steak, I'll give a guesstimate, here in MN a 1660 like you described would maybe be in the range of 35000. The 1020 header maybe 7000 had a customer buy on a consignment auction last fall for 4900, the cornhead if in good shape maybe 8500. What are dealers asking in your areaIJ Does the 1660 have rocktrap, reverser, chopper and Cummins engine(small model numbers on side)
