Why not learn to use the Rexroth valves that are on it? They're real simple to couple if you follow one simple rule. Kick the valves in float BEFORE you uncouple. Then the hoses are relaxed. When you go to recouple, kick the valves in float again. If there is pressure in the hose... push the hose fully forward while turning the coupler lever at the same time. If you do that they work fine. If the lever type coupler barrells have worn to the point where the levers don't stay engaged while you're using the hydraulics... replace the lever type with the updasted leverless barrells for those manifolds. No big deal.
There is no way in hell I'd want to go back to using full locking pioneer couplers without a breakaway... Talk about misery.
