Beauty is in the eye of the beholder but why would someone consider hanging an ugly old barrel an a nice looking tractor?
But if I was going to build a barrel weight, I would consider a cat. 1 draw-bar and poke that through the barrel, and fill with cement. This would be stronger than re-bar as far as bending, and they only cost $20 or so.
Be careful so you don't make the thing to heavy for your tractor. There will be a lot of jerking around back there and you don't want to rip something off the rear end. I never heard of that happening, but I'm new here.
