Very helpful looking at other folks ideas. I thought about what I needed which was a pintle hitch, ball hitch, and a way to quickly hook up chains for logs. To establish the optimum ball height, I took measurements of my hitch heights of my two trailers and the height of the lift arms and top link pivot points on the tractor vs. the ground. Take your time and make it so the links remain somewhat parallel to each other. As for materials, I got the hitch at NT for $60. I bough some c-channel scrap from the steel retailer for about 50 cents a lb. Cut the steel with a 4-1/2 grinder and cut off wheels. Squared off my corners on a bench grinder. Drilled the holes in the steel to mount the hitch, lift arm pins, and top link holes using a drill press. My Mrs. added cutting fluid as I drilled at the lowest speed my press can go which was about 25% faster than I wanted. Just a little patience, moderate pressure and a generous amount of fluid cut the holes without any pucker moments. Once all the pieces were ready to weld I did a root pass with 6013 rod and went back over with 7018. The pieces on the sides are set inboard by about a quarter of an inch so I could "cheat" and weld into an angle. I welded hooks on the corners. These hooks made to catch the links on the chain I use, which is a big time saver. It is easy for me to wrap a chain around the end of a log and then into one or both hooks, and lift the log up just a few inches to drag it. So far so good with all welds holding as I drag 12 ft 16 inch dia. oaks from the forest. Trailer hookup is fast, but I am getting spoiled by having a hydraulic height controlled hitch vs. a truck hitch. Thanks to all of you for the inspiration.
