ABSTRACT:
A V-shaped under frame with a transverse rear member connected at its ends to forwardly converging side members has spaced uprights connectable to a truck. Pivots connected in aligned relation on each side member connect to ribs on the convex rear side of right and left moldboards. The inner edges of the moldboards are closely adjacent along their upper portions, but diverge along their lower portions. Backing springs on the side members bias the tops of the moldboards forwardly. A low V-shaped plow point is connected by a strut to the under frame and located within the space left by the diverging lower portions of the moldboards. Roadway engaging shoes are connected to the under frame adjacent each of its three corners.
