Removing the Blades

Replace a blade if it hits an object, if the blade is out of balance,

or if 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 nonconformance with safety
standards.
1. Hold the blade end using a rag or a thickly padded
glove.

the blade

same amount of material from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer
