Abstract

An earth working machine (10) includes a machine body (13) having a machine frame (12) and a drive configuration (46), rotationally drivable relative to the machine frame (12) around a drive axis (A), to which configuration a working apparatus (32) embodied for earth working is releasably connected in torque-transferring fashion, in an operating position operational for earth working, for rotation together around the drive axis (A), such that when the connection is released, the working apparatus (32) is removable from the operating position in an axial direction relative to the drive configuration (46) for deinstallation from the drive configuration (46) and, for installation on the drive configuration, is conveyable into the operating position in an axial direction relative to the drive configuration (46).
