The invention is directed to a agricultural machine for conducting an agricultural working process with at least one working organ (2-6) and with a driver assistance system (7) for the control of the at least one working organ (2-6), wherein a sensor arrangement (8) is assigned to the driver assistance system (7), which sensor arrangement (8) comprises at least one radar sensor (9, 10). It is proposed that the sensor arrangement (8) comprises at least one ground penetrating radar sensor (9-12), which within a running agricultural working process obtains a ground information (D) in a detection area (13, 14) below the surface (15) of the ground (G) and that the driver assistance system (7) data-processes the obtained ground information (D) for the running agricultural working process and/or for subsequent working processes.
