The electric motor/generator is able to be operated as a generator for braking the conditioning roller and to return the generated electrical energy into a drive system of the forage harvester.

Corn header (4) for a forage harvester (1) for harvesting stalk crops, having a plurality of mowing and infeed units (5), which each have a plurality of drum-like or chain-like mowing and infeed members (6), which are rotatable about a vertical axis and are drivable in a revolving manner, for severing the crop in a substantially horizontal direction from a field to be cultivated, wherein the mowing and infeed members (6) of a pair (11) of mowing and infeed units (5) arranged in the center between two sides (4a, 4b) of the corn header (4) are drivable in a revolving manner such that they have a tendency to convey crop out of a gap (12), which is formed between them, forwards away from an infeed (9) of the forage harvester (1), wherein a central separating member (13) for separating the crop is positioned in a substantially vertical direction in the region of the gap (12) between the mowing and infeed members (6) of the pair (11) of mowing and infeed units (5) arranged in the center of the corn header (4).

A mobile agricultural machine includes a header configured to engage crop at a worksite and a controllable header actuator configured to drive movement of the header relative to a surface of the worksite. The mobile agricultural machine further includes a crop constituent sensor system configured to sense the crop and generate a crop constituent sensor signal indicative of a value of a constituent of the crop. The mobile agricultural machine further includes a control system configured to generate a control signal to control the mobile agricultural machine based on the detected value of the constituent of the crop.

A chopper assembly having a discharge conduit. A first and a second beater disposed within the discharge conduit and a first door and a second door in the bottom wall of the discharge conduit positioned below the first beater and the second beater respectively.

A wear plate assembly for an agricultural harvester including a support element having a number of lateral regions, each lateral region being provided with a plurality of first engagement features, one or more replaceable wear plates provided on one side with a plurality of second engagement features for engagement with the first engagement features, and a plurality of fastenings to secure each replaceable wear plate to the support through the engagement features.

A method and system for identifying lengths of a particle in a flow of harvested material comprising particles in an agricultural harvester is disclosed. The agricultural harvester has at least one work assembly for harvesting a crop or for processing harvested material of the crop and can be adjusted using machine parameters. The harvested material is transported as a flow of harvested material through the agricultural harvester while the agricultural harvester is operating. The agricultural harvester has a camera that takes images of the flow of harvested material, with a computing unit of the agricultural harvester analyzing the images of the flow of harvested material in an analytical routine thereby finding particle lengths of particles of the flow of harvested material that are an excess length. The analytical routine is based on a machine learning method trained to find particles with the excess length, with the computing unit using the analytical routine to ascertain an amount of particles with the excess length.

A forage harvester is disclosed. The forage harvester has at least one work assembly for processing harvested material of a crop, which includes grain components. In operation, the harvested material is transported in a harvested material flow along a harvested material transport path through the forage harvester. The forage harvester further includes a corn cracker as a work assembly and a control assembly that includes an optical measuring system. The optical measuring system has a camera for recording image data of the harvested material, with the camera being positioned after the corn cracker. The control assembly, using an image recognition routine, determines image regions assigned to a comminuted grain component in the image data, determines geometric properties of the assigned comminuted grain components based on the image regions, and determines an indicator of a processing quality of the comminuted grain components from the geometric properties.

Crop processing rolls for operative use in forage harvesters are formed from independent segments having a plurality of first grooves that are oriented in a parallel manner with second smaller grooves intersecting the ridges to form discrete teeth from the ridges. The ridges can be formed vertically, horizontally or in a spiraled pattern with the smaller second grooves oriented into a spiraled pattern to form the discrete teeth. Crop processing roll segments can be formed in this manner and assembled into full processing rolls with the spiraled second grooves being oriented in opposing directions from adjacent segments. The number of segments can vary from two to eight individual segments with the second grooves breaking ridges into discrete teeth on adjacent segments forming a chevron pattern at intersecting positions along the longitudinal length of the processing roll.
