ABSTRACT:
A power operated sickle is provided having a plurality of stationary guards projecting forwardly from a sickle bar with relatively narrow guide channels between them wherein the channels between the guards have a length-to-width ratio on the order of about 2/1 or greater, the center distances between the guards are about twice the width of the channel between the guards and the cutting teeth cooperating with the guards are pitched to extend laterally a distance of about 1/3 the distance between the centers of the guards whereby an angle of less than about 20.degree. is established between the cutting edges of the teeth and the cooperating side edges of the guards. The centers of the guards are spaced less than about 2" apart and each guard includes longitudinally extending downwardly projecting keel with a height on the order of about two times the width of the guard to provide an improved overall geometrical configuration for increasing cutting capacity while at the same time reducing the tendency of material to clog the sickle.
