What kind of swivel is it?
Aeroquip, Parker,, etc, make better ones....although, any of them will eventually leak. Most seal with just o-rings, with some also using back-up rings with them. Get into some bigger money, and there are models with ball bearings and U-cups.

At least you can fix the issue with your tractor.
Well done defining the cause.

Here's what I don't get. You have two non-swiveling ends on a hose, and the hose is short, so you can't twist one end up so it will release as you tighten the second connector. You can't rotate the part. How do you install the hose so the hose doesn't try to twist the connector when the pressure is on?

I'm delaying taking off the tractor's upper pan because I'm waiting for two DC connectors to arrive. To remove the pan, you have to pull the light sockets out of it, and they do not want to go. Twisting and greasing them doesn't help. Two cheap DC connectors will put an end to that problem.

Like I need taillights when I'm mowing the yard, but still.

I'm also waiting to pick up the patient lift I'm buying, so it will lift the pan for me. I think that contraption will be better than gold.

Can you add a JIC adapter to one end, say....the cylinder end, make a new hose with a swivel on one end, and the regular threads on the other?
They also make hose ends with pipe swivels.

I'm not sure what connections you have....so it's hard to say from where I am....

I have two swivels, but you don't seem to have a lot of confidence in them. I don't understand how John Deere did it. Maybe it's a lot easier when the tractor hasn't been assembled and you can turn major parts however you want.

Well....I am not sure what kind of swivels you have.

Pics??

Remember....if you want to be smarter than the 'engineers who know their stuff', you have to be able to redesign and replace what they designed and had someone install, so it's serviceable by a normal mortal.

It will be a while before there will be photos. Waiting for the patient lift seller to get back to me. I can't just walk over and take a picture. I have to remove the pan.

I know it is awkward at times but you're going to get it. It may require an adapter but two arms, two hands, two wrenches- how lucky we are.
