Hi folks! I finally got around to installing the third function kit from Summit Hydraulics on my Kubota BX2380. In the kit from Summit I received ISO 7241-1 B series hydraulic couplers for the bulkhead mount to grapple. The Land Pride SGC0554 grapple I have has the flat face couplers on the ends. Do the flat face couplers have a better flow rate, or will it be ok to swap out the grapple fittings to the same ones I got with the Summit kit?
