I think you can't go wrong with the CX 840 as a combine. The self leveling grain pain is a reall plus to the machine. You will notice it cycle on headland turns. This means more grain in the hopper and in the bin. We demoed both the CR 970 and the CR 960 last fall and it went very well. Come view the demoes on our web site... ( www.johnbob.ca ) go to the " Follow the CR Combine" view both pic's or video links. I know your talking CX.....But,CR is very similar for features. Enjoy. Your friends @ John Bob.
