Checking for Bent Blades
1. Stop the engine, set the parking brake, remove the key,
and disconnect the spark plug wire(s) from the spark
plug(s).
2. Rotate the blades until the ends face forward and
backward (Fig. 25). Measure from a level surface to
the cutting edge of the blades (Fig. 26). Note this
dimension.

TING EDGE TO A LEV-

3. Rotate the opposite ends of the blades forward.
Measure from a level surface to the cutting edge of the
blades at the same position as in step 2 above. The
difference between the dimensions obtained in steps 2
and 3 must not exceed 1/8 inch (3 mm). If this
dimension exceeds 1/8 inch (3 mm), the blade is bent
and must be replaced; refer to Removing the Blades
and Installing the Blades, page 26.

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
The blades must be replaced if a solid object is hit, if the
blade is out of balance, or the blade 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 glove.
Remove the blade bolt, curved washer, and blade from the
spindle shaft (Fig. 27).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Fig. 28). Maintain the original angle. The
blade retains its balance if the same amount of
material is removed from both cutting edges.
