I have a Drago 8 row cornhead on a 7010 and I am with having trouble with corn backfeeding at the feederhouse. Have the drum raised in high position. The head came with different stops for the feederhouse drum. Drago says it is only necessary to change the stops if using a 12 row head. Is anyone using the drago feederdrum stops with a 8 row head on a 7010?
