Remove the hairpin ciips which secure the rear
deck hangers to the deck stabilizer bracket. See
Figure 27. Retain the hairpin ciips.
* Carefully lower the rear portion of the deck to the
ground.
NOTE: For normal service and maintenance, the
deck stabilizer bracket doesn’t need to be removed
from the tractor. If removing the cutting deck in order to
mount a Snow Thrower attachment, however, the
stabilizer bracket must be removed. To do so, simply
remove the hairpin dip which secures the stabilizer rod
to the stabilizer bracket See Figure 27.
* Place the deck engagement/lifl lever in the
BLADES STOP position to raise the lift links up,
and out of the way.

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
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
Cutttng Deck Removal on page 22) 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 28.
* Use a 15/16“ wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 28.
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 29.
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 29.
