A machine for coring stumps includes an area for receiving a tree stump that has been removed from the ground. Positioned above this area is an X-shaped wedge concentric with a cylindrical saw, having an annular saw blade. The wedge is dropped into engagement with the stump to aid in holding it steady. The saw is then rotated at cutting speed while being driven downwardly through the stump to remove a core therefrom, leaving only salvageable dirt and loose roots, and debris capable of being easily disposed of. The cylindrical saw is then retracted and the wedge is now driven downwardly through the core to split the core into four logs of quadrantal cross section, providing logs of so-called "fireplace length".
