Abstract
An implement vibration system and method is disclosed that includes a vibration activation device; an electrohydraulic mechanism and a controller. The controller monitors the vibration activation device and sends movement signals to the electrohydraulic mechanism to control implement movement. When the vibration activation device is activated, the controller sends vibration signals to the electrohydraulic mechanism to cause the implement to vibrate. An operator control can send implement commands where the movement signals are based on the implement commands, and when vibration is activated the controller can superimpose the vibration signals on the movement signals. The vibration signals can cause a hydraulic cylinder to repeatedly extend and retract. An electrohydraulic control valve can receive the movement signals and control hydraulic flow to the hydraulic cylinder based on the movement signals. The vibration signals can be complementary signals. The amplitude and/or frequency of the vibration signals can be adjustable.
