I made a chain link drag. Get an old piece of fence and wrap the front end of it around an old T post or pipe....and wire the ^%$# out of it around it with heavy wire. Get an old heavy hardwood pallet of appropriate size and turn it upside down on top of the fence. Wire this on all the way around, also with heavy wire. This keeps the fence from balling up during use. I then installed an old piece of rusty chain on the front wraped around the t-post/pipe a foot or so from each end, and then made a little loop in the center of the chain to drop over my trailer hitch ball. Drop some BIG rocks into the overturned pallet, and have at it. The weighted pallet keeps the fence fairly flat and helps level what ever you run over with time.... Great thing for dragging trails......
