Abstract: An earth working machine includes support structure and a working assembly mounted on the support structure so as to be rotatable about a drive axis. An assembly-side bearing configuration is connected to the working assembly and a structure-side bearing configuration is connected to the support structure. The assembly-side bearing configuration includes a driver configuration having a driver surface facing in a first circumferential direction and the structure-side bearing configuration includes a driver counterpart configuration having a driver counterpart surface facing in a second circumferential direction opposite to the first, the movement spaces of the driver surface and of the driver counterpart surface about the drive axis overlapping one another.

Abstract: The invention relates to a method for operating a ground milling machine, in particular a road milling machine, a stabilizer, a recycler, a surface miner or the like, having an interchangeable milling drum, wherein the milling drum is equipped with a plurality of milling tools, in particular round shank picks, wherein the milling drum has a current state, wherein a control unit is provided for controlling at least one function of the ground milling machine, and wherein the milling drum has a characteristic feature or a characteristic feature is assigned to the milling drum. According to the invention, provision is made that at least one data set containing information on the current state of the milling drum is stored in a storage unit, in that the characteristic feature identifying the milling drum is assigned to the data set in the storage unit, and this data set is transmitted to a processing device.

Abstract: The present invention relates to an earth working machine (10), comprising a support structure (30) and a working assembly (28) mounted on the support structure (30) so as to be rotatable about a drive axis (A), the working assembly (28) being rotatably supported by a first rotary bearing (57) and by a rotary bearing arrangement (77), the rotary bearing arrangement (77) comprising a second rotary bearing (76), an assembly-side bearing configuration (74a) connected to the working assembly (28) and a structure-side bearing configuration (86) connected to the support structure (30), both the assembly-side bearing configuration (74a) as well as the structure-side bearing configuration (86) being situated so as to be rotatable about the drive axis (A) relative to the second support structure area (30a) in the reference state, and both the assembly-side as well as the structure-side bearing configuration (74a, 86) being designed to be axially removable from one another and thereby separable from one another for mai
