Abstract
A self-propelled ground milling machine includes a working roller, a hold-down device which is height-adjustable with respect to the traffic surface being arranged upstream of the working roller in the working direction, and a detection unit which determines a physical variable characteristic of an undesirable state of the operating process, wherein fragments are broken off from the traffic surface, apply compressive force to the hold-down device and can press the hold-down device into a raised position with respect to the traffic surface. A device for height-adjusting the hold-down device responds by applying a contact pressure, directed counter to the compressive force applied by the fragments, to the hold-down device. By applying sufficient contact pressure, the hold-down device can be effectively prevented from rising from the traffic surface, such that during the milling process it is at least made more difficult for fragments to break off undesirably from the traffic surface.
