Cleaning; Cleaning Under The Mower Housing - Toro 22291 Operator's Manual

Balancing the Blade
1. Check the balance of the blade by placing the center
hole of the blade over a nail or screwdriver shank
clamped horizontally in a vise (Figure 23).
Figure 23
Note: You can also check the balance using a
commercially manufactured blade balancer.
2. If either end of the blade rotates downward, file that
end (not the cutting edge or the end near the cutting
edge) until neither end of the blade drops.
Installing the Blade
1. Install a sharp, balanced Toro blade, the accelerator, the
lock washer, and the blade bolt. The sail of the blade
must point toward the top of the mower housing for
proper installation.
Note: Torque the blade bolt to 68 N-m (50 ft-lb).
WARNING
Operating the machine without the accelerator
in place can cause the blade to flex, bend, or
break, resulting in serious injury or death to
you or to bystanders.
Do not operate the machine without the
accelerator in place.
2. Return the machine to the operating position.
