I was successful with the round bar concave and yes, I have ran edible beans, among a few other crops with a lexion. The round bar is ideal for delicate food grade crops, but if you are wanting a more universal concave then try either the N7_18 small grains main concave or the N18 universal main concave. Both have operated well in edible beans, it all depends on the conditions you are in as to which one does the better job. I like the round bar myself and it doesn't take as long as you might think the change the main concave. We change ours out by taking off the feederhouse and take it right out the front, under the APS. Once you have done it once, three of us can do it in less than 3 hours now. I don't mind 3 hours when I can get that good of a grain sample.
