A. If the difference between A and B is greater
than 3 mm (1/8 inch), replace the blade with
a new blade; refer to
Removing the Blades
(page 41) and Installing the Blades (page
42) .
Note:
If you replace a bent blade with a
new blade and the dimension obtained
continues to exceed 3 mm (1/8 inch), the
blade spindle could be bent. Contact an
Authorized Toro Dealer for service.
B. If the variance is within constraints, move to
the next blade.
6. Repeat steps 1 through 5 for each blade.
Removing the Blades
Replace a blade if it hits a solid object, if the blade
is out of balance, or if the blade is bent. For best
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.
1. Hold the blade end using a rag or thickly padded
glove.
2. Remove the blade bolt, curved washer, and
blade from the spindle shaft (
Figure 52 ).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both
ends of the blade (
Figure 53 ).
Note:
Maintain the original angle.
Note:
The blade retains its balance if you
remove the same amount of material from both
cutting edges.

1. Sharpen at the original angle.
2. Check the balance of the blade by putting it on a
blade balancer (
Figure 54 ).
Note:
If the blade stays in a horizontal position,
the blade is balanced and ready to use.
Note:
If the blade is not balanced, file some
metal off only the end of the sail area ( Figure 53 ).
