Did some research today and found the guideline for rasp bars is about the thickness of a pencil or 1/4". That's about where mine are. Obviously on this small of a machine I'm not tending huge acreage, so what is the downside to running with rasp bars worn to the point they should be changed? Can they cause an increase in cracked grain? Would they also cause milo stems to be broken up bad and wind up in the grain tank (assuming everything else is adjusted as best as possible)
