Abstract: A vehicle is shown having a hopper mounted thereon capable of dumping materials contained within the hopper over the end of the hopper or through the bottom of the hopper. Dumping over the end of the hopper is accomplished by lifting the front end of the hopper and sequentially pivoting the rear end of the hopper upon an initial pivot point and a subsequent pivot point in a manner which minimizes the risk of the vehicle capsizing by maintaining a low center of gravity. Dumping through the bottom of the hopper is accomplished through the use of a clam shell gate covering an opening in the bottom of the hopper. The vehicle may be interchangeably used as a rear dump vehicle or a belly dump vehicle, more safely used upon hazardous terrains, and still carry the maximum load capacity allowed.
