Lubrication
WARNING!
Before lubricating, repairing, or
inspecting, always disengage PTO, move shift lever
into neutral position, set parking brake, stop engine
and remove key to prevent unintended starting.
Engine
Lubricate the engine with motor oil as instructed in the Engine
Owner Manual packed with your unit.
Pivot Points & Linkage
Lubricate all the pivot points on the drive system, parking brake
and lift linkage at least once a season with light oil.
Rear Wheels
The rear wheels should be removed from the axles once a
season. Lubricate the axles and the rims well with an all-purpose
grease before re-installing them.
Front Axles
Each end of the tractor’s front pivot bar may be equipped with a
grease fitting. Lubricate with a grease gun after every 25 hours of
tractor operation.
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
could change the polarity and result in damage to your engine’s
alternating system.
Cleaning Battery
Clean the battery by removing it from the tractor and washing
with a baking soda and water solution. If necessary, scrape the
battery terminals with a wire brush to remove deposits. Coat
terminals and exposed wiring with grease or petroleum jelly to
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.
