A vibratory compactor for a work machine, includes a support frame that defines an interior space and includes a base disposed at a lower end thereof configured to contact a work surface. A guide member is attached to the support frame. A vibratory mechanism includes a vibratory housing and includes a contact plate. The contact plate is configured to compact the work surface. An excitation device is configured to vibrate the contact plate. A guide opening is formed through the vibratory housing configured to movably receive the guide member and to permit the vibratory mechanism vertical movement relative to the support frame. At least one biasing member is disposed between the support frame and the vibratory housing and generates a selected force between the support frame and the vibratory housing when the base is in contact with the work surface.

1. A vibratory compactor, comprising: a support frame defining an interior space and including a base disposed at a lower end thereof configured to contact a work surface;a guide member attached to the support frame;a vibratory mechanism including a vibratory housing including: a contact plate disposed on the vibratory housing, the contact plate configured to compact the work surface;one or more excitation devices configured to vibrate the contact plate;a guide opening formed through the vibratory housing, the guide opening configured to movably receive the guide member and configured to permit the vibratory mechanism vertical movement relative to the support frame; andat least one biasing member disposed between the support frame and the vibratory housing, the at least one biasing member generating a selected force between the support frame and the vibratory housing when the base of the support frame is in contact with the work surface. 2. The vibratory compactor of claim 1, wherein the selected force includes a down force. 3. The vibratory compactor of claim 2, wherein the at least one biasing member includes one or more of a spring, a gas and a hydraulic fluid. 4. The vibratory compactor of claim 3, wherein the selected down force of the at least one biasing member is adjustable. 5. The vibratory compactor of claim 1, wherein the guide member extends transversely across the interior space. 6. The vibratory compactor of claim 1, wherein the guide member is supported on the support frame by a resilient member. 7. The vibratory compactor of claim 6, wherein the guide member includes two or more spaced, horizontally extending rods. 8. The vibratory compactor of claim 7, wherein the vibratory housing includes vibratory mounting brackets, each of the vibratory mounting brackets including spaced gussets, each of the spaced gussets including one said guide opening. 9. The vibratory compactor of claim 8, wherein the vibratory mounting brackets interconnect the vibratory housing and the contact plate. 10. The vibratory compactor of claim 9, wherein each of spaced, horizontally extending rods include a midsection disposed between an adjacent pair of the spaced gussets, the mid section sized to maintain a lateral position of each of the spaced, horizontally extending rods. 11. The vibratory compactor of claim 1, wherein the base of the support frame includes a skid base. 12. The vibratory compactor of claim 11, wherein the skid base includes two or more skids. 13. The vibratory compactor of claim 1, wherein the excitation device includes one of a pump and an electric motor to operate the excitation device. 14. The vibratory compactor of claim 1, further comprising a sensor operatively connected to the vibratory mechanism and a controller in communication with the sensor to receive signals from the sensor indicative of motion of the vibratory mechanism. 15. The vibratory compactor of claim 14, wherein the controller is configured to determine a degree of compaction of the work surface. 16. A work machine, comprising the vibratory compactor of claim 1, attached to and operated by the work machine. 17. A method of operating a vibratory compactor, comprising: contacting, with a vibratory mechanism of the vibratory compactor, a work surface;contacting, with a support frame of the vibratory compactor, the work surface;generating, with a biasing member, a selected down force between the support frame and the vibratory housing; andgenerating a fluctuating vertical force with the vibratory mechanism that in combination with the selected down force, causes compaction of the work surface. 18. The method of claim 17, further comprising: sensing, with a sensor, a rebound force of the vibratory mechanism on the work surface;determining, with a controller in communication with the sensor, a degree of compaction of the work surface based on the sensed rebound force; andadjusting one or both of the selected down force and time of contacting the work surface based on the determined degree of compaction. 19. The method of claim 17, wherein the biasing member is two or more biasing members. 20. The method of claim 19, wherein each of the two or more biasing members includes one or more of a spring, a gas, and a hydraulic fluid.
