They used to run those at our local ski area when I was a kid, except without the cab and not with those tracks. They had the standard narrow tracks, with 2x4's bolted on to widen them.
My neighbor used to groom there then, and "fondly" remembers how close your feet were to the tracks, plus what happened if (when) they got at all sideways on the steeper areas. (FWIW, he still farms in these hills, and he's rolled tractors several times over the years. One tough old bird.)
