A crop processor for cracking kernels in a forage harvester, the crop processor including: a housing having an inlet and an outlet; and a first and a second comminuting roll mounted inside the housing, the comminuting rolls being arranged in parallel to define an opening between the rolls, the comminuting rolls being configured to rotate, during use, in opposing rotation directions to transport a flow of harvested crop, received from the inlet, through the opening towards the outlet, wherein the first comminuting roll is configured to rotate at a greater speed than the second comminuting roll; wherein the first and second comminuting rolls each include a plurality of teeth arranged on a circumferential surface of the comminuting roll, each of the plurality of teeth includes a leading edge which faces in the rotation direction of that comminuting roll.

The invention relates to a shear bar (20), in particular for a forage harvester or another agricultural or silvicultural machine, having a carrier (21) that comprises a cutting region (30); a plurality of cutting elements (31) being set alongside one another in the cutting region (30); the cutting elements (31) comprising a partial edge and at least some of the partial edges forming a cutting edge (32) that is embodied to form, with a knife bar, a cutting engagement for the material to be shredded; the cutting edge (32) forming a transition between a cutting surface (32.1) that is constituted by the cutting elements (31) and extends transversely to the cutting direction, and an exposed surface (32.2) that extends substantially in a cutting direction and indirectly or directly adjoins the cutting edge (32). A shear bar of this kind can be configured to be break-resistant with little complexity in terms of parts and manufacture if provision is made that an infeed element (34), which is embodied as a sintered part made of hard material having an infeed bevel (34.6) profiled on in the sintering process, is provided on or in the row of cutting elements (31); the infeed bevel (34.6) being carried over indirectly or directly into the cutting edge (32); and the infeed bevel (34.6) being arranged at a tilt with respect to the cutting edge (32) in such a way that it is arranged with a setback with respect to the exposed surface (32.2) and toward the cutting surface (32.1).

An arrangement for data recording and sampling for an agricultural machine includes a sensor set-up arrangement to detect properties contained in a material stream, means of taking a sample of the material from the material stream, and an electronic control unit. The control unit is configured to perform the following steps in response to a tripping signal: (a) instruct an actuator to bring the means into a position for sampling; (b) starting a recording of raw sensor arrangement data in a memory; (c) after depositing the sample at a desired sampling location, stop recording the raw data and instruct the actuator to return the means from the sampling position to an inactive position; and (d) store identification data to identify the sample together with the raw data in memory.

An image capture device captures an image of crop after it has been processed by a kernel processing unit on a forage harvester. A size distribution indicative of the distribution of kernel fragment sizes in the harvested crop is identified from the image captured by the image capture device. A control system generates control signals to control a speed differential in the speed of rotation of kernel processing rollers based on the size distribution. Control signals can also be generated to control a size of a gap between the kernel processing rollers.

A detection arrangement for detecting a wear status of a chopping knife arrangement of a chopping device provided for processing a product flow, wherein the chopping device has a revolving chopping drum receiving the chopping knife arrangement and at least one shear bar which cooperates with the chopping knives, with a sensor arrangement which has a magnetic exciter arrangement and a flux conducting device magnetically coupled thereto. The sensor arrangement provides a pole arrangement which forms at least one magnetic pole with a pole surface for conducting magnetic flux, wherein at least a portion of the chopping knife passes the pole arrangement during a rotation of the chopping drum. A voltage induced when a chopping knife arrangement passes the sensor arrangement forms the measured magnetic value, which is used by the evaluation unit to determine the state of wear of the chopping knife arrangement.

An agricultural harvester includes one or more actuators configured to move a crop unloading tube of the harvester relative to a frame of the harvester. Additionally, the agricultural harvester includes a sensor configured to capture data indicative of a presence of the crop receiving vehicle within a crop unloading zone of the agricultural harvester. Moreover, the agricultural harvester includes a computing system communicatively coupled to the sensor. As such, the computing system configured to determine when the crop receiving vehicle is present within the crop unloading zone based on the data captured by the sensor. In addition, when it is determined that the crop receiving vehicle is present within crop unloading zone, the computing system is configured to control an operation of the one or more actuators such that the crop unloading tube is moved relative to the frame from a current position to a predetermined crop unloading position.

Method for operating an agricultural harvester (1), wherein the agricultural harvester (1) has an attachment (2), wherein the attachment (2) has a receiving conveyor (7) which is driven at a defined first speed, wherein the attachment (2) has a discharge conveyor (8) which is driven at a defined second speed, wherein the harvester (1) has an infeed unit (4) with infeed rollers (5, 6) which are driven at a defined third speed. The second speed, at which the discharge conveyor (8) is driven, is determined depending on the third speed, at which the infeed rollers (5, 6) are driven, and also depending on the speed of travel of the agricultural harvester (1).

Stalk conditioners for conditioning stalk stubble present in a field after harvesting of a crop are disclosed. In some instances, the stalk conditioners may include a bracket configured to be secured to a piece of agricultural equipment, such as an implement; an arm pivotably coupled to the bracket; and a blade that is disposed in a slot formed in the arm. The blade may be rotatable relative to the arm. The blade and arm may be configured to engage stalks stubble within a field following harvesting of crops, including during the course of a harvesting operation, to break and cut the stalks so as to promote decomposition of the stalk stubble.
