Cleaning Under The Belt Cover - Toro 22283 Operator's Manual

Sharpening the Blade
Service Interval: Every 50 hours—Sharpen or
replace the blade. Maintain it more
frequently if the edge dulls quickly in
rough or in sandy conditions.
File the top side of the blade to maintain its original
cutting angle (Figure 29A) and inner cutting edge
radius (Figure 29B). The blade will remain balanced if
you remove the same amount of material from both
cutting edges.
Figure 29
1. Sharpen the blade at this
angle only.
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 30).
Figure 30
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 82 N∙m (60 ft-lb).
