Abstract

A vehicle including a combination body for selectively dumping and spreading materials. The vehicle includes, at least, a chassis and a body pivotably secured to the chassis at a hinge. The body is comprised of front and rear ends having upper and lower edges and first and second side walls having lower edges. A hoist is provided which extends between the body and the chassis for pivoting the body about the hinge. A conveyor assembly is also included, the assembly comprising an endless conveyor disposed adjacent to at least a portion of the lower edges of the side walls and extending beyond the rear end of the body; a tailgate pivotably connected to the rear end of the body and having an opening therein to permit material to be transported therethrough by the endless conveyor, the tailgate being selectively pivotable with respect to the body about a lower axis disposed adjacent the lower edge of the tailgate or about an upper axis disposed adjacent the top edge of the tailgate; a cover assembly extending rearwardly from the tailgate which is pivotably attached to the tailgate at a pivot axis, wherein the cover assembly rotates about the pivot axis upon contact with the conveyor assembly when the tailgate pivots about the lower axis; and a spreader cooperating with the conveyor assembly for spreading the material.
