This is the new John Deere Q850M Quicktrac stand-on lawn mower powered by a 27hp Kawasaki, with a 54-inch deck. Our local Midwest Machinery graciously allowed us to take this mower out to a few of our lawn-mowing accounts for a few hours to see how it compared to our 52-inch Toro Grandstand. In this video, you will see the Q850M in action and my thoughts on the new quicktrac.
