ABSTRACT:
A rotary crop feed assist device mounted on a divider of a row crop harvesting header has a plurality of angularly spaced crop-engaging members projecting radially from a forwardly inclined rotational axis. The crop-engaging members are connected together at inner longitudinally-extending portions and have outer longitudinal edges which taper downwardly and inwardly toward the rotational axis. Their outer longitudinal edges sweep along a rotational path in the shape of an inverted truncated cone upon rotation of the device to impose a downward force on the crop material as it is being pulled into the discharge end of the row crop header past the feed assist device. In an modified embodiment, teeth-bearing extension members are fastened on the crop-engaging members and adjustable thereon toward and away from the rotational axis to vary the degree of exposure of the teeth in the row thereof past the outer longitudinal edges of the crop-engaging members and thereby the aggressiveness of the longitudinal edges in assisting the feeding of crop stalk material past the rotary device.
