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 43.

2. Remove each blade as shown in
Figure 44

Installing the Blades
1. Install the first blade so that it is horizontal, along
with all mounting hardware as shown in
44.
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
N∙m (60 ft-lb).
Important:
A bolt torqued to 82 N∙m (60
ft-lb) is very tight. Put your weight behind
the wrench and tighten the bolt securely.
This bolt is very difficult to overtighten.
3. Rotate the installed blade 1/4 turn until it is
vertical, and install the other blade in the same
manner as the first (refer to step 1).
Note:
The blades should be perpendicular,
forming an inverted "T" as shown in
26
45; torque the blade bolt to 82
