I was just wondering if for some reason you don't have the voltage necessary to really move the solenoid w/o the tractor running.
3rd Function Diverter pressure relief

My Kub. 9540 does just as described as well. It is in the tractor side, not the attachment. Moving the buttons on the (dealer installed) 3rd function does open the solenoids, you can hear the clikking, but the pressure is not relieved. Get out the wrench and break the fittings! PITA.
JJ, if your reading, all my stuff is "flat face" and the "push the center ball trick" can not be done on this type, what does this needle valve look like that you have mentioned? Like you said, it's prolly only a teaspoon of fluid that prevents normal coupling.

The needle valve mounts in a tee at the QD, and you release a little fluid to connect the QD's.
One other way is to plug the QD into a dummy QD with open end, just don't let it leak all you fluid out. Store above the source of the fluid.
Here is a needle valve , but they are not cheap, but will work. Actually any high pressure valve would work.

Thanks JJ, I guess that you'd just tee that valve into the line at a convienient point?
For the sake of keeping things as "tidy" as possible, do you know of a small inline type of valve that with a tiny schrader valve type type of thing. For that matter, I wonder what psi the best schrader valve can handle? Feel free to tell me I'm stupid:laughing: Sometimes I'm in the brush & sticks with either the tooth bucket or a root rake, things can get pretty ugly out there and those valves will find their way into trouble. As I'm typing & thinking, there is no reason that those valves you linked to could not go back on the loader arms at the connection between the hard lines and the hose where it main pivot is. That area is a much safer than out on the torque tube where the other connections are.

Rusty, That is why I went JJ's idea #2 - a dummy QD on an open piece of pipe. I did this for the same reason - I was concerned about a valve getting caught and either damaged or opened during use. Besides, I only need to use it when changing implements so keeping the dummy unit with the attachments means it is right where it needs to be.
Credit - I doubt the voltage is the issue. If it has enough to reliably start the tractor (it does) then it is not short on voltage. Running voltage isn't that much more than battery voltage on a good batt.

I know this is an old thread but I have the exact same issue. I cannot connect one of the flat faced connectors to the third function. I can let the tractor sit for days without running and then maybe be able to connect. Otherwise you are out of luck. Very frustrating. I'm going to switch to the 1/2" pioneer connectors I have on the backhoe. Those are reliable and seem to be able to connect. if they are under pressure, it's just a matter of tapping the tip on the front of the male connector.

This solved that problem for me on flat face connectors: Why are hoses hard to connect???
Also use it to connect the hoses together when not using the attachment:

Resurrected! I don't put my grapple on much anymore but when I do the only way is using he relief tool and typically some help from a clamp. I made jaws for a pipe clamp similar to what Xfaxman shows that help. I was looking for a photo of it but no luck. I will try to take on this weekend and post it here. It makes instant sense once you see it, but harder to visualize describing it

thanks for the responses. I was going to make a tool like that but I was able to acquire the quick connects from summit and it has changed everything.
Summit Hydraulics sent me the .5" pioneer quick connects. I think they are the same as the rear remotes
1/2" Ag Hydraulic Quick Connect Couplers, Poppet Valve ISO 5675
I received them yesterday from USPS (not sure how). Shipped Friday from Arizona. Weren't supposed to be here until Wed or Thurs.
I switched them out and wow! it works so much better. I can disconnect and reconnect with no issues on either one. Sometimes, even one handed.
The entire order for 2 m/f sets was $29.90 including shipping.
I don't know if that's useful for you or if everything is working fine. Too much frustration for me. When I did get them connected, then I couldn't get them disconnected after using. I would loosen the connector to the coupling for it to bleed a little pressure.
