To all, don't underestimate the Challenger combine. This design has silently been awing people for years. With the improvements in the new design, a 660 will compete very well with the 2388s, 9650s, R65s, etc. in class 6. As for the 670, it's a solid class 7 and will be impressive against the 9750s, CNH class 7s, and even lexion 470. This is a combine that is extremely easy to run, set, and operate across a wide variety of crops and conditions with amazing grain quality. Fewer parts and components directly correlates to greater simplicity and grain quality. The lexion is impressive, particularly in its ability to perform both in Europe and here; the Challenger is a North American combine, and one which should prove itself quite well among all competitive brand owners.
