Abstract
A grain wagon includes a wheel supported frame supporting a container having inclined front and rear walls connected by opposite inclined side walls. Each side wall has inwardly projecting wall portions defining a wheel well for receiving longitudinally offset dual wheels or extra wide wheels. The rear wall includes a portion sloping between the wheel well wall portions to a forward grain removal zone, and generally triangular diverter walls extend from the rear wall to the wheel well wall portions. A corner discharge auger conveyor extends from the grain removal zone and has an upper portion which pivots to a stored position adjacent the front wall of the container. The dual wheels are positioned within the wheel wells by support members having end portions pivotally connected to the wagon frame and opposite end portions connected to the frame by laterally slidable clamping plates.
