Abstract
A crop conveying drum for a drive disc cutter is mounted directly to the drive shaft mechanism providing rotational power to the cutterbar. The crop conveying drum is formed as mating segments, each forming a half of the drum. Each segment has a pair of support bars vertically oriented and extending between connecting flanges. A mounting bracket centrally supported by the vertical support bars is formed to partially wrap around the drive shaft mechanism. The mounting bracket has holes therein for the passage of fasteners to connect the drum segment directly to the drive shaft mechanism so that the crop conveying drum rotates with the drive shaft mechanism. Upper and lower mating connecting flanges are fastened together to form the entire crop conveying drum rotatable with the drive shaft. The crop conveying drum assists in conveying severed crop material laterally from outlying disc cutters that define a cutting width of the cutterbar that is greater than the operating width of the conditioning rolls. The crop conveying drum is formed in an open configuration to allow the passage of severed crop through the drum so that severed crop cannot accumulate on the drive shaft mechanism to cause an unbalance therein and premature failure of the universal joints due to the wrapping of crop material.
