Quick Disconnect Couplers

[rjkobbeman]

Hello all,

I recently installed a 3rd function valve on my tractor so I can connect skid-steer hydraulic attachments.

Since it has been a while since I rented one, can you refresh my memory on the quick disconnects on the skid-steer end? I need to know if it is 2 male, 2 female or 1 of each. If it is one of each, is there a preferred location for them?

Thanks.

1 of each coupler is needed. However, the flow of your hydraulics will determine where the put the male or female on which opening. You may only find out if they are correct after you connect your hoses and try your hydraulics.

I have two buttons on my front end loader joystick. One button causes the flow to go one way and the other button reverses the flow.

The end of my lines where the couplers go are on the right boom (if sitting in the tractor facing forward) and are side by side a couple of inches apart. Is there a standard that the implements follow that make their lines lay "better"? That was the reason for my question.

I don't think my system cares which is which.

The fact has to be stated that some machines use same fittings for pressure and return, usually male. It would be wise to have one of each, with the male QD as the primary pressure QD. It is not so important when using a hyd motor, as you can switch direction. Some rotating devices only turn in a certain direction, such as a stump grinder, trencher, etc. So if everyone knew that the male QD was the pressure, it would simplify things.

I bought Secchi quick disconnects because I was told they are the best. They might be, but I've had so much trouble getting them to come apart that I just took them off. For the amount of effort that it took to bleed the lines to remove the pressure to get them to come apart, then to deal with the mess of it, I've gone to just a male male fitting that both ends of my hydraulic lines crew into. When I take off my grapple, I unscrew the line and cap it. Time wise, it's much, much faster. Frustration wise, it's night and day.

I've never used Parker or any other brand of quick disconnect. There have been some discussion on them and from what I understand, they are all a pain to deal with.

Good luck,
Eddie

Thanks for the info.

Just to be clear, when you say male QD being the pressure, that is on the skid-steer end right?

Yes, that is correct, male QD on the machine should be pressure. That is not to say that every one applies this logic. If it is not, you can make it so, and change all the attachments to coincide. When you rest somethings, they may not be matched up. Another thing about one male and one female QD on ab attachment , is that you can plug the hoses together and keep them clean.

Thank you sir. I appreciate the help.
