I'll argue too.  I can steer it with one hand easy. Here is a video for you to watch.  Watch it in HD too.  https://youtu.be/_no5aX3ghPs Does it look like the combine is steering hard the way he is driving it casually?  The 2nd guy riding on the combine told me back in the day when he was running a Massey he actually lost one of the rear wheels but didn't realize it until he came back around on the next pass.
