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.
