ABSTRACT OF THE DISCLOSURE The specification describes a stump chipping disintegrator wherein stumps are received in a trough having a rotatable chipping disc at one end and a powered ram plate at the other, the ram plate having diagonally extending penetrators. A stump stabilizer anvil adjacent the disc projects radially inwardly of the trough. The disc has steel, wood slicing blades at the radially inner portion thereof, mounted at a small acute angle to the face of the disc toward the direction of rotation, and carbide chopping blades at the radially outer portion thereof, mounted at a large acute angle to the face of the disc toward the direction of rotation. At least the carbide blades are mounted in special holders removable from the disc. The carbide blades have backup wedge elements that extend substantially the width of the blade at its outer end and extend substantially to the radial outer edge of the blade. Wood chips sliced off by the steel blades and chips chopped off by the carbide blades all pass through the disc to be propelled from the apparatus.
