Abstract
A ride control arrangement for a machine having a frame, a ripper, a hydraulic actuator operative to move the ripper includes at least one accumulator assembly, and a valve mechanism operatively disposed between the accumulator assembly and the hydraulic actuator to either block or allow fluid communication between the hydraulic actuator and the accumulator assembly. A ride control arrangement for a motor grader with an implement operated by a hydraulic actuator similarly includes at least one accumulator assembly selectively fluidly connected to the hydraulic actuator by way of a valve mechanism.
