The difference between the dimensions obtained in

this dimension exceeds 1/8 inch (3 mm), the blade

WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace bent or damaged blade with
a new blade.
• Never file or create sharp notches in the
edges or surfaces of blade.
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. For 40 and 48 inch mower decks, remove the blade
bolt, curved washer, and blade from the spindle shaft
(Figure 65).
