ABSTRACT:
Apparatus for use in economically profitable chopping of forest and bog stumps and of snags into transportable form in field conditions during all seasons. Chopping is effected by applying pressure which breaks the wood material charge that has been brought in one way or another into the space defined by a main blade and intermediate blades and by a backing plane and bottom. The stumps and snags in arbitrary positions are placed in such position with reference to the blades in connection with the pressing motion that the part of the wood material charge that has been cut off by the blades is able to evade the wedging pressure exerted by the sides of the blades, by sliding into a space which is more free, suffering rupture in the direction of the grain and being urged in chopped condition through the part constituted by the blades into the opening space.
