Abstract
The eccentric assembly includes a tubular section, an eccentric weight, and a counterweight. The eccentric weight is mounted within the tubular section such that as a motor rotates the eccentric assembly, the eccentric weight generates vibrations that are transferred to the drum assembly of the vibration compacting machine. The counterweight is slidably coupled to the eccentric weight and moves between a first position where the counterweight contacts the eccentric weight and a second position where the counterweight contacts the tubular section.
