Sharpening the Blades

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 (Fig. 466). Maintain the original angle.
The blade retains its balance if the same amount of
material is removed from both cutting edges.
A. Sharpen at original angle
2. Check the balance of the blade by putting it on a
6
blade balancer (Fig. 467). 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 (Fig. 468). Repeat this
procedure until the blade is balanced.

Important: The curved part of the blade must be
pointing upward toward the inside of the mower
to ensure proper cutting.

cone must be installed toward the bolt head (Fig.
