How are you guys taking OLD hedges out (I mean really old and really rooted)??? I was doing some around my house today, they are probably 45-50 years old. The roots on these things are HUGE and are pretty deep. I tryed using a JD 4200 today but they did not budge. I got a few out by cutting them off at the bottom, digging around the roots and cutting again 6 inches below the soil. It was a PITA. Got any easy methods besides TNT????
