1. Sharpen at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Figure 95). 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 96). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 96).
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 96). Torque the blade bolt to 85-110 ft-lb
(115-150 N-m).
