TN 65 Hydraulic Quick Couplers are leaking

[aczlan]

You might have pressure built upside, in which case you need to relive some pressure. Can you take a picture? I have never seen a coupler without at least a release pull back collar.

It might be like the Kubotas and have the coupler mounted by the collar. If that is the case, the hose will just push in and pull out. Pushing/pulling on the hose will cause the collar to move in relation to the rest of the collar

All I see is the spring-loaded cover and no collar to pull back on.

Push the male tip in; it should lock. Pull the hose, the tip should disconnect.

Try just pulling the hose out after shutting off tractor and working levers to relieve pressure. If it doesn't come out fairly easy then try pushing in on the plastic collar as it may just be snapped on the release.

IIRC, push then pull quickly. That is, for the one handed version.
If you haven't had them off in a long time, they can get sticky and corroded in the area the spring loaded part sits (I am sure there are better ways to say that).

I have had similar issues as stated by the Tomseller on my post hole digger (skid steer type 2 handed connectors).
