Good JD 643 corn head for sale, usually shredded since we had it.  We used it on IH combine, used our grain head drive shafts so has short hex shafts, no flex shafts are included, also comes with the original JD double chain style shafts.  Outside snouts are John Deere oem poly, right hand rear snout fender has been repaired as mounting nuts pulled out (see pics of round hole in side).  Already have new replacement and will include for extra $200.  Could use rebuilding, but worked fine for us.  Went to 8 row is reason for selling.  Pm or call text 7B5-85I-7OOI with any questions.
