How does that 4960 handle that Kinze 1040? We have a Kinze 800 with a 4840 and a full rack of weights and when it's loaded down, it's all it wants. It pushes the front end so you have to use the brakes if you want to turn. An articulated tractor would probably the preferred option.
In the first picture with the combines lined up, you can't tell which one is the 9660 unless you look real close at the unloading auger. That gave it away to me. Now I could be wrong, but the far right one is the 9660.
