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.
