A work machine 10 for increasing the density of a compactable material 12 includes at least one compacting drum 14 driven by a two-speed drive arrangement 40. Compacting drum 14 also includes a vibratory mechanism 26 that is powered by a hydraulic motor 28. A first input device 54 is used to select the frequency of the vibratory mechanism 26. A second input device is used to select the output speed of the two-speed drive arrangement 40. A third input device 66 is used to select a desired impact spacing of the vibratory mechanism relative to the output speed of the two-speed drive arrangement 40. A controller 52 receives signals from the input devices 54,60,66 and responsively controls the output of a pump 22 automatically propelling the work machine 10 to a speed at which the desired impact spacing is obtained.
