I have a Pats quick hit setup on my 3PH. It works well and I have no complaints, But I also have a few implements that are not quick hitch comparable..In other words they are just basic #PH set ups with the pin and retaining pin to hold the 3PH arms on. I have a rake that i would like to use and Im thinking about having some steel welded at the end of the pin so it basically eliminates the need for a retaining pin on the post. ..Has anyone done this before ?
