A mobile hopper assembly is towable by a vehicle and includes a frame, a hopper that is fixedly attached to the frame, a leg that is attached to the frame, and a wheel that is coupled to the frame. The leg includes a movable portion that is movable with respect to the frame between a retracted position and an extended position, and the wheel at least partially supports the mobile hopper assembly when the leg is in the retracted position.
