Correcting The Mower Quality Of Cut - Toro 38096 Operator's Manual

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.
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 (Figure 51).

of the blade (Figure 52). Maintain the original angle.
The blade retains its balance if the same amount of
material is removed from both cutting edges.

2. Check the balance of the blade by putting it on a
blade balancer (Figure 53).
3. If the blade stays in a horizontal position, the blade
