ABSTRACT:
Agricultural hopper structure for containing two different granular materials such as seed and fertilizer. Two molded plastic containers are nested together and supported on a frame. The nested ends of the containers are concave and convex, respectively, to provide a symmetrical appearance while establishing unequal container capacity. The nested containers include a downwardly directed ledge structure freely resting on a corresponding upwardly facing load-bearing surface of the frame to reduce the number of fixed attaching points. The upper portions of the containers extend above the frame and have outwardly convex sidewalls. The hopper structure is fabricated by first nesting the containers and then lowering the nested containers onto the frame.
