Abstract: The invention relates to a method for regulating the throwing behavior of a centrifugal spreader for fertilizer and to a centrifugal spreader configured therefor. According thereto, a target throwing distance is determined for a target working width. Furthermore, one of several rotational speed levels is selected for at least one spreading disc to approximate the actual throwing distance to the target throwing distance. Finally, an adapted target throwing angle for regulating an actual throwing angle is determined from the actual throwing distance (WW1) and counteracts in a compensatory manner a deviation from the target working width caused be the difference between the actual throwing distance and the target throwing distance. Continuous regulation of the throwing distance then becomes unnecessary, resulting in more stable regulation of the overall throwing behavior.
