Abstract:

An agricultural sweep which includes a pair of divergent wings having sharpened, earth-cutting edges. The wings define an angle of between 60. degree. and 100. degree. , and a hard metal insert is used to provide an overlying cap at the forward end of the two wings where the wings converge and extend toward a leading point. The pointed forward ends of the two wings are cut away, and a point carried by the insert is inserted in the space which remains after the pointed forward ends of the two wings have been removed. The insert tapers to a ridge or crest which lies in a plane which bisects the sweep, so that the wings lie on opposite sides of the bisecting plane.
