An agricultural header includes a main section and at least one wing section, which is pivotably coupled to the main section. The main section includes a main frame. The at least one wing section includes a wing frame. The header further includes a cutting element, a linkage, and an actuator. The cutting element is supported by the main frame and the wing section. The linkage pivotably couples the at least one wing section to the main section. The linkage includes an upper bar and a lower bar which are both coupled to the main frame and to the wing frame. The actuator is coupled to at least one of the upper bar, the lower bar, and the at least one wing section.

Described herein are methods and harvesters for adjusting settings of a harvester. In one embodiment, a computer Implemented method includes capturing, with at least one image capture device that is located on the harvester, images of a field view of an unharvested region to be harvested, analyzing the captured images to determine crop information for a crop of a harvested region that is adjacent to the unharvested region, and adjusting settings or operating parameters of the harvester for the unharvested region based on the crop information for the crop of the harvested region.

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.

An agricultural vehicle includes a feederhouse having a first output shaft that is configured to be connected to a header, and a second output shaft that is also configured to be connected to the header. The first and second output shafts are configured to be operated at different rotational speeds on the feederhouse for driving different header drives on the header at different speeds.

A universal crop head assembly is carried at the front of and by a harvester. The new crop head assembly includes a frame assembly, an intermediate multi-crop reel assembly carried by the frame assembly and having selectively extendable and retractable fingers for small grain harvesting. A lower cutter bar assembly is carried by the frame assembly and for cutting grain stalks. An upper forward cutter bar assembly is carried by the frame assembly and supports an upper cutter bar for cutting corn stalks about an upper end, an adjustable air knife assembly for blowing against severed corn stalks upper ends; and a lower draper belt assembly carried by the frame assembly and for moving grain cut by the lower cutter bar assembly.

A crop detection system and method of using the same includes a machine vision system mounted to a mobile vehicle. The machine vision system includes an information capturing device connected to a computer having a processor and memory. The memory includes stored crop and field information. Positioning members are mounted to an extend forward of the mobile structure. The information capturing device includes a camera, a sensor, a transceiver and/or a stereo sensor configuration and is positioned to sense the presence, size, location and orientation of characteristics of a crop.

A row unit assembly for use with a corn harvester includes a first drive having an output shaft, a stalk roll that extends along a first axis and rotates about the first axis via the output shaft of the first drive. A second drive rotates a first drive member about a second axis that is substantially perpendicular to the first axis. A first conveyor extends around the first drive member and moves about the first drive member in response to rotation of the first drive member. A third drive rotates a second drive member about a third axis that is substantially parallel to the second axis. A second conveyor extends around the second drive member and moves about the second drive member in response to rotation of the second drive member.
