We have experienced the same shelling in front of the feeder house also. We had a Geringhoff Northstar before trading for the RotaDisc Elite series and did not have near the shelling issues. We compared against the competitors heads this past fall of 2012 and it was a little embarrassing. We are currently trading planters and considering strongly going to 20" rows so will be trading corn heads. Really like the RotaDisc except for the head shelling issues. This is on a CIH 8230 combine. Our other combine is a New Holland 9065 and had similar issues. Would like some input before we trade heads to see if this can be resolved.
Also, is there any concerns going to 20" rows we should be aware of?
