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.

Implement vibration system and method

An operator control system for a work vehicle having at least one work vehicle actuator and at least one removable attachment with at least one attachment actuator. The operator control system comprises an operator control interface. At least one control device is coupled to the operator control interface. The control device is configured to control at least one of the work vehicle actuator and the attachment actuator. A shift device is configured to shift the control device from controlling at least one of the work vehicle actuator and the attachment actuator to the other of the at least one of the work vehicle actuator and the attachment actuator.

Method for utilizing single input device and button to control multiple auxiliary functions

A work machine includes a frame, at least one drive wheel carried by the frame, at least one caster wheel assembly carried by the frame, and at least one turn assist arrangement. Each turn assist arrangement is coupled between the frame and a corresponding caster wheel assembly. Each turn assist arrangement is configured to bias the corresponding caster wheel assembly during an operator commanded turn, and to be overridden by forces applied by the ground to the caster wheel assembly.
