the problem with inserts is you loss capacity,with going to small wire concaves you don't and it takes less then a hour to change concaves for small grains and just use round bar for corn and beans and always make sure the concaves are level.
Those are our new inserts that will be a part of our concave upgrade kits that will be available this fall! If you are interested in pricing on a kit shoot us an email at calmercornheadsmedia.com. Thanks!
