  • Patent number: 4113028
    Abstract: A lift device is mounted on a wheeled implement such as a disc harrow which has retractable wheels for transport. The lift device includes a pair of arms mounted on a horizontal pivot bar which is rotated by activation of the mechanism for lowering the wheels of the disc harrow. The arms hold a drawbar for a drag harrow when the drag harrow is to be transported and allow the drag harrow to hang vertically behind the disc harrow. In the suspended position, pivots in the arms allow the drag harrow considerable lateral freedom. When the arms are lowered, the drag harrow is released from the arms and dragged by pull lines. Hinges in the arms permit the arms to be folded up onto the disc harrow.
