We are looking at upgrading combines this off season, currently run a 2004 670 challenger and have been quite happy with it, very few issues over the years. Ran an 8780xp before that. Feel it's time to upgrade machines and headers however. We will be looking at used 9795/9895's and 9540/9560's. Just wondering what kind of updates were done to the 9795 compared to the 9790. I definitely like the design of the 9540/9560 and would prefer to make that jump instead but used availability and price might restrict that as we are on a budget. Wondering if anyone has ran all 3 and could give a good comparison between the 3. Thanks in advance.
