An agricultural residue chopper assembly comprising: a cutting chamber housing with cutting knives rotatable along a cutting direction within the cutting chamber, and a rotatable counterknife shaft unit. The shaft unit is mounted at a rotation axis near an outer surface of the cutting chamber housing, and has an outer face and one or more counterknives extending outward from the outer face. The shaft unit is rotatable to move the counterknives closer and further from the cutting knives' rotation axis. The outer face and the outer surface of the cutting chamber housing define a trailing area in which a gap distance between the outer face and the outer surface of the cutting chamber housing remains constant or increases in size as the counterknife shaft unit is rotated to move the counterknives closer to the cutting blade axis. An agricultural harvester machine having a residue chopper assembly is also provided.

The present invention relates to a spreading arrangement (10) adapted to be arranged after a combine harvester (1), said spreading arrangement comprises two spreader fans (8), two flow guides (21), and two flow diverting elements (23). An inlet (27) of each one of the two flow guides (21) are arranged in proximity to a respective one of said spreader fans (8), an outlet (28) of said flow guides (21) are provided at a distance from said respective inlets. Each one of said two flow diverting elements (23) are provided at a respective one of said outlets (28) of said guide elements (21) and are adapted to be adjustable between at least a first and a second position. The present invention also relates to a combine harvester (1) being provided with a spreading arrangement (10).

A combine harvester has a straw chute with a straw conveyor which comprises a conveyor rotor which can be set into rotation and has dogs distributed helically around the conveyor rotor.

A cutting assembly is described that comprises two oppositely facing sidewalls and two loading systems, each loading system comprising a transverse member that extends between and through the sidewalls, and two trays of knives. Rotation of a transverse member causes the associated tray of knives to move between a loaded and an unloaded position, wherein the loaded position the knives protrude into a crop collection channel of a harvester for the cutting of crop material.

The chopper assembly includes a rotatable chopper drum having a plurality of knives mounted between two sidewalls and configured to cut larger plant material into smaller particles through the interaction of the knives and a set of counterknives. A guide surface is mounted on at least one of the sidewalls, preferably on both sidewalls, and in the path of a stream of crop material advancing towards the chopper assembly. The guide surface extends between an upstream edge lying essentially in the plane of the sidewall and a downstream edge removed from the sidewall. The guide surface is furthermore inclined relative to the sidewall, so as to guide plant material away from the sidewall and in the direction of the knives located closest to the sidewall. The guide surface thereby prevents plant material from passing between the knives and the sidewall without being cut.
