ABSTRACT OF THE DISCLOSURE: This invention is concerned with an apparatus for chopping forest and bog stumps and snags under field conditions so as to render the chopped wood suitable for transportation, wherein the 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 a bottom. This apparatus com- prises a frame defining a chopping space, a generally vertical wall bounding one side of the chopping space and a cavity below the wall and chopping means reciprocably movable back and forth in the space in a direction perpendicular to the vertical wall. The chopping means comprise a generally horizontal main blade, at least two intermediate spaced blades extending downwardly from the main blade and inclined with regard to each other so that the space between the intermediate blades widens in a downwards direction, and a bottom member secured to the blades and extending mainly between the blades and the vertical wall when the chopping means is in a rearward position. The bottom wall moves into the cavity below the vertical wall during forward motion of the chop- ping means. The apparatus according to the invention also comprises means for supporting the chopping means and for effect- ing its reciprocating motion.
