Battery
The battery is sealed and is maintenance-free. Acid levels cannot
be checked.
• Always keep the battery cables and terminals clean and
free of corrosive build-up.
• After cleaning the battery and terminals, apply a light coat
of petroleum jelly or grease to both terminals.
• Always keep the rubber boot positioned over the positive
terminal to prevent shorting.
IMPORTANT:
If removing the battery for any reason,
disconnect the NEGATIVE (Black) wire from it's terminal first,
followed by the POSITIVE (Red) wire. When re-installing the
battery, always connect the POSITIVE (Red) wire its terminal
first, followed by the NEGATIVE (Black) wire. Be certain that the
wires are connected to the correct terminals; reversing them

prevent corrosion.
Battery Failures
Some common causes for battery failure are:
• Incorrect initial activation
• Overcharging
• Freezing
• Undercharging
• Corroded connections
These failures are NOT covered by your tractor's warranty.
Cleaning the Engine And Deck
Any fuel or oil spilled on the machine should be wiped off
promptly. Do NOT allow debris to accumulate around the cooling
fins of the engine or on any other part of the machine.
IMPORTANT:
The use of a pressure washer to clean your
tractor is NOT recommended. It may cause damage to electrical
components, spindles, pulleys, bearings or the engine.
A hex plug can be found on your tractor's deck surface. See Fig. 6-3.
This plug can be replaced with a water port to be used as part of
a separately-available deck wash system.
The Deck Wash System™ is used to rinse grass clippings from the
deck's underside and prevent the buildup of corrosive chemicals.
NOTE: Refer to the Attachments & Accessories section of this
manual for information regarding this and other separately-
available attachments & accessories for your tractor.
