ABSTRACT:
The 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 eccentrically weighted shafts are mounted for rotation on the frame and the weights are in the same phase relation on the shafts. A belt drive connects the drive shaft to at least one of the eccentric shafts, and a timing belt is connected between the eccentric shafts, so that both eccentric shafts rotate in the same direction to vibrate the compactor plate and affect travel of the compactor over the terrain.
