SECTION 4: MAINTENANCE
ENGINE MAINTENANCE
Engine maintenance procedures and schedules can
be found in the engine manual. Follow those instruc-
tions 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 21.
• Push the oil drain hose (packed with this man-
ual) 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 (62 oz.- ZT42; 80 oz.- ZT50).
Figure 21
• Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 21.
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 White Outdoor dealer.
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.
BATTERY REMOVAL
WARNING: Battery posts, terminals and
related accessories contain lead and
lead compounds. Wash hands after
handling.
The battery is located on the right/rear of the tractor
beneath the seat box frame.
To remove the battery:
• Push downward on the top rear of the battery
holddown rod and pull the bottom rearward to
release it from the tab in the frame. Rotate the
holddown rod upward and maneuver out of the
hole in the seat box.
• Remove the hex cap screw and sems nut secur-
ing the black negative battery lead to the negative
battery post (marked NEG). Move the cable away
from the negative battery post.
• Remove the hex cap screw and sems nut secur-
ing the red positive battery lead to the positive
battery post (marked POS).
• Carefully lift the battery out of the tractor.
Install the battery by repeating the above steps in the
reverse order.
WARNING: Always connect the positive
lead to the battery before connecting the
negative lead. This will prevent sparking
or possible injury from an electrical short
caused by contacting the tractor body
with tools being used to connect the
cables.
