I was looking on MachineFinder.com at the x750 mowers and happened to see a photo of one with the hood open. I thought I saw the flywheel and enlarged the photo. My eyes did not deceive me, it was the flywheel. The engine is mounted backwards from the conventional method of a motorized vehicle. Does anybody know why and how does the thing move? What drives the transmission? Craziest thing that I have seen in quite a while.
