I'm removing a bunch of stumps with the backhoe and am looking for a quicker way to cut roots around the perimeter of the stumps. My dad has a cutter of some sort he uses with his 8N. It plunges into the ground and cuts as he drives along. I don't think this will work for me since the BX23's are pretty light in comparison. Does anyone make a root shear of some sort which can cut rioots underground? Will a trencher cut through roots like a chainsaw? Alternatively, I'm going to buy an extra bar and blade for my chainsaw, not worry about ruining them, and throw them away when done.
