ABSTRACT:
An improved walk behind soil compactor having a double vibratory drum and an articulated frame. The compactor includes a rear drive unit having a pair of drive wheels and a forward frame is connected to the forward end of the rear drive unit by an articulated joint. The forward frame is attached through isolation mounts to a drum frame that includes a vertical support plate. A horizontal shaft is journaled with respect to the plate and a pair of drums are secured to the shaft on either side of the support plate. A power operated drive mechanism carried by the drum frame is connected through a gear drive to the shaft to drive the drums and a vibratory unit mounted on the drum frame imparts vibration to the drums. As the drums are supported solely from the central vertical support plate, the compactor is capable of compacting soil immediately adjacent to vertical walls.
