I need your ideas please

I would use the boxblade with rippers also, because you have it, and it will work. You won't get it done in one pass, but spending money on another implement or rent isn't worth the little extra time it takes to make a couple of passes. Plus a set of rippers is about the cheapest thing to fix if you break something on a LARGE hidden rock.

Ditto what others have said... Don't waste any of your time and effort and go rent a skid steer with a rockhound attachment. You won't be sorry.
