Disclosed is a device for spreading liquid and/or solid active agents as well as a method for controlling the device. The device comprises a carrier vehicle, at least one boom arranged pivotably about a rotation axis, and at least one sensor arrangement for detecting an angular velocity and/or an angular position of the boom about the rotation axis in relation to a reference plane. A control unit processes output signals of the sensor arrangements to control signals for an actuator for the purpose of pivoting the boom. Two actuators or a double acting actuator provide an actuating connection between the carrier vehicle and the pivotable boom, wherein the actuator has one active actuating side for each of the two pivoting directions of the boom, which active actuating side is electromagnetically or electromotively actuatable.
