ABSTRACT:
A plow sweep is provided including a shovel body defining a central front to rear extending axis and having a pair of first and second rearwardly divergent blade arms disposed on opposite sides of the central axis and joined at their forward ends along the axis to define a forward apex of the sweep. The arms are transversely rearwardly and upwardly inclined and the rear portion of the apex includes an integral upwardly directed mounting shank portion. The rear end of at least one of the arms terminates in an oppositely forwardly angulated blade-type wing arm. The forward edges of the arms are sharpened and the latter are also transversely rearwardly and upwardly inclined. The portions of the wing arm or arms and the corresponding blade arms adjacent the juncture thereof have their rear edge portions downwardly depressed into at least generally horizontal front to rear extending positions and the forward end of each wing arm may be provided with an upstanding front to rear extending vane having a forward upstanding edge which is also sharpened.
