Abstract
Two sickles, each slightly longer than half the width of the swath taken by the mower, are supported across the front of the mower for reciprocation in mutually opposite directions. Although the two sickles are located in the same vertical plane, they are situated in two different horizontal planes so as to permit overlap in the center during reciprocation. To further facilitate such overlap, the backing bar to which the knife sections of one sickle are attached is located on top of the sections, while on the other sickle, the backing bar is located along the bottom of the sections. The sections are so arranged adjacent the inner ends of the sickles that even when the sickles are at the extremes of their outward strokes away from one another, no gap is presented in the center between the two innermost sections of the two sickles, thereby promoting even cutting across the entire swath taken by the sickle assembly.
