Offering "plug-and-play" convenience via an open architecture approach, the John Deere 750J and 850J crawler dozer models are now available with an Integrated Grade Control option. These machines now can be shipped from the factory with hardware, software and wiring ready to support the grade-control system of the customer's choice. Deere is working under separate development agreements with two of the leading suppliers of grade-control systems to provide this technology for dozers, graders and other machines. The 750J and 850J dozers are the first to be available with this technology for integrated grade control.
