• Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 19.
To properly sharpen the cutting blades, remove equal
amounts of metal from both ends of the blades along
the cutting edges, parallel to the trailing edge, at a 25°
to 30° angle. See Figure 20.

been sharpened to within 5/8" of the wind wing radius,
or if any metal separation is present, replace the blades
with new ones. See Figure 20.
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.
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

Tires
WARNING:
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for the
front tires. Refer to the tire sidewall for exact tire
manufacturer's recommended or maximum psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.
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.
If removing the battery for any reason,
IMPORTANT:
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.
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:
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.
