A. If the difference between A and B is greater than
3mm (1/8 inch), replace the blade with a new
blade; refer to Removing the Blades (page 37) and
Installing the Blades (page 38).
Note: If a bent blade is replaced with a new one,
and the dimension obtained continues to exceed
3mm (1/8 inch), the blade spindle could be bent.
Contact an Authorized Toro Dealer for service.
B. If the variance is within constraints, move to the
next blade.
Repeat this procedure on each blade.
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. 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, the curved washer, the blade
stiffener, and the blade from the spindle shaft (Figure
50).
