"Runner that is pretty much exactly what I want. Do you have a total project cost?"
Been awhile, but I think I got the HF quick hitch for about $70. The two pieces of channel iron were expensive, like $30 each. Seems like the JD pins and hooks were about $20 total (someone who's bought some recently can probably verify that). I'd say you could be into one for a couple of hundred.
I think if I was doing it again, I'd pop for the JD iMatch to use for the hitch because I think it's make better and the tolerances seem to work better with all my Frontier stuff.
From the beating a backhoe seems to give my tractor, I'd be leery about trying to use one mounted on the loader. Of course, my tractor will just barely lift the backhoe with the loader, so the question would probably academic with a 2520.
Maybe if it had a platform that would allow it to sit completely on the ground while in use? I still think it wuold be hard on the backhoe mounts.
