Help - Can't figure out how to fix hydraulic leak on Kioti CK2620

Hi All - I am new to the forum, and also fairly new to tractors in general.
I have a Kioti CK2620 that is about a year old (first tractor).
I have a leak from a hydraulic line connection where the hoses come up and connects under / to the right of the seat. Picture attached.
There are four lines that connect into this area and it is so tight I cant figure out how in the world to get a wrench on it and tighten it.
Anyone encountered this issue before? Advice?
Trying to avoid having to trailer to the dealer to fix a simple loose connection leak, but I am baffled by how inaccessible this connection seems to be.

Crowfoot line wrenches would let you get that tightened up.

I bought some years ago and I definitely needed them when changing the lines on my backhoe. Very tight around the control valve block.

What @Racer4 said, they are called tubing wrenches also. Picture a box end wrench with a slot cut in it large enough to get over the tube and then slide up to the fitting and tighten.

Thank you both so much.
I will order a set and see how it goes.

In some cases you may have to remove a line or two to gain access he problem. Just be 110% certain to identify which hose goes where so don’t create it doesn’t work problem…

When I bought my used Kubota, it leaked from the valve manifold. The guy who sold it to me said it was no big deal. He said he just topped it off once in a while. He said it needed some kind of repair or other. I think he said it needed new couplers.

The valve was installed so everything was very hard to access, and because I assumed this guy wasn't stupid, I figured I would just top it off until I felt like having a dealer fix it.

One day I removed enough stuff to get at the couplers, and I tightened things up. Leak gone.

Made me wonder if the previous owner had any idea how things worked.
