It is important that each cutting blade edge be ground
equally to maintain proper blade balance.
A poorly balanced blade will cause excessive vibration
and may cause damage to the tractor and result in
personal injury.
The blade can be tested by balancing it on a round shaft
screwdriver. Grind metal from the heavy side until it
balances evenly.
IMPORTANT:
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 wrenchto tighten blade
spindle hex flange nut to between 70 ft-lbs and 90 ft-lbs

•
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 cause damage to your engine’s alternating
system.
IMPORTANT:
1.
Battery wires must be connected to the correct
terminals. Reversing them could change the polarity
and damage engine’s alternating system.
2.
Do not jump-start a damaged battery.
3.
When storing the battery, disconnect the negative
terminal and store with full charge.
Charging
If the unit has not been put into use for an extended
period of time, charge the battery with an automotive-
type 12-volt charger for a minimum of one hour at six
amps.
WARNING:
Batteries give off an explosive
gas while charging. Charge 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
WARNING:
When removing or installing the
battery, follow these instructions to prevent the
screwdriver from shorting against the frame.
IMPORTANT:
Never jump your tractor’s dead battery
with the battery of a running vehicle.
•
Connect end of one jumper cable to the positive
terminal of the good battery, then the other end to
the positive terminal of the dead battery.
•
Connect the other jumper cable to the negative
terminal of the good battery, then to the frame of the
unit with the dead battery.
WARNING:
Failure to use this procedure
could cause sparking, and the gas in either
battery could explode.
WARNING:
Do not use the tractor battery to
start other vehicles.
