I have a Lee Boss category 3N quick hitch. I believe Lee makes the best strongest quick hitches out there. They are over 1k new. I didn’t pay near that for mine I got it at an auction nearly ten years ago. Anyway I changed tractors and am going to all cat 2. Looking at the specs the lower hooks are identical on a cat 3N and a cat two the only difference is the top hook is 4” higher on a 3N than on a two. Any reason not to cut off the top hook and reweld it on 4” lower?
