Connect-Under-Pressure, Breakaway Quick Connect

[MtnViewRanch]

I thought the handle I see in the picture was the pressure relief method. That's what the dealer told me, as I have two of these valves on the 3rd function. My rear couplers are those hellishly complicated (no collar to retract) type. Just press in.

The easiest way that I know of to uncouple the no collar type coupler is to push in and then pull out all in one quick motion. They come out quite easy using this method.

The levers are just ball valve shutoffs.

The quick connects that came with the remote kit for my L4330 are marked "Pioneer 8010-4". They have a spring-loaded collar that releases the locking balls inside the coupler, but it has a devilishly strong spring. And the collar is covered by the remote mount. If these are supposed to be "just push in", it would take godzilla to connect them! I assume the same to disconnect. And this is without any hydraulic pressure, which will make it worse. Any tips for how to connect and disconnect them?

My first guess is that you do have residual pressure (on either side of your connection).

However, if they are two-way QDs (as it sounds by your description) you should be able to pull on the tractor side hose, 'behind' the female QD, while pressing the male QD in. This might help the connection.

A picture would help me and hopefully other, more experienced members, will comment.

On our L3830, we have some quick connects that are a VERY tight fit in the OEM quick connects and others that pop right in. All are Pioneer quick connects, no real rhyme or reason why one works and another doesn't.
They are not however, connect under pressure (as far as I know). The easiest way to get them to connect is to shut the tractor off, then move the levers back and forth to relive the pressure.
If either side has pressure, good luck getting them to connect.

i just bought 2 sets of these as i get extremely frustrated trying to change out my grapple.
they are on sale for $99.99 right now.
the problem is this.
my Massey 1440 uses the same size larger couplers as come in this kit but uses a male and a female...this kit is 2 females.
my Kubota M6060 uses the smaller size couplers as well as a male and female.
i was trying to put 1 on each tractor to move the grapple between the 2 tractors as needed.
any suggestions?part numbers would be greatly appreciated.

Luke.... this is before they are even installed, so definitely no residual pressure.

So you tried putting the male coupler in without the female being mounted?? This would be extremely difficult. I believe that the female side needs to be installed before you are going to be able to couple them. You are talking about this type of coupler, correct? :confused3:

No worries, it should be easy to make this happen and I'll give it my best shot at helping.

As I recently discovered, the only breakaway QDs must have the female QD attached to the tractor. So I just switched all my attachments to have two male QDs. I marked these male QDs with red or yellow electrician's tape (the valves you bought are similarly color coded). This way you don't mess with which operator input opens or closes your grapple.

The Pioneer valve sets you bought need your grapple to have to male 1/2" 'pioneer' style QDs. A 'pioneer' style is like saying Xerox. Many manufacturers, including Pioneer make these connectors to a common industry standard called ISO 5675 with 1/2" body. These almost always have female 1/2" NPT (pipe threads) for the hose to connect to. Your grapple hose may already terminate in 1/2" male NPT threads otherwise you will need an adapter.

Your kubota 3rd fxn kit comes with a different ISO standard QDs (ISO 7241-1 series B). I just switched everything over to iso 5675.

So at a minimum you'll need 3 male 1/2" 'pioneer' QDs. Available at your local TSC or similar. You will also need several adapters. For my kubota I think I needed two 3/8" female JIC to 1/2" male NPT to hook up the breakaway valve. You may need no adapter to put the valve set on your Massey. For your grapple my guess is you'll either need no adapters or two 3/8" female npt to 1/2" male npt. All should be readily available.

I'm glad a real expert chimed in! And I even agree!
