blade with a new blade.
• Never file or create sharp notches in
the edges or surfaces of blade.
Removing the Blade
The blade 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. A replacement blade
made by other manufacturers may result in
non-conformance with safety standards.

thickly-padded glove.

(Figure 48). Repeat this procedure until the
blade is balanced.
