Just as a side bar, were it me, and I have no idea how much you plan on cutting, I would walk with the chain saw and whack them 2 inched buggers down, cause you might find those 2 inch buggers a tad bigger than you think. Also I don't know what size tractor you have but if you have a FEL or a BH, and a couple chains you might be a lot farther ahead getting the root ball out and never having to worry about it again,, Like said a 2 inch hunk of wood can cause a lot of damage really quickly,, just MHO
