I bought a JD 310SE at an auction, that has a hydraulic problem. The backhoe seems to work to some degree, not optimal, but the loader will barely move. I'm aware that the SE, unlike the E has a two-stage hyd. pump that I believe works together with a switch on the seat in conjunction with a solenoid on the pump that increases the flow when you need it. Anyway, if someone has run across this issue before, maybe you could tell me what it was. If I don't hear from anybody, in the meantime, I will go through the regular things, suction strainer/filter, pump relief valve, pump worn out, control valve relief valves, to see if anything helps. I'm wondering also, if the pump is putting out too much pressure and it's opening the relief, in that case I should check the pressure that the pump is putting out. Thanks for any help. Craig
