I don't know about beans but it works very well in wheat on an N7. I bought it as a kit new from the dealer. It is not the most easy thing in the world to install. Translation- a real bear. However, it paid for itself. If and when it wears out I'm going to buy a new combine. Translation- I'm not tearing that rascal apart like that again! Don't buy used. Do it right once. My two cents.
