Abstract: A header for a combine harvester has a primary implement, a secondary implement and a link that is connected with the secondary implement. The header further has a lifting device with a slide element that is formed and connected with the link so that a translational movement of the slide element causes a lifting of the secondary implement relative to the primary implement.

Abstract: 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.

Abstract: An agricultural machine suitable for the harvesting of grain-like crops, comprising a header, the header comprising a first cutting device whose position is determined by the adjustable height of the header, and a second cutting device, comprising a knife drum that is rotatably mounted in a housing, which via rollers or equivalent supports can move over the ground at different heights of the header, and wherein the housing of the knife drum on the back of the header is connected via at least two coupling systems, each of these systems comprising a lower and an upper support arm pivotally connected to the header, and with the housing of the knife drum, whereby the position of the housing remains substantially unaltered by the different height settings of the header.
