Its hard to tell form the pictures, but I think that head (12 row chopper, folding) is a Harvestec head. CNH must be using these as OEM heads in Europe. Does anybody know for sureIJIJ The knife rolls that are in the North American head are not the greatest. After some acres, the stalks are not chopped, and look like the field was hand picked by a bunch of Menonites. If you want a good working head that really chops stalks look at a late model (04 or newer) Harvestec, thesy do an awesome job and have really good quality parts that last. The early ones were trouble though. The new Deere looks very similar to the Harvestec principle, but I have not seen one work.
