They do a good job, just takes lots of horsepower. The 50 series did not have a heavy enough drive on the feeder house to run a 12 row. I saw one run on a lEXION 485 at Farm Progress show in 2002. You would get them from a Gerringhoff Dealer. At the Show, I was told Ziegler Cat was the dealer. They are pricey, but you are buying a high quality head. Next best chopping head is the CAT - My opinion.
