Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 95).
Note: Maintain the original angle. The blade remains
balanced 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 96).
Note: 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 97). Repeat this procedure until the blade
is balanced.

Installing the Blades

Important: The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and the blade bolt.
Note: Install the spring disk cone toward the bolt
head (Figure 97). Torque the blade bolt to 115 to
150 N-m (85 to 110 ft-lb).
