Removing The Mower - Toro 170-DH Operator's Manual

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
each blade (Fig. 36). 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 each blade by putting it on a blade
balancer (Fig. 37). 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 back side
of the blade. Repeat this step until each blade is
balanced.
