Another thought, which may not apply here at all, is to check to see which quick couplers you have. I recently learned the hard way that pin point (two stage high pressure coupled) couplers will NOT work with Ford deluxe remote Leverless couplers. The tractor can supply oil, as the oil pressure opens the seat, but the pin/ball arrangement does not engage properly on the tractor. It remains closed and will not allow return oil. These couplers (I forget the brand name) will work on the older lever operated couplers with some restriction (hoses jump, chatter and whine). I have not checked to see if they work on the old type leverless couplers on the open center systems found on thousand series tractors. This one stumped me for a bit, as I thought the problem was in the valve bank on my harvester, not the hose end. To make a long story short, these particular male hose ends will cause the problem you describe, if your loader is run from the tractor's deluxe remotes. Also if ATW/WA is correct, and the return hose is collapsed or somehow restricting the return, there should be little or no pressure at the coupler tip. Lightly push the tip on the loader frame or some steel object to see if there is any pressure there. If the tip does not want to release, don't force it or you will get a lot of high pressure oil, which can cause serious harm, or the loader could drop on something. Best done close to the ground, and wear eye protection. Be careful. Also could be a blockage in the valve. It would help to know the tractor / loader combo. Just a few thoughts.
