Removing the Blades

1. Remove the mower; refer to Removing the Mower on

page 31.

2. Carefully tip the mower over.

3. Remove the bolt, curved washer, and blade (Fig. 34). A

block of wood may be wedged between the blade and

the mower to lock the blade when you are removing the

bolt.

Sharpening the Blades

1. Use a file to sharpen the cutting edge at both ends of the

blade (Fig. 35). Maintain the original angle. The blade

retains its balance if the same amount of material is

removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade

balancer (Fig. 36). 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 procedure until the blade

is balanced.

Important

The curved part of the blade must point

toward the inside of the mower.
