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 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
on page 33.
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.

removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 43). If the blade stays in a horizontal
