Leveling The Mower Deck - Toro 74661 Operator's Manual

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

of material is removed from both cutting edges.
