2. Rotate the opposite ends of the blades forward.
3. Measure from a level surface to the cutting edge of the
blades at the same position as in step 1. The difference
between the dimensions obtained in steps 1 and 2 must
not exceed 1/8 in. (3 mm) If this dimension exceeds
1/8 in. (3 mm), the blade is bent and must be replaced.
Refer to Removing the Blades, and Installing the
Blades on page 40.
Warning
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of blade.
Removing the Blades
Blades must be replaced if a solid object is hit, if the
blade is out of balance or is bent. To ensure optimum
performance and continued safety conformance of the
machine, use genuine TORO replacement blades.
Replacement blades made by other manufacturers
may result in non-conformance with safety standards.
Hold the blade end using a rag or thickly-padded

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Fig. 50). 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. 51). 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
until the blade is balanced.
