An agricultural spraying machine having a defined transport width includes a chassis supported on the ground and configured to be set into motion in a forward direction, and a sprayer boom mounted on the chassis. A controller operably controls an actuator influencing the propulsion speed or driving direction of the chassis or the sprayer boom for reducing an oscillation of the sprayer boom in the forward direction. The controller triggers the actuator in response to a detected or expected oscillation of the boom due to a resulting change of speed or travel direction of the chassis or sprayer boom. An oscillation in an opposite phase to the detected or expected oscillation of the sprayer boom is induced in the sprayer boom adapted to lead to the reduction or cancellation of the oscillation of the sprayer boom.
