I recently bought a JD 450 sickle bar mower that has hydraulics and I didn't pay attention when I brought it home to the lines. The male end is too small for my valve that is on my massey 231. I believe I've read or seen a video that stated their is an adapter and possibly that older JD equipment was using their own valve size? If I remember correctly, all newer equipment-tractors now have a standard valve size? What size do I need to pick up, excuse any improper terms lol.
