WARNING
A blade that is bent or damaged could
break apart and could critically injure you or
bystanders.
• Always replace a bent or damaged blade
with a new blade.
• Do not file or create sharp notches in the
edges or surfaces of the blade.
Removing the Blades
Replace the blades if they hit a solid object, if a blade is out of
balance, or if a 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 nonconformance with
safety standards.
