While conducting the X9 combine performance test, Deere also opted to bring along its largest walker machine, a T670i, to the Groß Walmstorf estate ... to show what it could do. As for the rotary machine, the Deere test team had opened up two fields the day before and fine-tuned the combine’s settings. The conditions (see ‘The conditions’) were very similar to those the X9 was experiencing, the main difference being the wheat variety — Depot (instead of Reform) from RAGT.
