What hydraulic quick coupler do i need? (Pics)

[capekubota]

I have a 1988 B6200D and am installing a new to me B2551 front mount snowblower. The snowblower already has hydraulic hoses with female quick couplers that measure 3/4" inside. So for the two available ports on the tractor side, I need to male quick couplers.

I'm not sure what thread and size male quick coupler I need. My local Kubota dealer was no help. Can anyone tell from these pics?

They look to be 1/2 pioneer couplings.

Easiest way, unscrew a coupler from the hose, take it, and the cap/plug from the tractor valve, to your hydraulic shop and they'll fix you up with the correct items first time.

I agree with wolf man, they look like 1/2” ISO 5675 “AG” style fittings. Are there any numbers on them?
