the milling drum 9 with the chisel devices not shown arranged thereon and discharges the loosened milled material via the discharge belt 11 a milling track 40 having milling edges 41 and a milling bed 12 is formed in the ground 8 the depth of the milling bed 12 depends on the set milling depth of the ground milling machine 1 the stripping device 30 can be adjusted by means of the height adjustment device 15 the stripping plate 14 is guided either directly on the milling bed 12 in a scratching manner or above the milling bed 12 in the first case almost no milled material remains on the milling bed 12 whereas in the second case milled material is left in the milling bed 12 the stripping plate 14 fulfills multiple functions on the one hand it strips over the milled off surface of the milling bed with its bottom edge 16 behind the milling drum 9 when the bottom plate 13 a is lowered and thus scratches milled material into the interior of the milling drum box 2 when in a position resting on the milling bed as an alternative the stripping plate 14 may also be adjusted such that its bottom edge 16 is spaced apart from the milling bed and carried along during the milling process then for example a certain amount of milled material is left on the milling bed during the milling.
