A combine harvester includes a feederhouse mounted to a chassis adapted at a front end to support a crop gathering header, a duct mounted on the feederhouse that is connected to a crop conveying passage of the feederhouse via a set of suction openings, a set of vent openings in the duct, each of the vent openings having a respective closure element movable between an open position and a closed position, and a fan arranged within the duct that can be operated in a first direction to create a suction airflow to extract dust from the crop conveying passage and discharge the dust through the duct, and in a second direction to create a blowing airflow to open the closure elements and vent air through the vent openings.

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.

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

Method for operating an agricultural harvester (1), wherein the agricultural harvester (1) has an attachment (2), wherein the attachment (2) has a receiving conveyor (7) which is driven at a defined first speed, wherein the attachment (2) has a discharge conveyor (8) which is driven at a defined second speed, wherein the harvester (1) has an infeed unit (4) with infeed rollers (5, 6) which are driven at a defined third speed. The second speed, at which the discharge conveyor (8) is driven, is determined depending on the third speed, at which the infeed rollers (5, 6) are driven, and also depending on the speed of travel of the agricultural harvester (1).

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 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.

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.

Crop is carried into a feed opening of a harvester by two side drapers, two rear back sheets defining an opening between inner edges, a central feed draper and a roller with end flight portions and a central finger portion located above the feed draper. In this geometry, a bottom tangent to the flight portions has a position which is at a height below the rear edge of the side drapers. The roller axis of the feed roller is behind the rear edge of the side drapers and behind a common plane containing the back sheets. The inner guide roller of each of the first and second side drapers is located inwardly of the inner edge of the first back sheet and inwardly of an outer end of the end flight portion. A forward most tangent to the flight portions projects forward of or proud of the common back sheet plane.

A feeder for an agricultural vehicle includes a feeder body defining a hollow interior space for receiving crop material from a header of the agricultural vehicle, a faceplate that is movably mounted to the feeder body, and a scissor jack assembly that is configured for rotating the faceplate with respect to the feeder body to adjust a fore-aft angle of the faceplate relative to the feeder body. The faceplate is configured to be removably coupled to the header of the agricultural vehicle.

A system and method for reversing a movement direction of a laterally extending conveyor of a draper header of an agricultural machine. The system includes a fluid line for delivering fluid to a motor that drives the laterally extending conveyor. A directional flow control valve is connected to the fluid line and is movable between a first state in which the directional flow control valve is configured to deliver the fluid to the motor in a first fluid direction to cause the motor to move the laterally extending conveyor in a first movement direction, and a second state in which the directional flow control valve is configured to deliver the fluid to the motor in a second fluid direction that is different from the first fluid direction to cause the motor to move the laterally extending conveyor in a second movement direction that is opposite to the first movement direction.
