  • Patent number: 4355713
    Abstract: Apparatus for lifting produce-filled cartons from an agricultural field. A main frame has a pickup device at its forward end, comprising a pair of rotating facing discs on two generally vertical converging planes with high friction faces for engaging the carton side walls. A gripping device behind the pickup device comprises a substantially coplanar pair of rotatable yieldable tired wheels facing each other and inclined rearwardly upwardly, the tires providing high friction surfaces for engaging the carton side walls. The gripping device is located so that it positively takes away the carton from the pickup device and supports it while conveying it rearwardly and upwardly to a conveyor means that moves the carton upwardly and rearwardly therefrom.
