I kind of like having a bit stronger hitch and having the ability to move both gooseneck / 5th wheel trailers as well as bumper hitch trailers. Also, I don't see any chain link to attach to your draw bar to prevent the hitch from being pushed up and into the back of your tractor. Your 3 pt. hitch will lift, but does not offer any down force. If you are going down any grade and stop, without a chain holding your hitch to something (I use the draw bar), you can have the 3 pt. hitch jump up and slam your tractor.
I've designed and built about 6 different types of hitches for the 3 pt. hitch of a tractor as well as hitches for the loader. Here is a pic of my 3 pt. hitch that allows you to move both gooseneck trailers as well as bumper hitch trailers. Not shown is the insert to move a bumper hitch trailer and the chain isn't shown in this picture. As you can see, this picture is of a hitch that hasn't been painted. Also, I intentionally am not showing how my chain system works to prevent the 3 pt hitch from raising up. I put up too many details of one previous version of a hitch I designed and someone copied it and began selling it.
