Hi. We just received a new LX2610SU. It was ordered with third function and flat face couplers. From online sources, I take these to be 3/8" male and female. I am trying to understand which is the first and which is the second. This is the Kubota 3rd function kit. Also, some of the implement companies don't seem to use this ( 1/2" only). Any ideas on adapting or should we only use implements compatible? It would be a shame to replace these new couplers.
