Removing the Blades

The blades must be replaced if a solid object is hit, if the
blade is out of balance, or the 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 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
