Grind each cutting blade edge equally to maintain
proper blade balance.

WARNING"
A poorly balanced blade will
cause excessive vibration, may damage the
tractor and cause personal injury.
Test the blade by balancing it on a round shaft
screwdriver. Grind metal from the heavy side until it
balances evenly.
When replacing the blade, be sure to install the
blade with the side of the blade marked "Bottom"
(or with a part number stamped in it) facing the
ground when the mower is in the operating position.
IMPORTANT:Use a torque wrench to tighten the blade
spindle hex flange nut to between 70 foot-pounds and
90 foot-pounds.

WARNING"
Before servicing, repairing, or
inspecting, always disengage PTO, move shift
lever into neutral position, set parking brake,
stop engine and remove key to prevent
unintended starting.
Fuses
Two fuses are installed in your tractor's wiring harness
to protect the tractor's electrical system from damage
caused by excessive amperage.
•
If the electrical system does not function, or your
tractor's engine will not crank, first check to be
certain that the fuse has not blown. One fuse is
located under the hood mounted behind the top of
the dash panel on the support bar. The other can
be found under the seat mounted to the inside of
the tractor frame next to the battery tray. Pull the
fuse out and inspect it to determine if it is good or
blown. Replace if necessary.
IMPORTANT: Always use a fuse with the same
amperage capacity for replacement.
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.
IMPORTANT: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 its 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 polarity
and damage the engine's alternating system.
Charging
•
If the tractor has not been used for an extended
period of time, use a voltmeter or load tester to
measure the charge. The voltmeter should read
12.6 V or higher for adequate charge. Otherwise,
charge the battery with an automotive-type
12-volt
charger for a minimum of one hour at six amps.
Follow the chart below to charge:

WARNING:
Batteries give off an explosive
gas while charging. Charge the battery in a well
ventilated area and keep away from an open
flame or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
Jump-Starting
IMPORTANT:Do not jump-start a damaged battery.
Before connecting the jumper cables, make sure that
the two equipment are not in contact and their ignitions
are turned off. Follow the sequence described below
very closely.
1.
Connect the positive (+) lead of the jumper cable to
the positive (+) post of the discharged battery.
2.
Connect the other end of the positive (+) jumper
cable to the positive (+) post of the good battery.
3.
Connect one end of the negative (-) jumper cable to
the negative (-) post of the good battery.
4.
Connect the other end of the negative (-) cable to
the engine block of the stalled tractor, away from
the battery, and stand back.
