If you've ever operated a combine, you'll be well aware of how many factors can influence its performance. Which is why John Deere asked profi to come to an estate near the Baltic Sea on August 8th to document the throughput, grain quality and losses of its new X9 1100 rotary combine as well as a T670i six-walker machine. And when Deere staff said ‘a long day’ they weren't joking; they meant the full 24 hours, as long as Mother Nature played ball.
