(3 mm), the blade is bent and must be replaced;
refer to Removing the Blades (page 22) and
Installing the Blades (page 22).
WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace a bent or damaged blade with
a new blade.
• Never file or create sharp notches in the
edges or surfaces of a blade.
Removing the Blades
Replace the blades when the machine hits a solid object
or when a blade is out of balance or bent. Use only
genuine Toro replacement blades.
1. Use a block of wood to hold each blade steady and
turn the blade bolt counterclockwise as shown in
Figure 44.
2. Remove each blade as shown in Figure 45.

3. Inspect the pins on the blade drivers for wear and
damage.
Installing the Blades
1. Install the first blade so that it is horizontal, along
with all mounting hardware as shown in Figure 45.
Note: Tighten the bolt with your fingers.
Important: Position the curved ends of the
blades to point toward the machine housing.
Be sure to nest the raised areas on each blade
driver with the recesses in the head of its
corresponding spindle, and the pins on the other
side of each blade driver with the holes in its
corresponding blade.
2. Steady each blade with a board and turn the blade
bolt clockwise with a torque wrench as shown in
Figure 46; torque the blade bolt to 60 ft-lb (82 N-m).
Important: A bolt torqued to 60 ft-lb (82 N-m)
is very tight. Put your weight behind the wrench
and tighten the bolt securely. This bolt is very
difficult to overtighten.
