Abstract
A vibratory compactor includes front and rear frame portions driven by a hydraulic motor and a vibration mechanism on at least one of the frame portions also driven by a hydraulic motor. Speed sensors on the vehicle determine the speed of the hydraulic motors, send a signal to a microprocessor on the vehicle which is programmed to convert the signals to indicate the vibrations per unit of longitudinal travel of the vehicle and to display the amount of vibrations on an indicator for the benefit of the operator.
