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.

A residue spreader for receiving crop residue from a residue chopper of a combine harvester and for spreading crop residue onto the ground. The spreader includes a spreader body having an inlet and an outlet side, and left and right groups of deflectors, each deflector pivotally mounted on the spreader body in juxtaposed position and configured to laterally deflect the crop residue between the inlet side and the outlet side. The deflectors within each group are coupled together for pivoting movement in unison. A distribution actuator has an actuator body and an actuator element and the actuator body is mounted to the spreader body. The actuator element is coupled to both the left and right groups of deflectors by respective pivoting links. The actuator body is adjustably mounted to the spreader body. An adjustment actuator is connected to the actuator body to control movement of the actuator body with respect to the spreader body to adjust a spread width.

The reel assembly further includes a device mounting assembly coupled to the reel arm and configured to support a device that is configured to monitor a terrain feature. The device mounting assembly is configured to maintain an orientation between the device and a ground on which the agricultural header is positioned as the reel arm rotates relative to the frame of the agricultural header.

A combine includes: a reaper to reap planted grain culms in a field; a threshing apparatus to thresh the reaped grain culms and separate the reaped grain culms into separated material containing normal grain and material to be discharged other than the separated material; a grain tank in which the separated material is storable; a conveying apparatus to convey the separated material from a separation section to the grain tank; a temporary storage section to take out and store some of the separated material that is being conveyed by the conveying apparatus; an image capture unit to capture an image of the separated material stored in the temporary storage section; and an image analysis module to analyze the image captured by the image capture unit, and perform distinguishing processing for distinguishing the normal grain in the separated material stored in the temporary storage section from foreign matter.

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.
