Thanks slowrev, but I can't find it. I'm not trying to really invade on anyone's territory. I just had a need for a specific implement and with my background and resources I designed what seems to be a bullet proof professional looking device. I was just wondering if there would be any interest for such an item. Mine is somewhat unique as I'd never seen anything like it before I made it. If you have a link to Northern Hydraulics product I'd like to see their model. Mine was designed giving a larger footprint for strength and stability to the drawbar and has additional strengthening aspects for both vertical and lateral support. It is in no way light, but it also would not be very expensive. It looks like it would work great with "Pat's Easy Change" system. His system looks fantastic and was something else that I was going to try to design. Looks like his system is pretty well perfected and gets my vote. Gotta get one. Again, my post was to see if there would be any interest in my invention. Depending on what all the buyer would want with my product, it would likely sell for around $62 professionally tested, finished and painted.
