Hi Andrew, 574 and 454 are same hydraulic, from the archives: Hi Joe, on the 454, the oil pump feeds the steering in priority, then the remote, hitch, PTO and brake. The flow-divider valve give 3 GPM to the power steering and 9 GPM to the hitch system. When the valve is stuck in the bottom, you have no power steering, no PTO and if stuck in top, you have no hitch, no remote. Remove the plug and the spring, put a container under the hole, start the engine and pull the remote lever. The flow-divider valve goes out in the container. Sand the valve with a 400 sand-paper and try again. Change the filter if it's old. Maybe you have dirt in the oil, check in the filter housing when you open it. When the filter is full of dirt, it has a by-pass valve that opens and allows the oil to go directly to the pump via a screen. In this case, dirt can go in the system and cause your problem. Hope this help you. Bernard le mécano Québec Canada
