Abstract:
An earth working machine includes a drive configuration and a working apparatus releasably connected together by a bolt component. A bolting moment bracing arrangement is connected or connectable in bolting moment-transferring fashion to the bolt component, and includes a bracing region that is embodied for bolting moment-bracing abutment in a bracing bolting direction against a counterpart bracing region, the drive configuration being embodied to be driven to rotate, in a rotation direction codirectional with the bracing bolting direction, while the bracing region is in abutment against the counterpart bracing region.
