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.

Repaired combine augers are provided that can include: a central cylindrical object configured to support flighting extending about the central cylindrical object, wherein at least one portion of the flighting is damaged and defines non-linear portions, openings, and/or bent sections; and at least one semi-circular repair component bound to the portion to align with remainder of the flighting.

A bubble-up auger for a combine harvester includes a rotatable shaft, a lower auger section either mounted to or forming part of the rotatable shaft, and an upper auger section that is removably connected to the lower auger section, and includes an opening through which the shaft is at least partially positioned. The upper auger section is moveable between a first position where the upper auger section is detached from the lower auger section and a second position where the upper auger section is connected to the lower auger section.

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.

A method for automatically controlling a harvesting parameter on a header of a combine harvester. The combine harvester includes the header, a feeder, and a downstream processing device. Crop is cut by the header, transferred to the feeder, and then transported to the processing device. The method includes steps of detecting at least one crop property in the feeder by at least one sensor and outputting at least one corresponding crop property signal; receiving the at least one crop property signal by a control unit; processing the at least one crop property signal in the control unit; transmitting at least one control signal by the control unit to at least one actuator on the header; and executing the at least one control signal in the at least one actuator so as to automatically control the harvesting parameter on the header

An agricultural header comprises a first side draper belt, a second side draper belt, a first center draper belt, a second center draper belt, and a crop divider. The first and second center draper belts are positioned laterally between the first and second side draper belts which extend laterally outwardly in opposite directions away from the first and second center draper belts. Each of the first and second side draper belts are arranged to feed crop material laterally inwardly, and each of the first and second center draper belts are arranged to feed crop material rearwardly for processing by the agricultural harvester. The crop divider is positioned laterally between the first and second center draper belts to separate crop material fed laterally inwardly from the first and second side draper belts respectively to the first and second center draper belts.

A mower has a plurality of rotary cutters for cutting a crop and a swathing unit for forming a cut crop into a swath. In some embodiments, the swathing unit includes an auger and a housing that extends around at least part of the auger and provides a swathing aperture through which cut crop material is ejected to form a swath. In some embodiments, the housing includes at least one guide plate that can be adjusted to adjust the width W of the swathing aperture.

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.
