ABSTRACT:
A vibratory compactor includes front and rear frame portions driven by a first hydraulic motor and a vibration mechanism on at least one of the frame portions also driven by a second hydraulic motor. A first sensor on the vehicle senses movement of a member on said vehicle driven by said first hydraulic motor, and sends corresponding signals to a microcontroller on the vehicle. A timing device sends timing signals to the microcontroller, which is programmed to convert the movement signals and timing signals to indicate longitudinal speed of travel of the vehicle. The microcontroller automatically turns a vibration means on the vehicle on or off depending on the speed of the vehicle. A second sensor on the vehicle sends a signal to the microcontroller indicating a reverse direction of travel of the vehicle. The microcontroller automatically coincides the direction of motion of the vibration means with the direction of travel of the vehicle.
