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.
Checking for Bent Blades
,
Rotate the blades until the ends face forward
and backward (Figure 36). Measure from a
level surface to the cutting edge, position A, of
the blades (Figure 36). Note this dimension.

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 1. The difference between the dimensions
obtained in steps 1 and 2 must not exceed
1/8 inch (3 ram). If this dimension exceeds
1/8 inch (3 ram), the blade is bent and must be
replaced. Refer to Removing the Blades and
Installing the Blades.
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 safer) Tconformance 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,
blade stiffener, and blade from the spindle shaft
(Figure 37).

Sharpening the Blades
,
Use a file to sharpen the cutting edge at both
ends of the blade (Figure 38). Maintain the
original angle. The blade retains its balance if
the same amount of material is removed from
both cutting edges.
