Abstract
A construction machine for the treatment of ground surfaces includes a machine frame, a drive motor, a work drum supported from the machine frame and including exchangeable tools fastened to the work drum, a belt drive and an auxiliary drive. The belt drive includes a motor-side pulley connected to the drive motor, a drum-side pulley connected to the work drum, and at least one drive belt connecting the motor-side pulley to the drum-side pulley. The auxiliary drive may be permanently coupled to the belt drive, or the auxiliary drive may include an adjustment mechanism for moving the auxiliary drive between a coupled and an uncoupled position.
