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. |

1. A vibratory roller comprising:
a chassis; front and rear rotating drum assemblies supporting the chassis on a surface, wherein each of the front and rear drum assemblies includes an exciter assembly for imparting vibrations to the respective drum assembly; an operator's seat supported on the chassis; a control lever, located beside the operator's seat and operably coupled to the vibratory roller, for controlling forward and rearward movement of the vibratory roller, the control lever including an at least generally vertically extending support arm that is movable fore and aft relative to the operator's seat and a handle that extends from an upper end portion of the handle, the handle being shaped and sized for grasping by a seated operator so that the seated operator's thumb is received over an inboard end portion of the control lever while the seated operator'fingers are received over a top portion of the handle; a first control element, located on the inboard end portion of the control lever, and accessible by the thumb of the seated operator when the operator is grasping the handle with the operator's fingers received over the top portion of the handle, for turning the front and rear exciter assemblies on and off; and a second control element, located on the inboard end portion of the control lever, and accessible by the thumb of the seated opera tor when the operator is grasping the handle with the operator's fingers received over the top portion of the handle, for switching between activation of the front exciter assembly, the rear exciter assemblies, and both exciter assemblies. |
