ABSTRACT:
A system for reducing oscillations of an implement carried by a vehicle in a lifted position during travel. The implement is coupled to an implement positioning system including an actuator for raising and lowering the implement in response to a control signal. The system includes at least one load sensor for sensing implement load, a position sensor for sensing implement position, and a control circuit configured to generate a control signal to the actuator in a first manner based at least upon implement position and in a second manner based at least upon implement load. The control circuit transitions from the first manner of operation to the second manner of operation upon detecting oscillations of the implement beyond a predetermined magnitude. The control circuit improves roadability of the vehicle by operating in a roadability mode including the first and second manners of operation wherein the roadability mode is entered based at least upon the implement being in a lifted position and vehicle speed being greater than a predetermined threshold speed.
