1. An earth working machine, comprising:
a drive motor;
a milling drum;
a shiftable transmission connecting the drive motor to the milling drum for transfer of a torque to rotate the milling drum at a plurality of selectable transfer ratios, the shiftable transmission including an input shaft coupled to the drive motor and an output shaft coupled to the milling drum; and
a braking apparatus disposed in a torque transfer path from and including the shiftable transmission to and including the milling drum, the braking apparatus being configured to bring the milling drum to a stop when the torque transfer path is interrupted;
wherein the braking apparatus is arranged to act on the output shaft or another component of the shiftable transmission that always rotates together with the output shaft; and
wherein the output shaft is coupled to the milling drum by a planetary gearset assemblage connected to the milling drum, and a belt drive connected between the shiftable transmission and the planetary gearset assemblage.
