An agricultural harvester includes an annular housing having an arcuate cross-section such that the annular housing defines a toroidal chamber therein.

Furthermore, the agricultural harvester includes a blade supported below the annular housing in a vertical direction, with the blade configured to sever top portions of plants from stalks of the plants. Additionally, the agricultural harvester includes a crop flow director positioned above the blade in the vertical direction, with the crop flow director configured to direct the severed top portions into the toroidal chamber. Moreover, the agricultural harvester includes an elevator assembly supported relative to the annular housing. In addition, the agricultural harvester includes a fan assembly configured to generate a flow of air through the annular housing to convey the severed top portions from the toroidal chamber to the elevator assembly.

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.

Disclosed is a lifting assembly for a crop severing assembly forwardly carried by a tractor having a frame and front a frame and an axle assembly carrying front wheel assemblies. The crop severing assembly has a forward end and a rear end, and includes a pair of bracket assemblies located at the forward end and atop the crop severing assembly. A pair of lift cylinder assemblies each have a lower end and a top end. The lift cylinder lower ends are located at either side of the rear end of the crop severing assembly to bottom brackets extending from the tractor frame forward of the tractor axle assembly and are attached between each cylinder lower end and each cylinder top end to trunnions carried by the crop severing bracket assemblies for pivotally raising and lowering of the forward end of the crop severing assembly.

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.

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

A weeding machine and a weeding method for seedlings in a paddy field are disclosed. The weeding machine includes a paddy field power chassis, a lifting hydraulic cylinder, a parallelogram suspension frame, a weeding frame, a transmission assembly, and weeding units. The paddy field power chassis vertically adjusts the working depth of the weeding machine through the parallelogram suspension frame and the lifting hydraulic cylinder. The power is transmitted to the weeding units by the transmission assembly. The weeding units are used for pulling out weeds between rows and feeding the weeds to weed chopping channels. Spiral weed chopping knives are used for chopping the weeds and conveying the weeds to feeding channels. Bidirectional variable-pitch augers are used for conveying the chopped weeds to discharge openings of the feeding channels under pressure and discharging the chopped weeds for burying weeds between plants.

A reel assembly for an agricultural header including a reel arm configured to rotatably couple to a frame of the agricultural header and configured to support a reel of the reel assembly. 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 reel power system for a header of an agricultural system includes an electrical generator having a stator and a rotor rotatably engaged with the stator. The stator is configured to be non-rotatably coupled to a support structure of a reel of the header. The rotor is configured to non-rotatably engage a base of the header. Furthermore, the reel is configured to rotate relative to the base. The electrical generator is configured to generate electrical power in response to rotation of the rotor.
