Since it is a 3 pt backhoe, you might get it to fit, but you also might not be happy trying to use it. First, it's a 7 1/2ft hoe meant for a smaller, Cat I tractor, not your Cat II big boy. Your higher ground clearance will mean less digging depth. Don't know how using your Cat II 3 point would work with the Cat I dimensions and mounts on the backhoe. Re-positioning, which is something you do a lot with small backhoes anyways, would be a pain on your big tractor.
If you're really desperate and need a backhoe ASAP for a project, this might get you by, but if you're looking for a useful attachment to have for the long term on your tractor, this ain't it, IMHO. For the one-time project, you'd be better off going down to your rental yard and renting a B26 for a weekend. If I needed to own and use my own backhoe (which I do, actually), I'd be looking at something with a smaller footprint than an M8560 for that kind of work.
I have a M4711 Kabota backhoe attachment that comes with a 12 and 24 inch buckets. Was used to dig about 300 feet of water and sewer line. new the unit sells for over $11,000 asking $6,500. I live in N Texas. It also comes with longer 3 point arms and the subframe. for more information call 907.378.2338.
