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.

Sharpening the Blades
1.
Use a file to sharpen the cutting edge at both ends of
the blade (Figure 59). Maintain the original angle. The
blade retains its balance if the same amount of material
is removed from both cutting edges.

Sharpen at original angle
2.
Check the balance of the blade by putting it on a blade
balancer (Figure 60).
3.
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 (Figure 57)
4.
. Repeat this procedure until the blade is balanced.
