Hey guys i just got a new idea 325 with a 329 super sheller and I was wandering how do you know when its time to get the snapping rolls rebuilt? I found a company that will rebuild them, but I was wandering if it will help with the corn shelling on them and trash going into machine. Last yr when I used my 324 with a 329 super sheller I had corn shelling on the snapping rolls. I just wanted to see if new snapping rolls would help. Usually when I pick an shell corn the corn is between 17% to 20% moisture.
