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.
Cutting Blades
WARNING:
Be sure to shut the engine off,
remove ignition key to prevent unintended
starting before removing the cutting blade(s)
for sharpening or replacement. Protect your
hands by using heavy gloves or a rag to grasp
the cutting blade.
WARNING:
Periodically inspect the blade
adapter and/or spindle for cracks or damage,
especially if you strike a foreign object.
Replace immediately if damaged
.
The blades may be removed as follows.
•
Remove the deck from beneath the tractor, (refer to
DECK REMOVAL) then carefully 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 .
•
Remove the hex flange nut that secures the blade
to the spindle assembly. See Figure 19.
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.
IMPORTANT:
If the cutting edge of the blade has already
been sharpened,or if any metal separation is present,
replace the blades with new ones.
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.
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 wrench to tighten blade
spindle hex flange nut to between 70 ft-lbs (95N-m) and
90 ft-lbs (122 N-m).

Battery
The battery is sealed and is maintenance-free. Acid
levels cannot be checked and fluid cannot be added.
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 to the POSITIVE (+) terminal
before connecting the NEGATIVE (Black) wire to the
NEGATIVE (-) terminal. 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.
