris from contaminating the
transmissionoil. See Figure23.

• Turn the reservoir cap counterclockwise to re-
move, then check the oil level in the reservoir. Oil
should be visible at the bottom of the cup, but the
oil level must NOT be above 1/4" from the bot-
tom of the cup. DO NOT FILL THE RESERVOIR.
= If necessary to add oil because of some type of
leakage, use a quality 20W50 motor oil and add
only enough oil to bring the level within 1/4" of the
bottom of the reservoir. Reinstall the cap and fully
tighten.
GENERAL BATFERY INFORMATION
i_ WARNING:
• Should battery acid accidentally splatter into the
eyes or onto the skin, rinse the affected area
immediately with clean cold water. If there is any
further discomfort, seek prompt medical attention.
• If acid spills on clothing, first dilute it with clean
water, then neutralize with a solution of ammonia/
water or baking soda/water.
• NEVER connect (or disconnect) battery charger
clips to the battery while the charger is turned on,
as it can cause sparks.
