Abstract: A vibratory ride-on roller machine includes a chassis supported on front and rear vibrating drum assemblies that compact the surface on which the machine travels. The machine is controlled via a control assembly including a control lever. A number of control elements for controlling operations of the roller machine are located on the control lever, the operations including one or more of turning the exciter assembly on and off, switching between exciter assemblies, controlling the level of vibration of the exciter assemblies, controlling a spray assembly, and sounding a horn element. The control elements are advantageously positioned to enable operator actuation regardless of the operator's orientation on the roller and regardless of the position of the control lever within its operating stroke.
