(21) Ride control activation spoolThe Autodig system controls the bucket functions via the bucket control valve.The bucket control valve is a monoblock closed-center valve is located in the front frame. The ride control valve (if equipped) is bolted to the bottom of the bucket control valve. The R1700K Load Haul Dump machines use an electrohydraulic system. The electrohydraulic system will sense a demand for a flow change and the implement pump will upstroke or destroke to provide the demanded flow.Reference: For more information on the control valve refer to System Operation, "Hydraulic System", Main Control Valve.
