A harvest header for a harvesting machine includes a carrying frame, a mechanism for receiving or cutting harvest material from a field, a control device, a power-operated actuator operably controlled by the control device, and a transverse conveyor screw movably controlled between two or more positions. The position of the transverse conveyor screw is adjustably controlled by the actuator in order to transport the harvest material to a discharge opening. The control device independently controls the actuator based on at least one harvest material property.

A combine harvester includes a load-bearing undercarriage movable via a drivable device engaged in the ground, a threshing and separating device attached to the load-bearing undercarriage, and a feeder house attached to the load-bearing undercarriage. The feeder house includes an endless traction mechanism which circulates about a vertically movable lower deflection roller and a drivable upper deflection roller. A harvesting attachment is coupled to the feeder house for receiving or cutting off harvested crops which are lying or standing upright on a field and which are able to be supplied via the feeder house to the threshing and separating device. An actuator is actuated by an external force arranged for adjusting the vertical position of the lower deflection roller and is connected to a control device which is coupled to a sensor for determining a throughput by a transmission of a signal.

A cutter head for a harvester, with a cutterbar for cutting crop from a field, a reel with reel fingers which is disposed above the cutterbar, and a cross conveyor for transporting the cut crop to a rear discharge opening. The reel includes reel arms that can be driven about a rotating axis, reel finger carriers supported on the reel arms so they can rotate about the lengthwise axes of the arms, with reel fingers mounted thereon, and an externally powered actuator connected to an electronic control unit for adjusting the rotary angle of the reel finger carrier relative to the reel arms.

Cutter head with automatic setting of the reel finger orientation

A chopping blade for a straw chopper comprises a fastening opening, two side faces, and cutting edges arranged on one or both ends of the side faces. At least one of the side faces is equipped with means for reducing the frictional resistance of the chopping blade relative to the air and/or the chopping material.

A system for controlling an operative parameter of a harvesting platform of an agricultural harvesting machine comprises a sensor adapted to provide downed crop information indicative of a characteristic of downed crop in a field to be harvested and an electronic control unit adapted to control an operative parameter of at least one of a reel and a cutter bar table position of the harvesting platform based upon the downed crop information.

System for optimizing platform settings based on crop state classification

A drive arrangement for the reciprocating drive of a cutter bar comprises an input element which can be set into a continuous pivoting movement by a drive device, and an output element which is coupled to the cutter bar and is coupled to the input element by a coupling rod. The output element is pivotably connected to a first end of a first lever and of a second lever, which levers, for their part, are pivotably mounted. The levers and the output element are dimensioned in such a manner that the output element essentially only carries out a lateral movement.

In a crop residue chopping and distributing arrangement for a combine harvester () with a straw chopper () and two discharge blowers (), a guide element () distributes the crop residue stream over the two discharge blowers () is arranged between said blowers. Passages () remain between the guide element () and the discharge blowers () such that the crop residues can be rearwardly discharged onto the field by the straw chopper () through said passages. Outer guide elements () are provided between the straw chopper () and the discharge blowers () in order to deflect the outer regions of the crop residue stream inward. The straw chopper housing () may feature a curved bottom () that axially conveys the crop residues to the discharge blowers () at an angle, wherein a flat crop residue guide element () is arranged between the straw chopper housing () and the discharge blowers ().

A crop residue chopping and spreading arrangement is described with a straw chopper () and an impeller blower () arranged downstream of the straw chopper (). The impeller blower comprises impeller paddles () that can be set in rotation about a rotational axis () and an end-side cover () arranged directly adjacent to the impeller paddles (). The impeller paddles () receive crop residue in a take-up region from the straw chopper () and discharge it in a discharge region onto a field. The end-side cover () is provided in front of the discharge region, with respect to the direction of rotation of the impeller paddles (), with an opening () through which, during operation, the impeller paddles () take in air and discharge it in the discharge region, wherein this arrangement increases the throwing range of the impeller blower ().
