Well CATMANDONT I thought you knew more about CASE COMBINES than you actually do. To start with case has 1 roter, bigger clean grain, differant fan, differant return, differant feeder drive shaft to run the head, I could go on and on. But whats the use to explain it to you, you sound pretty color blind. Just think of red when you go in to spend all that green to rebuild your insides after a 1000 hrs. And you just are not happy unless you are smarting off. So go back to your Deer or Cat page for you really do not know nothing about combines.
