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 (rotating it counter-clockwise), curved
washer, and blade from the spindle shaft
