Abstract
A machine comprising a vibratory compactor assembly having a cylindrical drum connected to the machine with an axle. The assembly has a shaft extending concentrically through the center of the cylindrical drum that has a first end and a second end. The shaft has an electromagnet between its first end and second end. The electromagnet can receive electric current to create a magnetic field that applies an attractive magnetic force between the shaft and the drum that pulls the shaft and at least a portion of the drum toward one another.
