SECTION 4: MAINTENANCE
ENGINE MAINTENANCE
Engine maintenance procedures and schedules can
be found in the engine manual found at the back of
this manual. Follow these schedules for performing
engine maintenance.
Using the Engine Oil Drain Valve
• Locate the oil drain valve on the left side of the
engine.
• Pop open the protective cap on the end of the oil
drain valve to expose the oil drain port. See
Figure 20.
• 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 (64 oz.; 1.9 liters).

• Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 20.
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.
Under normal operating conditions, the oil level in the
expansion reservoirs 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.
• Pivot the operator's seat forward
• Clean the reservoir caps and the area around the
caps to prevent debris from contaminating the
transmission oil. Refer to Figure 21.
• Turn reservoir cap counterclockwise to remove
and 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 bottom of
the cup. DO NOT FILL THE RESERVOIR.
• If needed, 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 BATTERY INFORMATION
_ WARNING:
• Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
• 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.
• Keep all sources of ignition (cigarettes, matches,
lighters) away from the battery. The hydrogen
gas generated during charging can be
combustible.
As a further precaution, only charge the battery in
a well ventilated area.
Always shield eyes and protect skin and clothing
when working near batteries.
WARNING: Batteries contain sulfuric
acid and may emit explosive gases. Use
extreme caution when handling batter-
ies. Keep batteries out of the reach of
children.
