ABSTRACT:
A crop hold down arrangement for a pick-up comprises a roll supported by means of pivot arms from the frame so as to enable the arms to pivot vertically and guide the roll in the direction of crop being fed by a tined pick-up drum to a conveyor in response to an increase in the height of a crop windrow being picked up. A chain is provided between the frame and roll-support arm to limit the downward travel of the arm so as to keep the roll from interfering with the tined pick-up drum. A spring assembly is provided for counterbalancing at least a portion of the weight of the arm and roll assembly so that the roll will easily rise over a relatively light and fluffy crop windrow.
