Where are you locatedIJ Do you like to keep the loss behind the combine really lowIJ I think you will struggle to keep the loss from a 9610 as low as a 2388 when you push them to max capacity. The trick on any walker machine is to keep the grain from ever getting to the walkers. I think some folks get it figured out, but most don't. I have no idea how to set a 9610 up, but find the 88 series very easy to deal with.
