OP
That coupler is completely different than the ISO type i was referring to. I suspect that you can't push balls in without pushing inner sleeve forward, like what happens when the correct hose end is inserted. Your coupler looks fine. You just need the correct hose end.Yep, balls, plural. #3 in the picture. The ones you can see around the sides in this pic. I cannot push those in with the tip of my leatherman. Should i be able to?

Ok, is this the right fitting? I got it from my neighbor down the road. He said it was for an old John Deere. However, it doesnt fit. It seems like it would fit if those little balls inside the remote hydraulics fitting would compress.
