I have a 2002 Deere 4210 that came with the dual SCV
I just added a third SCV to it, and now have the rear hydraulic connectors. Awesome, right?

But... the old, apparently "Deere" connectors are smaller than the new connectors that say nothing more than Pioneer around the collar.

ID on the new fittings is about 0.94" while the old female fittings are smaller.

I've seen "Deere" "Pioneer" "ISO" and "AG" all mentioned, with some references calling the latter 3 all the same thing. But nowhere have I seen anything that says "Measure your connectors".

Without going to TSC or someplace else and buying one of each, how can I tell what the heck is on my tractor? All I need to do right now is buy some new lines and connectors to hook up my belly mower to the 3rd SCV. Seems like it should be pretty straightforward.

It really can't be that difficult, can it?

TIA!

Umm. Yup!

If there is no joy talking to the dealer, try a hydraulics shop such as the Parker Store.

Good luck. If Deere has changed suppliers, you're going to need it.

Here is a fitting identification guide with a free download option that has been helpful to me:

Thanks to both of you.
I went to Tractor Supply today and brought my digital calipers with me. Looks like maybe (?) the new Pioneer fittings are ISO (which means little since they don't seem to be an even number in metric or SAE). I found some fittings that look appropriately sized. Bought fittings & elbows & reducers & whatnot. Naturally I bought too much of what I didn't need, so I need to buy another fitting or two to finish the job tomorrow. We'll see if it works. This stuff really shouldn't be difficult.

I hope you bought forged or machined hydraulic fittings (3500 psi rating) and not cast water, oil, and gas (WOG) fittings (600 psi rating).

The difficult part is learning what can and cannot be done. Actually doing it is quite simple.
