Abstract
A split drum is provided for a compacting work machine and includes a first and a second drum section. A differential arrangement is operatively positioned between the first and second drum sections. Rotational power is supplied to the first and second drum sections through the differential arrangement which is connected with a propel motor. The first and second drum sections are rotated simultaneously by grounding either the first or second drum section with the propel motor. Releasing the grounding allows the first drum section to counter rotate relative to the second drum section.
