Abstract

A construction machine for the treatment of ground surfaces includes a machine frame and a work drum supported from the machine frame and including exchangeable tools fastened to the work drum. A drive line includes a work motor and a transmission connecting the work motor to the work drum. The transmission includes a belt drive and a reduction gear. An auxiliary drive is mounted at a location on the construction machine and includes an auxiliary drive motor. The auxiliary drive has a first configuration in which the auxiliary drive motor is coupled to the work drum via at least a portion of the transmission to rotate the work drum. The auxiliary drive has a second configuration in which the auxiliary drive remains mounted at the location on the construction machine and the work drum can be rotated by the work motor.
