Combines CIH 1666

I bought a 1994 1666 two years ago a an auction and really like it. I've been told that the only real difference in this to the 2166 is the cab and controls. I have an 8 row corn head and a 25' bean head which the combine seems to handle OK.

Do you have field tracker on itIJ if you could would you install it for bean harvestingIJ Thanks Jack
