Quick disconnect that isn't

You are missing the fact that the male/ female halves are currently connected without a hose attached on one side. There cannot be any pressure. This is a mechanical problem, not hydraulic.

If you think the single hose with male tip can't have pressure on it evidently you're not familiar with a single acting AKA one-way cylinder which can have hyd pressure on hose/connector.

Read the first post again. The OP disconnected the other end of the hose that is stuck.

I wonder if the male and female halves are not the same type. There are at least three "ag coupler" standards.

I think the way to check this would be to find the numbers printed on each half and track those models down to find out which they are.

I believe that to get the 2 halves separated you are going to have to reconnect all hoses! Go through the releasing pressure procedure again after ensuring that all loads are unloaded. The clay could have created its own seal if moisture got to it inside of the connection. With enough applications of penetrating oil this should be able to be washed out. Spray it every few seconds until you longer have any dust color dripping from the connection. Rotate the connection hose end while spraying to help to break up the clay. Use a wrench or pliers if need just being cautious with the force. Wiggle clockwise and counter clockwise should ensure that any ‘connection lock’ is freed.

Ok, here's an update. The connector threads are not pipe threads, they appear to be ORB. I can thread an NPT female onto the ORB male, I can not fit an NPT male into an ORB female. I'm aware that single lines can have pressure in them, I've used double acting valves to run a single acting cylinder before. But, there is no pressure in the line, oil is dribbling out of the connector because I'd unthreaded the hose from the connector since I had several things that had to be done sooner than later so the connector got put to the side for a little while. So, when I got back to it, I put a strain relief on the hose and reconnected it to the tractor and tied the strain relief to an 800# weight. I dropped off the mower and got ready to pull, but before I did I had my wife come out and help me. - Just one more time, she and I:

1(get ready), 2(push in), 3 ( pull out) and it popped right out, just like it's supposed to.
Bottom line on this seems to be that I'm right on the margin of being strong/weak enough to get it disconnected.

Glad to hear you git it apart with a little help! Several years ago, I broke a wrist and crack several ribs in an accident. More due to the ribs but the cast on the arm did not help in trying to do anything, so I understand well that frustration.

Good to see a positive outcome.

Had you lubed it? That might have helped too.
