Abstract: A feed box includes a chamber defined by oppositely positioned downwardly and inwardly sloping end walls, a vertical side wall and a bottom wall extending downwardly and laterally across said box to the vertical side wall. The vertical side wall may have a slight laterally inward slope to it. A discharge opening is provided in the bottom wall adjacent the vertical side wall and a spout is positioned under the bottom wall opening to direct material flowing from the chamber back towards the longitudinal centerline of the box. The vertical side wall also includes a discharge opening at its lower end and a spout is provided to receive material from the box chamber for directing it laterally away from the box in the opposite direction from the spout associated with the bottom wall opening. Closure gates are provided for each of the discharge openings in the bottom wall and side wall.
