Depends how big a digger you get and how big the roots are. A micro digger will get those out, just may be a bit of a pain of digging round them and trying to either cut them or get the teeth underneath and pull. Get the biggest digger you can fit, the bigger it is the more stable it is, I have driven everything from 0.7 tonne up to 20 tonne, and the 0.7s are the easiest to go wrong in!
