Hydraulic fittings - Pioneer, Deere, ISO - Educate me

Anonymous-0 · Dec 3, 2009

What are the pros and cons of the different types of hydraulic fittings? I recently upgraded to a tractor with hydraulics, a 4020 with two SCVs. I also purchased a used hydraulic post driver. It has Pioneer fittings, so I can either get some crossover Deere male to Pioneer female adaptors, or replace the Pioneer male ends on the post driver with Deere. But I would appreciate some comments on the different types before I start spending money. I assume that some are easier to attach / detach, some probably leak less than others, some are cheaper, etc. Since the 4020 uses the Deere cone type couplings, I am stuck with that at the tractor. But what would be better, go with adaptors from Deere to ???, or use all Deere? What do the new John Deere tractors use? Is Pioneer the standard? I assume that ISO fittings are newer, should I make that my standard? I would appreciate any comments.

I waiting to see what the replies are. I'm in the same boat but not with JD fittings. I got some other and some Pioneer and don't know which way to go and for me it's a major expense. bjr

I'm not a real farmer, I just hobby so consider that in my answer. I prefer to stay away from JD fittings simply because they are exclusive. If you go with a pioneer, you can hook up to just about everything, except JD ends. It's frustrating to hook up to a piece of equipment only to find those JD ends on the hoses. I have Farmalls and Molines and I always carry wrenches and hose ends in the tool box for that reason.

John Deere sells kits that replace all the guts inside your outlet and the new is ISO.
It's costly but the best way to go. Seems to me their around 150-175 dollars a remote for the kit.
IN my opinion and another person I talked with they do tend to leak a little more after with the ISO kit then original. Mark

This is something I have never got to the bottom of, seems I have to write the ASAE and get some definitions. The guy who fixes my hoses says that ISO is a production standard and not a fitting type and the type of fitting I use is a standard AG type - brand Tnucci - with a pointed popet on the male end and fits Pioneer. I don't use Pioneer, they suck and also go bad and are over-priced. Tnucci cost be about $12/fitting. My New Holland dealer treats ISO as a type. My Agco dealer calls the standard Pioneer a class 3 fitting - whatever that means. Deer now uses Pioneer on all the new stuff but Pioneer is a brand, not a type or class.

I believe that ISO 5675 is the same as Pioneer 4000, the standard ag coupler.

Kit to convert one PAIR of 4020 coupler barrels to Pioneer style is DEERE part # RE206778 @ about $150.00.

Here you can see some of the different types used.

I switched all mine to ISO and pioneer. ISO is the silver ones with 4 in a row. They will also cross back and forth to pioneer.

IH had their own just as JD had their own. All manufacturers are to be using ISO now.

At one time I had 3 older IH tractors with pioneer, then my 1980's model IH's had the large couplers 3rd from the left. My newer tractor came with ISO. So I switched the 1086's to ISO and all are compatable now.

Makes life simpler to have them all the same but it cost me also to change.

Everyone went to the ISO coupler in the early 80's, most company's offer conversion kits to convert their SCV couplers to the ISO type.

I converted my 60's JD and IH tractors to the ISO conversion cartridges and never looked back.

They work great, all brands new and old on our farm now have interchangable hydraulics, everything fits without adapters.

The JD ISO conversion in my 4020 leaked with the low friction square lip seals on the cartridges. I replaced the low friction rings with conventional O rings. The barrel slides harder, but no leaks in over a dozen years.

we call the new standard ISO/pioneer. They have the ball check in the male fitting that tends to seep enough to be oily. I have some compatible male fittings that have a pointed tip with seals on the inside. They say "International" on them and don't seep.

Just buy new fittings just make sure they have the same threads as your hyd hose cheapest and most simple way to solve your problem .1 farm I worked on had every color of equip known to man so I carried a box of fittings in the cab all the time .
