Abstract
A method for retrofitting a swing damping circuit to a work vehicle such as a backhoe includes disconnecting a boom swing valve from a boom swing cylinder, and coupling the swing damping circuit to the boom swing valve. Alternatively, it may include replacing a boom swing valve with a combined boom swing valve and swing damping circuit that form a unitary valve body.
