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.
A. If the difference between A and B is greater
than 1/8 inch (3mm) replace the blade with a
new blade. Refer to Removing the Blades and
Installing the Blades.
Note: If a bent blade is replaced with a new one
and the dimension obtained continues to exceed
1/8 inch (3mm), 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.
Repeat this procedure on each 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.
Hold the blade end using a rag or thickly-padded glove.
Remove the blade bolt, curved washer, and blade from
the spindle shaft (Figure 66).
