Tractor
WARNING
Periodically inspect
the blade spindles for
cracks or damage,
especially if you strike
a foreign object.
Replace immediately if
damaged.
Cutting Blades
WARNING: Be sure to shut the
engine off, remove ignition
key, disconnect the spark plug
wire(s) and ground against the
engine to prevent unintended
starting before removing the cut-
ting 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 spindles for cracks or
damage, especially if you strike a
foreign object. Replace immedi-
ately if damaged.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor, (refer to
Cutting Deck Removal on page 21) then gently flip
the deck over to expose its underside.
2. Place a block of wood between the center deck hous-
ing baffle and the cutting blade to act as a stabilizer.
See Figure 20.
3. Use a 15/16” wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 20.
4. 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 to within 1 5/8” from the edge, or if any
metal separation is present, replace the blades with new
ones. See Figure 21.
• It is important that each cutting blade edge be ground
equally to maintain proper blade balance.
• 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 the blade
spindle hex flange nut to between 70 foot-pounds and 90
foot-pounds.

Fuses
• A fuse is 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.
• It can either be found under the hood mounted behind
the top of the dash panel on the support bar, or under
the seat mounted to the inside of the tractor frame
next to the battery tray.
Always use a fuse with the same
amperage capacity for replace-
ment.
