No adapters. If there where, they would likely be more expensive than just changing the couplers.
Which is more common: 1/2" or 3/8" couplers?

My local TSC had one set of what I think will work. They are pioneer 4050-3p and 4010-3p. From what I've read online they are compatible but the male end is a little shorter than what's on my tractor, not sure how much that will matter.

4000-series pioneer/parker couplers are the typical AG ISO 5675 couplers.
If kenny is right, and your tractor does have the 7241-B couplers....then they are not compatible. So try it. If they dont work, you can either take them back and get the 7241-B series couplers (which are parker 60-series), or you can just buy another set at TSC and swap both the tractor and grapple.
Just studied the pics up close now (was on the smart phone when posting earlier). There are subtle differences between the B-series and AG couplers. But I believe kenny is right that those are B series. On the male side, the groove that the balls lock into is pretty far down the coupler body. More-so than on a AG style.

I actually decided to change it to the flat face 1/2" skid steer style on the tractor. Cost more but figured it seem to be a little more common. I'm having another issue now. The male end on the grapple will not lock into the female end on the tractor it goes in, just doesn't click and lock. They're the right couplers, the female on the grapple goes in to the male on the tractor just fine but the other will not.
Even when I have the female end off the tractor it takes every bit of power to get it to lock in to the male end of the grapple. I was able to connect the male/female pioneers I just bought into each other just fine so they seem to be ok. And the two on the grapple go into each other just fine. I took the entire line w/the male end off the grapple. I just might re do that entire thing. I did notice the center part of the male end on the grapple would get stuck about half way down sometimes not sure if that has anything to do with it.

I have had issues with the flat face couplers on mine too. Being a low spill design, any residual pressure makes it impossible to couple. Where as the regular style of coupler will allow a little oil to ooze out and relieve pressure.
I have tried every combination of engine off and cycling my diverter valve but I still can never get my hoses coupled. I thought it was just me, as others don't seem to have issues. I guess it ain't just me, if you have tried bleeding everything.
What works for me.....my grapple is controlled with a diverter and not a third function. And controlled by the lift/lower spool of the joystick. So (even with tractor running) I can detent the joystick into float, and wrap a rubber band around the trigger to energize the diverter. (Which opens the grapple hoses to tank being in float mode). That seems to be the only way I can ever get both hoses hooked up.

I changed mine on the third function on the tractor to 1/2 for it to work with the grapple. I can go find out which couplers they are exactly if you'd like. Works perfect and no issues here. FWIW, I do shut off the tractor then turn the key to the first position, toggle the third function level a couple of time, wiggle the joystick around a few times and then go connect the couplers up front. Same process for the disconnect...

I don't think it was an issue w/ pressue or anything. It was still very hard to get in/almost impossible even when I took the coupler off the the tractor and tried putting it on the grapple coupler. I think it was just a defective coupler. Tonight I did replace the coupler/line going into the grapple and it does plug into the tractor fine now. However I can't seem to find what kind of 1/4" fitting goes into the below T. Anyone able to point me in the right direction? What I thought would work and found locally isn't quite deep enough to get the threading started. The hose they where using is a Parker 471TC-4 WP and the fitting that came on the hose works with that T but I just can't seem to find it locally. Once I find that fitting I'll be back in business....I hope.

That is a JIC fitting, probably -04 (1/4") or -06 (3/8")

Yep, JIC for sure. Cant read any of the numbers on the fittings that ID their size. If they are the approximate size of a 1/4" pipe nipple....that would make it a 3/8 JIC fitting.
If you have some calipers, measure the OD of the threads and you will know for sure. Several charts online that list thread sizes of JIC. Here is one such chart https://www.surpluscenter.com/images/techhelp/JIC.pdf
Another option, though there can be some variations especially on older stuff.......what wrench size did you use on the hose to remove it?
9/16" wrench would make it a -04 JIC and an 11/16" wrench would make it a -06 JIC fitting
