I have a Kubota 5030 with rear factory installed hydraulics. I am trying to figure out the size for the male connector that would fit into the female connector. At they standard my guess not. I have an opportunity to buy and try out a post hole digger that has a down pressure kit and I want to take the correct fitting with me. Any help of advice people can give me would be great. I most likely would pick them up at NAPA or Tractor supply in that my Kubota dealer is a long drive. Thanks John
