Installing The Blades - Toro TimeMaster 21199HD Operator's Manual

Installing the Blades

1. Install the first blade so that it is horizontal, along
with all mounting hardware as shown in
35.
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 36; torque the blade bolt to 82
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
Figure
1. Blade (2)
4. Tighten the second blade; refer to step 2.
5. Rotate the blades by hand a full 360° turn to
ensure that they do not touch.
Note:
not mounted correctly. Repeat steps
3, until the blades no longer touch each other.
WARNING
Incorrectly installing the blades could damage
the machine or cause an injury to you or
bystanders.
Use care when installing the blades.
