If the tree can be managed by hand this method tends to work. Cut three sides of a square around the roots. Make it as big a square as you (and your friends) can manage. Leave it a month or two for the tree to get over the shock of having some of it's roots cut, then cut the other side of the square and underneath the roots. It's best done during the winter when the tree is in shutdown mode other than full bloom.
