ABSTRACT:
An improved crop conveying drum for a drive disc cutter mounted directly to the drive shaft mechanism providing rotational power to the cutterbar. The crop conveying drum includes a pair of mating segments, each forming a half of the drum. Each segment is formed from a single piece of plate material and stamped into the desired curvilinear configuration. A central mounting portion of each segment is contoured to match the drive shaft mechanism and allow connection thereto. Holes in the central mounting portion allow insertion fasteners to connect the drum segments directly to the drive shaft mechanism so that the crop conveying drum rotates in unison with the drive shaft. By forming the drum segments from a single plate of material, material characteristics can be more easily selected or more quickly modified compared to the fabricated weldments known in the art.
