Coupler styles--why are there 2?

[rjkobbeman]

If you have a part number for these, I would be curious to see it. I've been looking through my Parker catalog, and on their web site, and I can't find anything like these.

OK. I will publish the part number when I get home. I can also give you the Kubota part number as well.

My Kubota uses a bracket to achieve push connect / disconnect. My MF uses connectors straight into the valve block.

When you shove the connector in you see the inner ring sink in as part of the action.

Would you guys that have those new type hyd couplers, verify that in order to remove the hose, you simply pull on the hose. I understand how the lever release and the bracket release work, but to just pull on the hose doesn't make sense. If that is true, then a limb or whatever could catch the hose and pop the connection, and some damage could occur, by disrupting the hyd flow.

I do it all the time. And yes, if something catches on it -- and there is not hydraulic pressure going through the line at the time -- it will disconnect.

Here is an past from the first page of this thread:

I have push/pull QCs for my backhoe connections - and I HAVE forgotten to unplug the QCs and driven away from my backhoe a couple of times. Push/pull QCs are brilliant - would've surely ripped the the hoses out otherwize. I don't know why the single-direction QC collars exist, except perhaps for reduced cost.

What I have is conventional sleeved QCs, but with 2-direction sleeves, mounted in a break away bracket - I don't have the wicked-cool no-collar gizmos that the PO evidently has. The dual-direction collar mounted in the break-away bracket creates a simple push-to-connect, pull-to-disconnect system. It is still brilliant.

Oh, I see.

Here is an old thread that explains the rear remotes. Another TBNer was trying to find the correct fitting for his OEM coupler. It is the same coupler as mine. In the thread the Parker number (on the female coupler) is listed. I originally found this thread when I was trying to find what plugged in to my remotes. I searched on the part number on my coupler in order to find this thread.

I called Parker and found out some data about those couplers. It seems that they were a propriety coupler to mate up with Pioneer 8010 coupler, and made for Kubota. They say they were used until 09. The cost on those couplers are $78.00 ea.

The Parker guy said you could not find them on the Internet. Theye are listed in his parts book.

I have a 2010 Kubota -- build date somewhere around May 2010 (I don't remember exactly). I have those fittings.

If Kubota isn't using them any longer, I'm sure they are just installing them until there stock is empty. I'll have to check on my dealers lot.

Because they are not found on the net, it was really confusing searching for the correct male fitting. It turns out they accept the Ag standard male fitting, however the female fitting on the tractor doesn't look like anything found on the net in regards to that standard. It was not obvious that they accepted Ag standard males.

As far as those fittings... I like them. They are easy to clean and don't have a collar to get gummed up.

I understand they can get pulled apart, however thay may not be a real problem since they are in the back. Who knows... I certainly don't have enough seat time to know.

I outfitted my 3rd function on the FEL with the skid-steer couplers.

I have six rear remotes on my L4330 and another on the FEL off a Long 3rd function valve. Three of the rears are "Kubota" and they are "push-pull" ...push on to connect, pull to disconnect and they are great. The other three rears and the FEL auxiliary were slip-collar and a tremendous pain to connect (although they, too, were "tear-away"-pull to disconnect).

I changed out the 4 sets of slip collar and installed the push-pull. Becuse of their placement, you needed two small hands and one large one to connect the rears. To the OP: why would you want to go back to the slip-collar variant? Much less convenient, IMHO. Your dealer's mistake was your good fortune.
