If I were in the hydraulic business and couldn't come up with a better coupling than the standard quick coupling I would have to shoot myself. I'm sick and tired of dealing with these fittings. Googling, I found European units with a lever handle that actually are quick couplings with a single acting lever for 4-6 or more fittings. Today I removed the snowblower and installed the bucket on my JD 2720. This is not an old tractor,(2012) and today with the attachments would cost 35k. The process sucks just as much as I remember from last year. The loader has been in heated storage on a smooth concrete floor for 7 months. Why do I have to use a wad of paper towels and shove with all my might against the seating platform to release the pressure to get these fittings so that they will engage and attach? Fluid all over my hands, all over the floor, all over my tractor. My tractor has 225hrs on the hobbs and I've got a trash can cover on the floor under my hydraulic fittings so that I don't get fluid all over my new floor from leaking fittings as my tractor spends most of its time just sitting there looking pretty and leaking. THIS SYSTEM ABSOLUTELY SUCKS!!!!! There is no excuse for this. My tractor has leaked since about 50hrs. It's time for all respectable manufacturers to find a solution.

heck JIC 37 degree flairs only need two wrenches to make or break any connection. Takes a minute or two.
You are right. "quick couplers" are just unwanted complication.
Oh! I'm waiting for your "better idea". Be prepared to defend your patent.

Before you unhook do you turn your tractor off and cycle the controls in all directions for a few seconds. Then when you’re ready to hook back up do the same? I don’t ever have issues with mine and that includes front and two remotes in the rear that get used frequently

Rustyshakelford, I will try that next time and hope it will help but ultimately, imagine just lining up the four fittings and swinging a lever to engage. Done! No matter if I do as you suggest, pray to the Gods, watch the Zodiac, roll three snake eyes, this process should not require this. Old, antiquated fittings that require a special touch, is 1970, not 2018. That's nearly 50yrs. I will never believe this system to be adequate. Like I stated in my original post, it sucks.

Same here.
I connect/disconnect my loader, backhoe and rear remotes often and very rarely have an issue.
It's because you do it often that you have no problem. It's when things sit and relax for months that it becomes difficult. My tractor is a 2012 with 225hrs. It doesn't see a lot of use. Today was the first time it was started since our last snowstorm that required snow blowing. That was in March. The bucket was removed in November and attached today, June 10th.

Page 38 shows shows some "quick couplers" with multiple ports. Most of the modern combine headers use a similar type system for detaching the header from the combine for transport.
Your right, most of the "off the shelf" pioneer type couplers can be a real messy pain. Some good suggestions in the above posts for easing the pain. I sometimes relieve pressure in a hose by pressing the male tip down in a can or some such receptable to catch the "splurt" of fluid. The hose can build up pressure even when disconnected due to temperature change.

Hey, I like that system! That fast connect beats the **** out of quick connect! It looks like the European units I've seen. "Splurting the fluid"? Sounds a bit like, "priming the pump". I doubt there are many below the age of 40 who have heard either term. Hence, antiquated. A unit like the one you referenced on page 38 should be standard equipment on any new tractor today, preferably universal fit and across all brands.

If you bleed the system properly and don’t have heat expansion to deal with there’s virtually no problems. And my CTL has a self bleeding value so a slightly better system does exist.
Self bleeding valve? Does my loader have this? I don't think so but maybe I'm missing something? After 7 months and from highs of 40 degrees to today's 80, heat expansion is going to be an issue I think. Your "slightly" better, is probably a correct assumption. A single lever to snap four fittings in place, would have it all over individual struggles with 4 separate fittings. I don't build tractors but even I know this. Why doesn't JD?
