Installing The Blades - Toro TimeMaster 21199 Operator's Manual

Installing the Blades

1. Install the first blade so that it is horizontal, along with
all mounting hardware as shown in
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
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 44.

mounted correctly. Repeat steps
blades no longer touch each other.

machine or cause an injury to you or bystanders.
