Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening
blades.
1. Sharpen the cutting edge at both ends of the blade
(Figure 23). 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 24). 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 25). Repeat this procedure
until the blade is balanced.

Installing the Blades

center blades.
1. Install the blade onto the spindle shaft (Figure 25).
Important: The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the anti-scalp plate and blade bolt (Figure 25).
