HEADER ASSEMBLY FOR A HARVESTING MACHINE

摘要

A header assembly (10) is described for a harvesting machine having a header (12) comprising a primary cutter head (14) for cutting the crop, and a feeder (15) for feeding the cut crop into the mouth of a crop processing mechanism. The assembly further comprises a secondary scissor-action cutter head (16) trailing behind the primary cutter head (14) for cutting stalks left behind by the primary cutter head, the secondary cutter head being coupled to the rear of the header (12) and supported by ground engaging rollers. In the invention, the rollers include at least one support cylinder (22) 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.
