Abstract
A rotary disc cutterhead knife mounting system uses a spring plate bolted to the underside of the cutterhead cover. A knife pin is attached also to the underside of the cover, adjacent the outer edge thereof, and extends downwardly therefrom. The knife has a mounting hole therethrough, slightly larger that the diameter of the knife pin. With the knife hole fitted on the knife pin, the spring plate compresses the knife toward the underside of the cover; holding the knife in operating position. A special tool is used to remove the knife by forcing the spring plate downward, freeing the knife.
