4. Rotate the opposite ends of the blades forward.
5. Measure from a level surface to the cutting
edge of the blades at the same position as
in step 3 above. The difference between the
dimensions obtained in steps 3 and 4 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.
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 (Figure 38).
