A vibratory compactor includes a frame which carries a soil compacting plate, and a drive mechanism such as a gasoline engine, is mounted on the frame and has a rotatable drive shaft. A pair of eccentricly weighted shafts are mounted for rotation on the frame and the weights are in the same phase relation on the shafts. The drive shaft carries a pair of pulleys and single belt connects the pair of pulleys on the drive shaft to pulleys on the eccentric shafts. The drive shaft is connected to the drive shaft pulleys through a centrifugal clutch, which acts to selectively connect the drive shaft to one or the other of the drive shaft pulleys to thereby effect forward and reverse travel of the compactor plate of the compactor over the terrain. |
