Installing the Blades
1. Install the blade onto the spindle shaft (Figure 35).
,
Important:
The curved part of the blade must
be pointing upward toward the inside of the
mower to ensure proper cutting.
Install the blade stiffener, the curved washer (cupped
side toward the blade) and the blade bolt (Figure 35).
3. Torque the blade bolt to 35-65 ft-lb (47-88 N-m).
Leveling the Mower from
Side-to-Side
The mower blades must be level from side to side.
Check the side-to-side level any time you install the
mower or when you see an uneven cut on your lawn.

the blade control switch.

Measure between the outside cutting edges and
the flat surface (Figure 38). If both measurements
are not within 3/16 inch (5 mm), an adjustment is
required; continue with this procedure.
At the left side of the machine. Loosen, but do not
remove, the rear loc_ng nut on the hanger bracket
(Figure 39).
Loosen the side loc_ng nut on the hanger bracket
just enough to allow the centric plate to be adjusted
(Figure 39). Use a 3/8 inch drive extension on a
socket wrench to manipulate the centric plate. Use
the wrench to reposition the height of the mower
deck and adjust to the desired height.
Stop the deck at the adjusted position and tighten
the side loc_ng nut on the hanger bracket to hold
the new position (Figure 39).
Continue leveling the deck t937 chec_ng the
front-to-rear blade slope; refer to Adjusting the
Front-to-Rear Blade Slope.
