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.
