ABSTRACT:
A hopper bottom for supporting a grain bin includes a frustro conical hopper bottom wall with a discharge opening at a central base. Around the periphery of the wall is provided a plurality of vertical legs which support the wall above a horizontal support surface. The legs are formed square tubing with a hinge part way along the leg so as to divide the leg into an upper fixed stub portion and a lower pivotal main portion. The hinge is positioned inside the inside surface of the leg so that the main portion can fold to a position extending inwardly and downwardly. The hinge includes a pair of plates welded to the upper and lower ends of the main and stub portions. The plate at the bottom of the stub portion extends outwardly from the leg with a downturn flange at its outermost end so that the upper edge of the lower hopper bottom can engage against the underside of the outwardly projecting portion allowing the hopper bottom to be stacked for transportation while the legs remain attached to the hopper bottom but folded inwardly.
