Abstract: The spreader system includes two spreader rotors configured to rotate about upright rotation axes and to eject residue crop material centrally between the spreader rotors in a direction tangential to the spreader rotors. A deflector configuration including a first and second curved deflector blade is arranged to deflect crops ejected respectively by the first and second rotor, into respective first and second ejection directions. The deflector blades are pivotable about upright pivot axes, to adjust the ejection directions. A sensing arrangement is configured to sense local spreading patterns in a first and second adjustable sensing direction, measure the angular positions of the deflector blades by suitable measuring devices, and adjust the first and second sensing directions so as to correspond to the first and second ejection directions of the crop residue. A control unit is configured to receive signals representative of the local spreading patterns and of the angular positions.

Abstract: The invention provides a positioning apparatus (17) for a rotary combine harvester (100) having a threshing concave (6a) and a separation grate (6b). The apparatus (17) has a concave adjustor mechanism for adjusting a threshing gap between the threshing concave (6a) and a rotor or rotors (5) of the harvester (100). The concave adjustor mechanism has a concave actuator (33) including a concave hydraulic cylinder having an adjustable hydraulic pressure to cause rotation of a concave control arm (31) so as to control a position of the threshing concave (6a). The apparatus (17) also has a grate adjustor mechanism for adjusting a separation gap between the separation grate (6b) and the rotor or rotors (5) of the harvester (100). The grate actuator mechanism has a grate actuator (330) including a grate hydraulic cylinder having an adjustable hydraulic pressure to cause rotation of the grate control arm (310) so as to control a position of the separation grate (6b).

Abstract: A method for automatically controlling a harvesting parameter on a header of a combine harvester. The combine harvester includes the header, a feeder, and a downstream processing device. Crop is cut by the header, transferred to the feeder, and then transported to the processing device.

Abstract: A square baler having a control system including at least one density sensor for measuring the relative density of crop slices within the intake duct and/or the intake region of the baling chamber. A correlation function is determined by correlating the measured relative density of slices in the intake duct and/or the intake region of the baling chamber with the cumulative weight of these slices after they have been compressed and bound to form a completed bale. The control system predicts a weight of the slice in the intake duct and/or the intake region of the baling chamber derived from the measured relative density values of this slice and the computed correlation function.

Abstract: The present invention relates to a method for improving the operation of a grain cleaning system in a combine harvester characterized in that the method comprises the step of adjusting the position of the upper sieve in the grain cleaning system upon registering a deviance from a threshold value for crop material load on the upper sieve such that the material return flow is adjusted. The present invention further relates to a sieve overload control algorithm capable of activating an optimal sieve control action upon registration of a deviance from a threshold value for crop material load on the upper sieve of a grain cleaning system.
