The other day I started building a 3 PT trailer hitch for hauling my wood chipper and trailers around the property. So far the cost is just over $50.00 for all the materials that I needed to build it. The two main beams are 2" x 3" steel. The top anchor points and lower brackets are 1/4 steel welded to the ends of the stock. The lower brackets were doubled up for extra strength and welded together. The hitch itself came from Harbor Freight. I ran out of gas for my mig welder and will be getting a new tank today to finish welding it up. I'll be sand blasting and painting it hopefully this afternoon. Then I will post some pictures of it.
