A drive unit (5) is carried by the frame to drive the working drum. A power transmitter (6) transmits driving power from the drive unit to the working drum. The drive unit comprises a first drive engine (5A) and a second drive engine (5B). The power transmitter is designed such that driving powers from the engines are simultaneously transmitted to the working drum. The drive engines are internal combustion engines or diesel engines.",
