Abstract: A header has a cutterbar table that is movably mounted to a frame and configured to cut a standing crop, an intake auger mounted to the frame and configured to receive the cut crop; the intake auger further being configured to rotate, during a normal state, in a predetermined direction, and to rotate, during a corrective state, in a predetermined reversed direction, an actuator assembly configured to displace the cutterbar table relative to the frame, thereby changing a distance between the cutterbar table and the intake auger, a control unit configured to, upon receipt of an error signal indicative of a need to operate in the corrective state control the actuator assembly to displace the cutterbar table away from the intake auger to a safe operating position, prior to controlling the intake auger to rotate in the predetermined reversed direction.

Abstract: A folding crop header having an articulated, elongate crop divider defining upper and lower crop divider edges and having first and second crop divider sections, the crop divider including at or adjacent a said lower crop divider edge a hinge permitting pivoting of the first and second crop divider sections relative to one another about a first axis; and the crop divider including a linkage permitting pivoting of the first and second crop divider sections relative to one another about a second axis at or adjacent the said upper crop divider edge; and additionally permitting displacement of the first and second crop divider sections relative to one another in a displacement direction that is skewed relative to the second axis, the hinge being decouplable.

Abstract: A method and apparatus are disclosed for unblocking a perforated rotary filter screen. In the invention, at least one jet of high pressure air is directed at a surface of the filter screen as the filter screen is rotated and the or each jet of air is moved in a direction transverse to the direction of movement of the perforations in the screen in order to cause the or each air jet to trace a spiral or helical path over the surface of the screen.

Abstract: An active crop residue spreader for an agricultural combine including two horizontal rotor impellers for guiding and uniformly distributing the crop residue on a field, a triangular nose divider with a pyramidal shape which is wider at the base and an extension near or into the chopper. The spreader further comprises a straw guiding plate provided with specially shaped rakes on each side of the guiding plate.
