With the 9R 640, John Deere presents the strongest articulated truck ever built in Waterloo. We accompanied him during the stubble cultivation. At this point, it’s time to briefly explain the three configurations of the 9 Series: While the 9R is an articulated truck with wheels, the articulated 9RX has four tracks. A special form, on the other hand, is the 9RT as a full caterpillar, which is only available with a maximum of 627 hp. In addition, this design is not very common in Europe because of its width, so we are focusing on the 9R and 9RX here.
