A device for spreading liquid and/or solid active agents comprises a carrier vehicle, at least one pivotable boom, and sensors for detecting an angular velocity and/or an angular position of the boom. A control unit processes output signals of the sensors to control signals for an actuator to adjust the boom. The actuator produces an actuating connection between the carrier vehicle and the pivotable boom, and has one active pressure side, which is engageable by fluidic actuating pressure, for each of the two adjustment directions of the boom. An approximately equal pressure prevails on the active pressure sides of two actuators operating in opposition or of a double-acting actuator, respectively, when the boom is stationary or moves only slightly in relation to the carrier vehicle. A defined differential pressure is adjustable between the active pressure sides of the two actuators or of a double-acting actuator, when the boom is shifted.
