If it is using the original rod controlled valve it should hold the door at any position other than all the way down. If it does not, the most likely issue is a bad lift cylinder. This would allow the oil to leak past the piston and return through the hose you plumbed in. To assure this diagnosis, lift up the door and block it with a 2X4. Remove both supply line and the return line that you plumbed in from the reservoir, and cap the supply line, put the return line in a bucket to catch any fluid. Remove the 2X4 carefully, from the door and watch for fluid to come out the hose. It should come out just a little at first, then stop. If the door returns to the closed position, the cylinder is leaking internally. If the door stays put, the issue is with the tractor. The pump control valve might be out of position with the control lever/rod assembly, or it could be a bad valve internally or pressure regulator. Make a stop to prevent overcentering the door, or a shorter cylinder, or a spring to push it back. Jim
