You haven't said, so I'll ask. Does your tractor have a PTO? If so, it will be more challenging, but you can still build a hitch. Not the best, but I did it for almost 10 yrs and the tractor was fine. You want the hitch point as close to back of tractor as possible. The best hitch is where you pull the ag drawbar and remove the hitch support, then a flat plate gets bolted on and a drawbar with a Reynolds style hookup installs through the flat plate. I pulled my 18 yd on the ag drawbar for the first season behind a 75C with 3000 lbs of weight in the front. It is as far from desirable as you can get. It may not be quite as bad with a 14 yd, but every bump you hit with a load on you'll feel like your doing a wheelie. Not to mention the balance will be off and you won't get as much traction as you should. I bought my hitch through USA Scrapers in Oklahoma. Very reasonable prices and they sell edges and end bits too.
