ABSTRACT:
A machine for harvesting and cutting into sections ligneous stems which grow upwardly from cultivated copses includes a frame which mounts an inverted trough for bending the upper portions of the stems to almost an almost horizontal orientation as the frame moves forwardly; a saw for cutting the bent stems near their bases; a counter blade which provides a plurality of guide funnels that are generally vertically oriented and which have upper outlet orifices with sharp edges; a curved guide element along which the cut stems can move and gather into bundles for movement to and through respective guide funnels of the counter blade; a rotating drum for moving the cut stems along the guide element; and a drum with peripheral blades which pass over the outlet orifices of the guide funnels in the counter blade to cut the bundles of stems passing through the outlet orifices into sections.
