Chaffer Lumber Saw
This saw would chaffer out lumber on the tree, to make the tree fall, by cutting a notch in the bottom of the tree to make it fall sideways, while the tree is supported by a crane arm. Then, the crane arm would remove the tree from the stump and lay the tree down on the ground. The saw bits would be removed, and then a box cutter blade, which is four saws that wrap around the tree stone, would cut away any deadwood and any limbs, by running parallel up the tree to the top, after the bottom of the tree trunk is cut from the stump.
