Abstract: The cleated belt forage conveyor of the invention is directed to a forage belt conveyor in which the belt in service is protected against side discharge of conveyed forage by upstanding and intermittent central cleats and outwardly spaced side cleats. Sealing strips extend above the belt in the spaces between the respective central and side cleats to limit outward movement of the bulk of the forage and an edging extends on each side of the belt to prevent spillover. In the event of some side discharge from the belt to the inside of the lower reach of the belt, a plow overlying the inside of the lower reach of the belt directs the forage for discharge to vibrating deflector plates which deflect the forage to the bottom of the housing of the conveyor to be carried by the cleats to the input side of the conveyor and around the idler pulley for reconveyance.
