Header

The invention relates to an agricultural harvester (1) comprising a header (2) having a pickup mechanism (110) for picking up crop from a field and a feeder for feeding the crop into the agricultural harvester (1) for further processing. The feeder is pivotally connected to the chassis of the agricultural harvester (1) via at least one lift cylinder (600). The header (2) is connected to the feeder for pivoting with the feeder and comprises a pick-up mechanism supported by a frame (100). The header (2) further comprises at least one wheel (165A, 165B) for supporting the frame (100) on the ground. A sensor (50) is configured for detecting a surface composition of an area behind the pick-up mechanism (110), and a control system (500) is operably coupled to the at least one lift cylinder (600) and the sensor (50) and is configured for operating the at least one lift cylinder (600) to adjust a pressure applied by the header (2) to the ground in accordance with the detected surface composition. 本发明涉及一种农业收割机(1)，其包括收
