ABSTRACT:
A crop gathering attachment for an agricultural harvester having a rotatable auger-like conveyor for transporting crop material, a stationary crank shaft mechanism enclosed in the conveyor and having a shaft portion disposed eccentrically and parallel to the rotational axis of the conveyor, and a retractable finger arrangement comprising a plurality of finger members pivotally connected at their inner ends to the shaft portion and projecting outwardly through guiding members provided in the peripheral wall of the conveyor. The finger arrangement is timed such that due to the eccentric disposition of the shaft portion, the finger members are reciprocated relative to the conveyor wall upon rotation of the conveyor, thereby protruding from the wall at one side of the conveyor for projecting into the crop material and being retracted relative to the wall at the generally diametrically opposed side of the conveyor for releasing the transported crop. A unique actuator is operatively connected to the crank shaft mechanism for remotely controlling the position of the shaft portion relative to the conveyor and thereby varying the timing of the finger members.
