An agricultural harvester includes a header with a pickup mechanism for picking up crop from a field and a feeder for feeding the crop into the agricultural harvester for further processing. The feeder is pivotably connected to a chassis of the agricultural harvester via at least one lift cylinder. The header is connected to the feeder for pivoting therewith and includes a pickup mechanism supported by a frame. The header further includes at least one wheel for supporting the frame on the ground. A sensor is configured to detect a ground surface composition in an area behind the pickup mechanism, while a control system is operably coupled to the at least one lift cylinder and the sensor, and configured to operate the at least one lift cylinder to adjust a pressure that the header exerts on the ground in dependence of the detected ground surface composition.

A cutter device for an agricultural harvester comprises a rotor with a plurality of tines, a knife that is adjustable between a cutting position and a non-cutting position, and a positioning device that controls movement of the knife. The positioning device is adjustable between (i) a first position in which it positions the knife in the cutting position, (ii) a second position in which it positions the knife in the non-cutting position, and (iii) a third position in which it is disengaged from the knife to allow movement of the knife independently of the positioning device. The positioning device is configured to engage the knife and prevent significant movement of the knife independently of the positioning device when the positioning device is in the first position and at intermediate positions between the first position and the second position.
