Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 81). Maintain the 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 82). 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 80). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 83).
Important:
The curved part of the blade must
be pointing upward toward the inside of the
mower to ensure proper cutting.
2. Install the spring disk and blade bolt. The spring
disk cone must be installed toward the bolt head
(Figure 83). Torque the blade bolt to 85-110 ft-lb
(115-150 N-m).
