Abstract: Apparatus for unrolling roll bales of crop material includes an apron having a horizontal section and an upwardly inclined section at each end of the horizontal section. A finger drum is located adjacent the intersection of the horizontal section and one of the upwardly inclined sections of the apron. The apron is movable in a direction to move a roll bale resting thereon into contact with the finger drum so that the roll bale will be gradually unrolled as it is rotated. Material removed from the roll bale will be carried up one of the inclined sections of the apron to a suitable height for delivery into a feed trough while the other inclined section of the apron prevents the bale from rolling off the apron.

Abstract: A pickup attachment for use on crop harvesting machines wherein the pickup attachment includes a reel with a plurality of fingers connected to and rotatable about a central shaft in a predetermined path to pick up crop material. The pickup attachment is supported at one side by a wheel and at the other side by a roller positioned underneath the pickup attachment. The wheel is arranged with its center located substantially in alignment vertically with the axis of the reel central shaft while the roller is arranged with its center located rearward of the axis of the reel central shaft. This arrangement of the wheel and the roller allows the path of the reel fingers to follow the contour of the ground in proximity thereto when the pickup attachment is operated over rough or uneven terrain.

Abstract: A row crop attachment has row crop dividers which are independently adjustable for varying widths of row crops. Protruding crop guide members which are mounted for width adjustment with the dividers are also adjustable independently of the dividers and the guide members are relatively adjustable for both width and height adjustment.

Abstract: A multi-row crop header for a harvesting machine has a plurality of fore-and-aft extending row crop units, each having an elongated passageway with a front inlet opening and a rear discharge opening. The row crop units are pivotally mounted such that they can be swung toward and away from one another so as to vary the lateral distance between the inlet openings of adjacent units to thereby accommodate crops planted in various width row spacings.
