Abstract:
1. A hydraulic swing damping system for a backhoe including a work vehicle with a backhoe implement that is configured to be pivoted about a substantially vertical axis with respect to the vehicle by at least one dual-ported hydraulic cylinder, and a bi-directional control valve coupled to the dual-ported hydraulic cylinder by first and second supply conduits, the system comprising: a bypass conduit configured to be fluidly coupled between the first and second supply conduits; an electrically actuated bypass valve disposed in the conduit to control fluid flow therethrough; an electronic controller electrically coupled to the bypass valve to selectively open and close the bypass valve; and a sensor configured to be coupled to the backhoe and responsive to a physical parameter indicative of incipient backhoe attachment oscillation, wherein the electronic controller is configured to
