摘要：
A header assembly for a harvesting machine comprising a primary cutter head for cutting the crop, and a feeder for feeding the cut crop into the mouth of a crop processing mechanism. The assembly further comprises a secondary scissor-action cutter head trailing behind the primary cutter head for cutting stalks left behind by the primary cutter head, the secondary cutter head coupled to the rear of the header and supported by ground engaging rollers. The rollers include at least one support cylinder having a circumferentially discontinuous ground engaging outer surface operative to perform a preliminary processing of at least one of the crop residue and the soil.
