mostly 4ft oaks and cedars,I have a friend that if he has time give me a good deal but like last year I didn't get to use him but moving cedars up to 8ft and 4 inch fruit trees I don't think we have lost one.His spade is a 40 I believe and I got a guy that was between jobs because of the rain come in and moved some large oaks that had been planted 10 years ago,8000 lb root balls.I think 1 may not have made it.We pack the root balls down and water really good and keep watered the first year.
