Claim:
1 . A harvesting header, comprising: a cutter bed having a cutter mechanism to cut crop material; a discharge opening through which the cut crop material passes as it moves rearwardly in the header; at least one conditioning roll placed forward of the discharge opening so as to condition crop material cut by the cutter mechanism before it passes through the discharge opening; and a helper roll parallel to and having a length greater than that of the conditioning roll and discharge opening, said helper roll having an interior portion configured to urge the crop material rearward toward the conditioning roll and outer portions with auger flights configured to urge the crop material laterally inward toward said at least one conditioning roll and discharge opening, wherein said helper roll comprises first and second sub-helper rolls with a coupling mechanism coupling said second sub-helper roll to said first sub-helper roll such that said first and second sub-helper rolls have a common axis and so that rotation of the first sub-helper roll causes rotation of the second sub-helper roll, said coupling mechanism comprising a shaft received by said first and second sub-helper rolls; and a support attached to the cutter bed, said support having a bearing assembly rotatably supporting the shaft of the helper roll.
