Aiding in conveying crop to the discharge passage are right- and left-hand sets of three crop converging drums provided at each side of the discharge passage. The outer drums of the two sets are respectively mounted to the top of the right- and left-hand end cutting units of the cutter bar while the other two drums on each side are located behind an inward and rearward extending line that is tangent to the cylindrical path traced by the outer and inner ones of the drums on each side of the discharge passage. In one embodiment, a direct drive transmission is provided, and in a second embodiment a hydraulic motor is provided, for driving the inner two converging drums of each set.
In a crop harvesting platform including opposite, fore-and-aft extending side walls, a transverse rotary cutter bar extending between said side walls and equipped with a plurality of rotary cutting units including at least right- and left-hand end cutting units and right- and left-hand second cutting units respectively located beside said right- and left-hand end cutting units and operating together with said end cutting units for delivering crop to a centrally located discharge zone between said right- and left-hand second cutting units, right- and left-hand outer crop converging drums respectively being mounted for rotation with said right- and left-hand end cutting units, and right- and left-hand second crop converging drums being respectively located inwardly and to the rear from said right- and left-hand outer crop converging drums, the improvement comprising:
