Didn't Sukup or someone in Canada sell a rig to catch chaff? Seems I remember one with a trough with an auger behind the shoe and a blower on the end. One thought is that you can get much more MOG over the shoe on a rotary machine, especially in dry brittle crops. I have seen numbers like 50% of the MOG going over the shoe, so you may need a lot more capacity than on a walker machine.
