Abstract: A crop tank system has a crop tank for receiving harvested crop and a fill level sensor arrangement for detecting fill level information regarding the crop tank. The fill level sensor arrangement includes a radar sensor, which sends out and receives radar rays that, depending on the fill level of the crop contained in the crop tank, penetrate the crop contained in the crop tank and/or are reflected by the crop contained in the crop tank. The fill level sensor arrangement also includes an electronic sensor control, which determines the fill level information based on the received radar rays.

Abstract: A self-propelled agricultural working machine has at least one working unit such as a ground drive, a driver assistance system for generating control actions within the working machine, and a sensor system for generating pieces of environmental information. The driver assistance system generates the control actions on the basis of the pieces of environmental information. The driver assistance system assigns an urgency level to each of the pieces of environmental information and generates the control actions on the basis of the pieces of environmental information and the particular assigned urgency levels.

Abstract: An agricultural machine with an implement for working a row culture of working rows arranged parallel to one another, interference rows arranged at an angle to the working rows or both includes at least one controllably moveably working section with activatable working devices for working the row culture. The implement has a control unit for controlling the working section and working device relative to a working row and an optical sensor unit connected to the control unit for generating an image of at least part of the row culture, from which a sensor signal (S) is generated for controlling the controllably working section, working device or both. The control unit evaluates a validity of the sensor signal (S) to determine whether the sensor signal (S) is used for controlling the working section or working device based on at least one evaluation parameter.
