The blades may be removed as follows.
The blade can be tested by balancing it on a round
shaft screwdriver. Grind metal from the heavy side until
it balances evenly.

•
Remove the deck from beneath the tractor, (refer to
DECK REMOVAL) then gently flip the deck over to
expose its underside.
Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 19.
Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 19.
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.

BATTERY
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
WARNING: Shield eyes (e.g. goggles, face
shield) and protect skin and clothing when
handling battery acid or a battery containing
acid.
•
•
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.
Do not jump-start a damaged battery.
When storing the battery, disconnect the negative
terminal and store with full charge.
Sharpen Edge Evenly

3.
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.
CHARGING
IMPORTANT: When charging your tractor’s battery,
use only a charger designed for 12V lead-acid
batteries. Read your battery charger’s Owner’s Manual
prior to charging your tractor’s battery. Always follow its
instructions and heed its warnings.
IMPORTANT: If the cutting edge of the blade has
already 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.
If your tractor has not been put into use for an extended
period of time, charge the battery as follows:
It is important that each cutting blade edge be ground
equally to maintain proper blade balance.
Set your battery charger to deliver a maximum of 10
amperes. If your battery charger is automatic, charge
the battery until the charger indicates that charging is
complete.
A poorly balanced blade will cause excessive vibration
and may cause damage to the tractor and result in
personal injury.
If the charger is not automatic, charge for no fewer than
eight hours.
