What is the best way to remove full grown tree stumps/roots? I would like to remove some large trees in the yard at my parents house and replace them with pines. This is in the yard area. Is a backhoe the best/only way to get the roots out, or can we just grind the stump and use a large spade to put pines in thier place? The ground is some shitty clay... It would be nice to put some good soil in before the new trees. If we must have a hoe remove the roots, could I rent a mini for a day ($200) and do 8 Elms in one day(8 machine hours), or would I be better off getting a full size with operator to come in? Thanks!
