A device used to spread liquids, such as fertilizers or the like, having - at least two cantilever arms , each with a plurality of means used to distribute the liquid, which at least two cantilever arms are pivotable about one or more axes running approximately parallel to a driving direction of the device; - one or more actuators , which are connected to the at least two cantilever arms , and which can transmit an actuating force for a pivoting movement onto the at least two cantilever arms ; - one or more first sensors by means of which a relative actual spacing of the at least two cantilever arms to a ground-side crop to be treated and/or a relative tilt position of the at least two cantilever arms in relation to a horizontal can be determined; and - one or more second sensors , by means of which an environmental profile, at least preceding in driving direction of the device , can be detected; wherein the one or more first sensors and the one or more second sensors are connected to a control apparatus (S), by means of which the one or more actuators are controllable for a defined pivoting movement of the at least two cantilever arms in consideration of the actual spacing and/or of the relative tilt position determined by the one or more first sensors and in consideration of the environmental profile detected by the one or more second sensors ; and - one or more scanners, by means of which a surrounding, at least preceding the device in driving direction, is scannable across the entire working width and a surface model is generatable based on the detected data, characterised in that the one or more scanners are connected to the control apparatus (S) by means of which the at least two cantilever arms are presettable based on the surface model, and a control signal from the one or more first sensors is overridable, if required. - at least two cantilever arms , each with a plurality of means used to distribute the liquid, which at least two cantilever arms are pivotable about one or more axes running approximately parallel to a driving direction of the device; - one or more actuators , which are connected to the at least two cantilever arms , and which can transmit an actuating force for a pivoting movement onto the at least two cantilever arms ; - one or more first sensors by means of which a relative actual spacing of the at least two cantilever arms to a ground-side crop to be treated and/or a relative tilt position of the at least two cantilever arms in relation to a horizontal can be determined; and - one or more second sensors , by means of which an environmental profile, at least preceding in driving direction of the device , can be detected; wherein the one or more first sensors and the one or more second sensors are connected to a control apparatus (S), by means of which the one or more actuators are controllable for a defined pivoting movement of the at least two cantilever arms in consideration of the actual spacing and/or of the relative tilt position determined by the one or more first sensors and in consideration of the environmental profile detected by the one or more second sensors ; and - one or more scanners, by means of which a surrounding, at least preceding the device in driving direction, is scannable across the entire working width and a surface model is generatable based on the detected data, characterised in that the one or more scanners are connected to the control apparatus (S) by means of which the at least two cantilever arms are presettable based on the surface model, and a control signal from the one or more first sensors is overridable, if required. <EOS>
