- 19 - GRAIN SAVER ATTACHMENT FOR THE STRAW WALKER OF A COMBINE ABSTRACT OF THE DISCLOSURE In a conventional combine harvester which includes straw walkers which move in an orbital path so as to lift and move straw rearwardly along the straw walkers there is provided an improved attachment device including a surface which is inclined from a front edge upwardly and rearwardly to a rear edge at a position elevated above the saw-toothed side edge of the straw walker and at least one supplementary saw-toothed element positioned at the surface and having a saw-toothed upper edge for lifting straw over the surface and along the remainder of the straw walker. The attachment improves the separation action of the straw walkers and causes more grain to escape from the straw at the attachment with the grain then sliding downwardly and forwardly from the surface through perforations in the straw walker for collection on the conventional shoe.
