Abstract
An earth working machine (), encompassing a drive motor () and a working apparatus () drivable by the drive motor () so as to move rotationally, the drive motor () being connected to the working apparatus (), for transfer of a torque, with interposition of a shiftable transmission () comprising at least two gearing stages having different torque transfer ratios, is characterized in that by means of a first gearing stage of the shiftable transmission (), an input shaft (), coupled on the input side to the drive motor (), of the shiftable transmission () is connectable in torque-transferring fashion directly to an output shaft (), coupled on the output side to the working apparatus (), of the shiftable transmission () so as to rotate together at the same rotation speed; and by means of a second gearing stage of the shiftable transmission (), the input shaft () is connectable in torque-transferring fashion, with interposition of a transmission assemblage (), to the output shaft () so as to rotate together at different rotation speeds.
