Abstract
A system for damping incipient oscillation in a linkage such as a backhoe assembly includes a crossover valve that connects the two supply lines that provide hydraulic fluid to a linkage actuator such as a boom swing hydraulic cylinder. The crossover valve is configured to open in response to the deceleration of the backhoe assembly.
