original angle. The blade retains its balance if
the same amount of material is removed from
both cutting edges.

1. Sharpen at original angle
2. Check the balance of the blade by putting it on
a blade balancer (Figure 40). If the blade stays
in a horizontal position, the blade is balanced
and can be used. If the blade is not balanced,
repeat the sharpening procedure on the heavier
side until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft
(Figure 38).
Important: The curved part of the blade
must be pointing upward toward the inside
of the mower to ensure proper cutting.
2. Install the curved washer (cupped side toward
the blade) and blade bolt (Figure 38). 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.
1. Position the mower on a flat surface.
Disengage the blade control switch, set the
parking brake, stop the engine, and remove the
key. Disconnect the spark plug wire(s) from
the spark plug(s).
2. Balancer
2. Check the air pressure of all four tires. If
needed, adjust to the recommended inflation;
refer to Tire Press.
3. Set the height-of-cut at 3 inch (76 mm).
4. Carefully rotate the blade(s) from side to side
(Figure 41). Measure between the outside
cutting edges and the flat surface (Figure 41).
If both measurements are not within 3/16 inch
(4.75 mm), an adjustment is required; refer to
steps 5 and 6.

5. Remove the hairpin cotter and washer from
the leveling bracket (Figure 42). To level the
blade(s), reposition the leveling bracket(s) in
a different hole and install the washer and
hairpin cotter. (Figure 42). A front hole lowers
the blade height and a rear hole raises its
height. Adjust both sides as required.
