1. An interchangeable unit for removing material from a ground surface, the interchangeable unit being configured for operational physical and functional coupling to a machine frame of a road construction machine, the interchangeable unit comprising:
a housing including:
a connecting section configured to physically couple the interchangeable unit to the road construction machine, the connecting section including a plurality of connecting configurations configured to mount the interchangeable unit to the machine frame of the road construction machine; and
a working section including a working opening, the working section located remotely from the connecting section;

a removal tool, mounted to the housing and rotatable about a working axis such that a circumferential section of the removal tool protrudes from the working opening;
a drive belt pulley rotatably mounted on the housing and configured to be coupled to a drive belt for functionally coupling the interchangeable unit to the road construction machine, the drive belt pulley including an axis of rotation spaced from the working axis of the removal tool;
a transmission gear unit configured to transmit torque and rotary motion from the drive belt pulley to the removal tool;
a start-up motor; and
a start-up clutch configured to connect the start-up motor and the removal tool in a torque-transmitting fashion such that the start-up motor is disengageable from the removal tool.
