I have a 3 pt hitch backhoe on the back of my Ford 1970 4000SU. I got all of the mechanical mounting stuff done fine so it is nice and solid back there. The hydraulic hoses plug into quick connects fed with a single spool valve under the seat. I put the valve in the up position and it feed fluid to the backhoe. The out riggers, boom and bucket move around fine until I put a load on it and then the valve pops to the neutral position. There is a inline pressure requlator on the supply hose. By backing off on the regulator I can keep the valve from poping off but there's not enough pressure to do any real work. Am I doing something wrong or do I have an equipment problem? Thanks, in advance, to anyone that will try to straighten me out. Bill
