Abstract: A conditioning roller assembly includes two conditioning rollers which are rotatably mounted on associated bearing arrangements, and a holder which includes a first holder component and a second holder component that are connected together by a hinge and a spring arrangement for providing a pre-tensioning of the conditioning rollers. The first holder component is releasably connected to the first bearing arrangement, the second holder component is releasably connected to the second bearing arrangement, and the conditioning rollers, with the bearing arrangements, are detachable in each case from the components without the holder being disassembled.

Abstract: A system for lubrication of a bearing of a crop transport and/or processing system of a harvesting machine includes a supply container for storing a lubricant, a delivery pump and a lubricant line for delivering the lubricant from the supply container to the bearing, and a drainage channel and a suction pump for returning the lubricant from the bearing to the supply container.

Abstract: The invention relates to a feeding device (32) for a field chopper (10), comprising: at least one rotatable lower feedroll (34, 35), at least one rotatable upper feedroll (36, 37), between which a windrow can be fed and led to a chopping device (22), and an external force-activated adjustment drive (68), with which the position of at least one of the feedrolls (36, 37) can be changed relative to the other feedroll (34, 35). It is proposed that a spring (58) be arranged between the adjustment drive (68) and the feedroll (36, 37) that can be moved by this drive. The spring (58) enables the movable feedroll (36, 37) to react more quickly or immediately to sudden changes in windrow height independent of the inertia of the adjustment drive (68).
