Abstract: An agricultural harvester including a sensor for measuring a position of an object in surroundings of the harvester. The sensor is connected to a processor for defining at least two different danger zones respectively corresponding to at least two different sets of harvester driving parameter values. The processor can determine actual harvester driving parameter values, and the processor can compare the actual harvester driving parameter values with the different sets to select a matching set and to select a corresponding one of the danger zones. The processor outputs a warning signal if the position is in the corresponding danger zone.

Abstract: A controller for a harvester. The controller is configured to receive crop flow information representative of how crop is flowing through the harvester and generate display information for providing a visual display to an operator of the harvester. The visual display includes an animation of crop flowing through the harvester. The controller is further configured to set one or more properties of the animation of the crop flowing through the harvester based on the received crop flow information.

Abstract: A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.
