Adapting a snow plow to my B2620 - hydraulic questions

[JJay_Bird]

As the title implies, I have a B2620 tractor. I found locally a used plow with power lift and power angle... it's a New Holland 72CB. I've already got the mounting done and waiting on two plates that a local fab shop is making for me. Next will be the hydraulic connections... and eventually the correct colors of paint!
My questions: On the joystick controls, which two fittings are lift and which two are angle? On the quick connects, can someone tell me what type and size they are? The fittings that are on the lines on this plow are males (like the tractor) so I'll need to change them.

Assuming you don't have a loader? So can I look at my 2620 loader and tell you which lines lift vs dump? Is that all you need to know?

Thanks Tim. Yes, I needed hose placement and fitting type. I’ve since figured both out but thank you for the reply.
I’m very happy with the plow set up, not so much the R4’s on the snow, especially this last blast we had with 10+ inches.
I put a set of chains on the fronts from my garden tractor. They were slightly too long but it was a game changer. So now I am looking for the right set of chains for those tires.

I am honestly shocked the chains didn’t fit better. The R4’s are 23 x 8 1/2 and the garden tractor rear’s are 23 x 10 1/2.

Standard valve setup is left spool for boom and right spool for lift.

Sounds like you are calling the quick couplers fittings. I would expect the loader side are 3/8" body size and probably not agricultural type.

The couplers are available on Amazon $14

Thanks for the reply. You are right, I was talking about the quick couplers. After a little research and measuring, I figured out they were ISO 7241-B, so I ordered four from Summit Hydraulics and picked up 4 3/8NPT to 1/4NPT adapters at a local hydraulic shop. All good now, thanks again!

Kubota seems to prefer ISO 7241-B for front implements and ISO 5675 for rear outlets.

Thanks for the reply. I searched your number on Amazon and noticed they were Summit items. Out of curiosity, I went to the Summit website and created a shopping cart... with 4 of your picks and four of the ones I actually ordered:

So now my question is, what is the difference between these two? I bought the ISO ones, and they are installed and working. The tractor-side males are original as far as I know.

Kubota does not advertise what standards their couplers are using. They give you a Kubota part number and inflated price for a black box.

I believe the Kubota couplers are also ISO 724-B so no difference other than price. Quite possibly the identical coupler. I am not sure what the body size is. The 1/4" NPT port thread would lead one to believe they are 1/4" bodies but that is not definitive. You measured the couplers on your loader - what were the dimensions?

See this portion of an interchange chart I found online. The male quick connects on the tractor are marked Faster HNV... then all I did was measure the od at the end and came up with 9/16 which told me I needed the 1/4" body size females.

Faster HNV couplers are ISO 7241-B. So the answer to your question is the only difference in the couplers Summit is selling is the price.
