John Deere’s latest combine models – the 400hp T670i and C670i plus the 530hp S690i – were on show for the first time.

All are said to offer up to 23% more output than their non-i equivalents. All come fully loaded with high-tech kit, including GPS auto-steer, auto feed rate control and Deere’s Harvest Doc software. A choice of in-cab display systems is also offered.
