It will be of great advantage. Small seeds, and any crops with a lot of "duff" need more time prior to the chaffer to even out and stabilize. Of course Farmer Ed did'nt say what he's going to do, but I've been working on a variable speed, ribbed belt. The material that falls from the concaves would hit the belt that travels at a pretty good clip, and exit the belt against a pan that shoots the material downward onto the chaffer. In my opinion, the seed_grain then would be suspended, but not entrapped, in the chaff. The chaffer should then be able to start the seperation earlier, rather than spend so much area just shaking the chaff_duff apart.
