Removing the Blades
Installing the Blades (page
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.
1. Hold the blade end using a rag or thickly padded
glove.
2. Remove the blade bolt, curved washer, and
blade from the spindle shaft
