1. Apparatus for producing parallel-walled seed grooves, said apparatus comprising:

  • a frame;

    rotatable means rotatably supported on said frame, said rotatable means including a shaft and a plurality of disc pairs, said plurality of disc pairs being spacedly securable to said shaft, said shaft extending through said plurality of disc pairs, each said disc pair having first and second opposing and spaced outer peripheral perimeters;

    a plurality of first and second cutting means supported on each said disc pair, said first and second cutting means being arranged in pairs and positioned, respectively, on first and second discs of said disc pair and projecting outward of said perimeters;

    each said first cutting means being positioned on said first perimeter opposite the second cutting means positioned on said second perimeter;

    said pairs of cutting means being positioned such that the area, which is defined between said first and second cutting means and traversed by one pair of cutting means when said rotatable means is rotated, is overlapped by the same defined area of the pair of cutting means following in rotation, whereby continuous and spaced cuts will be formed;

    one respective elongated runner and one respective capping share associated with each said disc pair, said respective runner having a first and second end, said first end being attached to said frame and extending rearward thereof and along an area defined between said continuous cuts associated with said respective disc pair, said capping share being supported at said second end of said respective runner, said capping share including resiliency means for resiliently mounting capping share to bear against said area, and means for varying the resiliency of said resiliency means;

    adjacent ones of said runners having different lengths to allow said capping share to extend in a staggered arrangement behind said apparatus.
