I have a iseki 2-62. My hydraulics are so slow. I have cleaned the screan which was full. They didnt get any better. When I did a flow test it was only 1.8gpm at 1800psi. Very low, but when I did the test I had the 3 point down and my loader down. The loader is tied to a front outlet pipe fitting right in front of the seat. I used the back outlets for the test. When I cranked on the screw for the tester the 3point went up as did the the loader and I wasnt even touching those valves. WHAT am I a missing???? Why are my hydraulics being wierd. Is there a pressure relief valve somewere? I cant find anything in the owners manual or online. Any help would be great.
