We have taken the pro700 out of our combine and installed in our JD 8130 to run accuguide. We will be using the tractor for tillage and drilling soybeans with our 20 ft john deere 750 drill. What is the best way to map soybean varieties as we plant? Can the variety tracking software be installed so that we can overlay the maps when we combine next fall? We have a JD Computertrak 350 monitor on the drill. The CIH dealer says that we can buy an implement switch so the Pro700 will know when the drill is down.
