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 38).
Figure 38
Note: You can also check the balance using a
commercially manufactured blade balancer.
2. If either end of the blade rotates downward, le that
end (not the cutting edge or the end near the cutting
edge). The blade is properly balanced when neither
end drops.
Installing the Blade
1. Install a sharp, balanced Hayter blade, the anti-scalp
cup, and the blade nuts. The sail of the blade must
point toward the top of the mower housing for
proper installation. Torque the blade nuts to 23 to
27 ft-lb (32 to 37 N•m).
2. Return the mower to its operating position.
3. Connect the wire to the spark plug.
