Why none of these scuts have flat face quick connect couplers for the loader?

[Smokeydog]

With the ag fittings always used rags and had to hit the ball to relieve pressure. Use brake cleaner to clean the females and dust covers. Always a mess.

Flat face are much cleaner and easier to keep clean. Harder to relive pressure. Connecting lines together when off tractor helps.
Made the clamping tool for ag couples for a Kubota B20 backhoe years ago that was awkward to connect. Also fit flat face connectors on the big tractor grapple.

Doesn’t take much force to connect under pressure but more than I can do by hand anymore. See a fellow on eBay is selling a similar clamp.
Bought a Waite pressure reliever tool last year. Has scared the flat face couplers into behaving and not had to use it yet. It would pretty easy to make something like it.

Came in here to post that tool from Bolt-On Hooks/Ken. I really need to get one since I can't for the life of me come up with a procedure that doesn't require me to loosen one fitting to get one FF connector to connect.

Pisses me off; biggest complaint I have about using my grapple. On the other hand, I always end up with a big grin on my face every time I use my grapple, so there is that.

That's a pretty cool tool, Smokeydog.

I wasn't giving the couplers that connect the loader hydro lines much thought last year because I didn't mow with the massey, so never took the loader off. This year, I've been mowing with it. I dunno, maybe I gotta work on my technique with them, but I find them a pain to connect with where they are, wedged behind the loader arm support. If I could just push the male coupler in without also having to pull on the ring on the female coupler, would be hella easier. Or maybe if the females weren't mounted on a bracket, but instead I could grab each one individually like with the backhoe...I don't have any problems connecting the backhoe lines.

Seems FF connectors use every excuse in the book to make ones life as difficult as possible. Oh, the temerature has risen ten degrees, I'm not gonna connect today!

I have dozens of the suckers of various makes. Not a one will connect under the "slightest" pressure. Or if having gotten wet or damp and then froze. Maybe I just didn't spend enough. I had a hard time spending the money I did, over Pioneers.

My friend just bought a new machine with these fittings. No matter what he does he has problems connecting up his grapple to them. He has to relieve the lines in order to push the fittings on. I told him just now about the tool to push these together. He said, where do I buy it. LOL

If I follow these procedures I don't have any issues installing the loader at all.

1) remove the front end loader when the oil is warm. Then when the oil warms up on a warm day it won't expand to the point of pressurizing the oil trapped in the hydraulic lines because the oil was already warm when you removed the lines.

2) I store my loader inside a building. If you remove it outside and the sun warms up the oil, the oil in the hydraulic lines is going to expand resulting in a pressurized coupler.

3) try to arrange your day so that you are installing your loader in the cool of the morning or evening for the same reasons as above. If you store your loader inside then this isn't as much of an issue.

4) Shut off the engine and relieve all pressure from the hydraulic lines before you remove them. Cycle your your loader controls several times.

5) When you drive away from or into the loader to hook it up be careful and don't bump the loader in any way at all. This is really important because if you move the loader in any way there is going to be a coupler that has pressure in it.

Sometimes just dropping a Female FF connector onto concrete will render it garbage!

We have tried everything to relieve the pressure and there always seems to be pressure on one of the tractor hoses. His 3rd functions are electrical and on the joystick. He has tried holding them for seconds, going thru each function and still one line will have pressure. It happened again this morning to him. He broke the fitting connection and it was fine.

Have not tried this tool. Same concept as the one I made years ago that works well. Not too hard to make something like this. Advantages over Waite tool is little to no fluid loss to attract dirt.

I Don’t have trouble on the tractor side.
Turn off tractor. Turn key to run position without starting tractor. Use the electrical switches to cycle valves. You should hear the valves operating. You can actually hear the difference when the pressure is relived. Try to connect. Every once in a while if the tractor is hot or after connecting one of the lines and I don’t move fast enough, I may have to cycle the valves again. So l leave the key on without the tractor running while I am connecting.
Same for connecting rear remotes if electrically operated.
Manually operated rear remotes levers must be operated with the control lever while the tractor is off to relieve pressure. One of my tractors I used a rear remote to operate the FEL grapple.

Implements I connected the lines together when storing if I can. Set out of the sun if possible. Still had to loosen a fitting to relive pressure sometimes before making the clamping tool. At first it was frustrating leaning new tips and tricks.
