Ya thats what I am thinking too. I've heard some rumors on some new kind of system John Deere has in the works called a bi-rotor. I was just wondering if someone could tell me something about it.

JD owns the patent of the bi-rotor concept developed by Mark Underwood, but from that to a new combine called 9950 there is difference.
