An agricultural baler includes a feeder duct communicating with a bale chamber for charges of crop material to be transferred into a bale chamber. The baler also includes a door that defines at least a portion of a bottom wall of the feeder duct. The door is movable between: (i) a door-open-position, in which an opening in the bottom wall is provided; and (ii) a door-closed-position in which the opening is closed. The baler further includes a pick-up device that is movable between: (i) a lowered-position in which it is operable to convey crop material into the feeder duct; and (ii) a raised-position in which it is spaced further away from the ground than in the lowered-position. The pick-up device is mechanically coupled to the door of the bottom wall such that movement of the pick-up device causes the door to move from the door-open-position to the door-closed-position.

A residue handling system of an agricultural harvester includes a straw beater for receiving material other than grain from a threshing and separating system. A subsequent residue treatment device receives the material from the straw beater and breaks down larger parts of the material prior to discharge from the agricultural harvester. At least one wind generating system is located at an end of the straw beater and directs a flow of air from the vicinity of the straw beater to the subsequent residue treatment device. The flow of air is directed to pass substantially through an upper rearward part of the residue handling system. The flow of air operates to further entrain, render airborne, and transport material other than grain proceeding from the straw beater to the subsequent residue treatment device.

A grain separating apparatus (1) for a combine harvester (2). The grain separating apparatus (1) has at least a first walker-sieve (3) and a second walker-sieve (4) arranged side by side, wherein the first walker-sieve (3) and the second walker-sieve (4) are suspended in at least two suspension points (5,6) in the combine harvester (2) and wherein at least one of the two suspension points (5,6) is arranged to describe a rotational motion. A rotational motion drive (7) is arranged to drive the rotational motion of the first walker-sieve (3) out of phase with the rotational motion of the second walker-sieve (4), wherein each of the at least two walker-sieves (3,4) include a straw walker (8) comprising drivers (9) for conveying a straw material (10) and wherein grain (11) and debris (12) are separated from the straw material (10) through walker apertures (13) arranged in the straw walker (8). Furthermore, the straw walker (8) is arranged on top of at least one sieve (14,15) which is arranged to separate grain (11) from the debris (12) and wherein the straw walker (8) and the at least one sieve (14,15) are rigidly connected. Furthermore, a method for separating grain (11) from straw material (10) in a combine harvester (2) by a grain separating apparatus (1) as described above.

An agricultural harvester includes a threshing and separating system for separating grain from non-grain crop material, and a residue handling system for receiving at least a portion of the non-grain crop material. The residue handling system includes a chopper and a windrow arrangement, each having an inlet. A door is movable between a closed position which directs the non-grain crop material to the chopper and an open position which directs the non-grain crop material to the windrow arrangement. A feed roller is positioned adjacent to and between the inlet of the chopper and windrow arrangement. The feed roller is rotatable in a first direction which directs the non-grain crop material to the chopper when the door is in the closed position, and a second direction which directs the non-grain crop material to the windrow arrangement when the door is in the open position.
