Self-propelled harvester having a height-adjustable pick-up device

A self-propelled harvester comprising:

• a height-adjustable pick-up device configured to connect to a draper that is configured to pick up harvested material, the height-adjustable pick-up device comprising a virtual pendulum axis on which the draper is pivotable, the height-adjustable pick-up device configured for adaptive adjustment of a vertical distance of the draper from ground, the height-adjustable pick-up device including at least one actuator configured for transverse guidance of the draper, wherein the draper includes a central section and at least two side sections which are each connected to the central section by a frame joint so as to be pivotable about a pivot axis running parallel to a longitudinal axis of the harvester;
• and
• a hydraulic system comprising a pressure source, a hydraulic circuit, and at least one hydraulic cylinder connected to the hydraulic circuit, wherein the hydraulic cylinder is configured to move at least one support wheel with respect to height, the at least one support wheel positioned on the draper;
• wherein the harvester is configured to regulate position of the draper in a transverse direction by pivoting about the virtual pendulum axis independently of the at least one actuator configured for transverse guidance of the draper;
• wherein the hydraulic system comprises at least one actuator configured to pivot at least one of the at least two side sections relative to the central section about the pivot axis transverse to a direction of travel of the harvester;
• wherein the draper comprises one or more supporting arms that are configured to pivot about an axis running in the transverse direction and are positioned on the central section and the at least two side sections;
• wherein the one or more supporting arms carry a cutter bar;
• wherein a plurality of sensor apparatuses are configured to detect a vertical deflection of the one or more supporting arms of the central section and the at least two side sections;
• and
• wherein each of the plurality of sensor apparatuses comprise a measuring shaft connected in a rotationally fixed manner to the one or more supporting arms of the central section.
