I used the Schaffert Rebounders and Totally Tubular fertilizer tubes on my JD planter for the 07 and 08 growning season. The results were perfect. There was no seed drag what so ever.
For the 09 growing season I made the mistake of replacing my Rebounders for a set of another brand. The results were terrible. I had seed being bunched up and piled by the other brand attachment. For the 2010 planting season I have purchased a set of Rebounder Seed Covers with Y-Not Split and bullet check valves.
