what kind of header is itIJ We had a MacDon 960 a couple years ago that did basically the same thing and we never did figure out what the problem was but the next fall we got a 962 with the new adaptor that has the feed drum set back behind the header and has retractable fingers and the only time it backfeeds under a side draper is when you are only feeding one side. We love our 962 now and wouldn't run anything different.
