Removing the Blades
The blades must be replaced if a solid object is hit, 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.

If the blade is not balanced, file some
metal off the end of the sail area only (
