Abstract: A bulk material storage bin and a floor structure for such a bin for storing grain or like bulk commodities. The floor structure of the bin has downwardly converging side walls preferrably having a smooth surface. In a preferred embodiment, the floor structure is conical in shape with a downwardly directed apex. As bulk material is emptied from the storage bin, it travels down the side walls of the floor to the apex where it is conveyed outwardly. Piles of residual bulk material are not accumulated along the floor structure.

Abstract: A tank attached with a mounting bracket to the rear drive unit of a four-wheel drive tractor. The tank has a one-piece plastic body providing a chamber for accommodating a liquid. The top of the body is covered with a rearwardly and downwardly sloping plastic top wall to enhance the visibility of the tractor operator. A plurality of ribs on the bottom wall and top wall project into the chamber on opposite sides of upright baffle plates. A liquid return structure located in the chamber and mounted on the back wall of the body discharges return liquid to opposite end sections of the chamber.
