Remove the deck from beneath the tractor, (refer to
CtrttingDeckRemovalon page 19) then gently flip the
deck over to expose itsunderside.
Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 21.
Hex Flange Nut
Spindle Assembly
Figure 21
Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 21.
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 22.
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. See Figure 22.
Grind each cutting blade edge equally to maintain
proper blade balance.
_ WARNING: A poorlybalanced blade wilt
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 inthe operating position.
IMPORTANT: Use a torque wrench to tighten the blade
spindle hex flange nut to between 70 foot-pounds and
90 foot-pounds.

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.
1. One fuse is located under the hood mounted
behind the top of the dash panel on the support
bar.
2. 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 issealed and maintenance-free. Acid levels
cannot be checked. However, some care is required for
long battery life:
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, 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 to its terminal
first, followed by negative (black) wire.
