This weekend I took off the hoses going to the tilt function and put a hyd. pressure/flow check insturment on it. Pressure seems to peg around 1,500 psi. though it stalls out the engine when it reaches this psi. Mind you I live at 8,700' so the engine is underpowered because of altitude. My question is this: lightly depressing the tilt pedal it pressurizes the one hose and goes to full psi (1,500) and has no flow, when you push the pedal a slight bit more than the control valve must open the return pressure hose port and the psi drops to around 500psi and has about 9 gph flow. I do not understand why, when lightly pressing the pedal it pegs the psi with no flow. Has anyone ever experienced this?</p></blockquote><p></p>
