I have a Bish Case IH Header adapter to John Deere. I bought it used from Bish about 5 years ago when they built a all row crop head for me. I had an 853A row crop on for cutting milo, soybeans etc which work excellenct for milo sorghum by the way. They go on easy and are easy to use. I think they are around $1400 new. $450. Good condition. Retired from farming. I dont access this site often suggest you text me at 970-218-9724 I dont have phone signal at the farm but can text
