Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 191). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

M-1854
2. Check the balance of the blade by putting it on a
blade balancer (Figure 192). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the end of the sail area only
(Figure
190
). Repeat this procedure until the blade is
balanced.

Installing the Blades
1. Install the blade onto the spindle shaft
(Figure
190
).
The sail part of the blade must be
pointing upward, toward the inside of the mower to
ensure proper cutting
(Figure 190).
2. Install the washer, lock washer and blade bolt
(Figure 190). Torque the blade bolt to 85 - 110 ft-lb
(115 - 140 N-m).
