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.

Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) and a rear grain cart, wherein the PPU carries dual axially mounted engines with oppositely opposed crankshafts with one toward the rear grain cart and the other engine away from the rear grain cart, there being no comingling of flywheel output power flow between the two engines.

A sugarcane harvester includes a basecutter assembly for cutting sugarcane stalks from sugarcane plants; a chopping section for receiving the sugarcane stalks from the intake and cutting assembly and chopping the sugarcane stalks into billets; a discharge assembly for receiving the billets from the chopping section and discharging the billets to a storage vehicle; and a height adjustment system for automatically adjusting a height of the basecutter to avoid unwanted contact between the basecutter and a ground surface.

Compound headers may include two or more crop harvester types that are operable to harvest different crops simultaneously, such as different crops grown in the same field in an intercropped relationship. The simultaneously harvested crops may be separated into individual crop flows that are handled separately from each other.

An arrangement for controlling the operation of a draper belt header of a combine harvester includes a central belt conveyor of the draper belt header having a drive for operably driving the conveyor and two outer belt conveyors attached to a feeder house of the combine harvester. The feeder house has a controllable height which may be controllably adjusted by an actuator. The arrangement further includes a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator.

Methods and apparatus to identify headlands are disclosed. A disclosed example apparatus to identify a headland of a field includes an image analyzer to generate an image from data corresponding to path information of at least one field operation performed on the field, a mask generator to generate a mask of the image based on the image, and a headland identifier to identify the headland in the field based on the mask.

A method for electrification of a field chopper comprising the steps of: providing a cable drum and a winding drive on the field chopper, the cable drum and winding drive allowing at least one of the winding and unwinding of an energy supply line about the cable drum; providing a cable arm on the field chopper, the cable arm configured to adjust in at least one of an orientation and extension length to provide guided winding or unwinding of the energy supply line along a field surface; providing a pivotable ejection chute on the field chopper, the ejection chute extending beyond the cable arm and configured to transfer a chopped harvested material onto a transport vehicle driving alongside the field chopper; unwinding the energy supply line while along a first processing strip from the cable drum using the winding drive and cable arm; and winding the energy supply while along a second processing strip about the cable drum using the winding drive and the cable.

A screening device and a self-propelled harvester with a screening device is disclosed. The screening device includes at least one suction nozzle that has an elongated hollow body with at least one suction opening which extends sectionally in the longitudinal direction and transverse direction of the hollow body, and is connected by at least one air duct in the interior of the hollow body to a connection arranged in the hollow body for connecting to a vacuum source. The suction opening is positioned facing a screen of the screening device. The air duct has a cross-sectional shape that increases in the vertical direction toward the connection starting from an outer end of the suction nozzle. An inner contour facing the suction opening of the air duct has a contour that substantially corresponds to an airfoil.
