page 29.
2. Carefully tip the mower over.

Sharpening the Blade
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 30). Maintain the original angle. The blade
retains its balance if you remove the same amount of
material from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 31). 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 of the back
side of the blade. Repeat this step until the blade is
balanced.
