    Abstract: A harvester and trimmer for carrots, which can also be used on root crops such as red beets, turnips, parsnips and rutabaga, embodies a wheeled vehicle having a conventional plowshare and an upwardly and rearwardly extending harvesting frame. The harvesting frame mounts opposed endless harvesting or lifter belts having adjacent reaches for grasping and lifting the tops of the plants. A pair of laterally opposed gauging belts is disposed above a downstream portion of the lifter belts and these belts are upwardly and rearwardly inclined from the lifter belts at an acute angle of about 6-7 degrees for independently grasping the tops to pull the tops up through the underlying lifter belts, bringing the crowns of the roots against the lifter belts.

  • Patent number: 4162097
    Abstract: A vehicle construction comprising a vehicle frame, spaced apart wheels on the frame, and an operator cab mounted on the frame between the wheels. The cab has an access door with generally vertically extending sides adjacent to one of the wheels and the door has a lower extremity below the uppermost extent of the adjacent wheel and a relief in one side thereof at the lower extremity of the door. A generally horizontally directed link is within the cab and has one end pivoted to the cab at a location intermediate the sides of the door and an opposite end pivoted to the door on the interior surface thereof between the side having the relief and the intermediate location at which it is connected to the cab. There is a horizontally slidable connection between the door adjacent the side having a relief thereon and the cab so that when the door is opened, the door will rotate and be translated to allow the lower extremity to clear the wheel and permit the door to fully open.
