The Deere Draper has its integral center frame, to interface with the rest of the draper header. So trying to adapt a Bish adapter to the integrated JD frame _ adapter would get pretty complex. The wider center feed draper would not feed into the "narrow" 21XX feederhouse very well. Rather than trying to adapt to an adapter, I think, it would be better to find an orginal MacDon draper with a center adapter intended for a 21XX. Eventually ASABE _ CHIS Combine Header Interface Standardization would make header attachment and interchangeability much simpler and safer. I request that farmer will support and request CHIS through their ag organizations, dealers and manufacturers.
