One was a Sabre lawntractor by John Deer. First one I ever saw, was in nice shape getting serviced. Another one was an odd duck for me. Was a Swisher, three wheeled, small deck, engine under the hood, drive was by the single front wheel. To reverse the wheel was turned backwards. Was called a Zero Turn. The owner said he did not knoiw how old it was, looked to be from 10 or 15 years ago perhaps. I watched it mow from a distance, seemed to be doing good. Was a real cool looking little mower.
