  • Page 901: Hitch Control Valve

    Section 35 - Hydraulic Systems, 3PT - Chapter 9 HITCH CONTROL VALVE General The hitch control valve is a closed center valve that receives oil from the PFC hydraulic system. To control the pump during hitch operations, signal pressure is sent from the valve to the PFC pump. The raise and lower functions of the valve are operated by regulated pressure received from the regulated hydraulic system.
