A manually guided roller-type compactor having a roller, a vibrator assembly, compactor frame, a drive assembly and a directional control assembly. The vibrator assembly is selectively positioned by the directional control assemble along a radial path for propelling the compactor in a forward direction or a reverse direction while simultaneously providing compacting forces. The center of the radial path is coincident with the axis of the roller rotation. The vibrator assembly may be mounted interior of the roller or alternatively exterior of the roller.
