Abstract:
A road milling machine includes a rear wheel or track mounted on a pivot arm such that the wheel or track is movable between a first outer end position projecting laterally relative to the machine frame, and a second inner end position which permits milling close to an edge. A travel drive of the rear wheel or track provides a driving force to move the wheel or track between the end positions.
