What is leaking?

Is the original picture shot looking down or sideways?

Clean it up, get it dry, and operate the hydraulics. That's a LOT of fluid that's leaked and it should be pretty obvious where it's coming from.

On regular fittings I use Loctite 545. Ones with o-rings? I'd think o-rings would be for return and it would be just a matter of making sure the o-ring isn't pinched; I'd see no reason why the 545 couldn't, however, still be used as it could only help.

Use a pressure washer or a can of brake cleaner to get the whole area as clean as possible. That will make it easier to find the leak. Also in my experience leaking orings and seals don’t spray oil. They just kind of seep out. A cracked line or pinhole in a hose will spray. And those can be very dangerous. Don’t use your hand to feel around for it. Good way to loose a finger or two.

Had similar problem with my Kubota B2630 this winter. Thought it was o-rings in hydraulic valve body. Replaced those. Sill leaked. Had to bring to Kubota to take apart. They found hole/break in metal hydraulic tubing leading to the valve body. Had to replace the metal tube to fix it. Was expensive but it was fixed.

I haven't been able to get back to the property to take it apart and look but I have a feeling that is my issue too
