Kubota Flat Hydraulic Connectors - HELP

JeffroL · Aug 14, 2022

Hi, my Kubota M7060 has flat faced hydraulic connectors for the front loader hydraulic hookup. I have a lot of different implements, and EVERY time I go to change them out the hydraulics in the attachment are so pressurized I cannot connect the hoses. It does not matter how much I try and relax the pressure by working the thumb switch and the front loader hydraulics there's always pressure in the lines. When I disconnect something I'll just for grins reconnect it and it always goes on easily but by the time it cools down then I get back the next time no way I can reattach it. I have to back out the hydraulic lines and bleed off pressure then put everything back then I can attach the implement. It takes an hour or more to do something that should take 5 minutes. Does anyone have experience with this? What are my options here because this is intolerable and it's affecting my work day. Thanks!

I haven't had an issues like that. When I Googled Reliving Pressure in Flat Faced Connectors it says they done have that problem! LOL

Haha, well lemme tell ya....they DO.

. Right now I'm covered in hydraulic fluid and I just spent about 30 minutes cracking fittings relieving pressure and then it snapped right together. I've never had this problem with the regular pioneer fitting so I'm tempted to just rip every single connector off and replace them all.

Got the same problem on our Massey. Before I hook up the lines, I just use a screwdriver to push in the detent. A little fluid comes out but it relieves the pressure.

Wasn't aware that Kubota was using flat faced connectors on anything but the skid steers. I believe I'd change them out to Pioneer push to connect, breakaway couplers and be done with it. NONE of my hydraulically powered implements have flat face couplers, they are all Pioneer.

I'm on that thread as well and again I have no connection issues with my Pioneer couplers and I don't need a 'squeeze tool' to connect them either. If there is residual pressure in the male end (implement end), I just take a brass punch and a small hammer and pop the inner check ball to relieve the pressure. Far as I'm concerned, other than on a skid steer, they are worthless and I'd never use them.

i have to use them on my front snowblower (higer flow rate than pioneer) as their removal would void my warranty. now that the warranty has expired, i could swap them out, but with the new tool, why bother.

i also have pioneer fittings on my tractor, and only thing i dont like about them is they tend to leak if nothing is attached. flat faced are also easier to clean of debris and dirt.
