Who uses Toro's 455-D wide area mower? I just purchased one and what a great machine. Tons and tons of power for the thick stuff and can go about anywhere with 4WD. I was cutting 2' tall grass at max speed (6.5 mph) and leaving nothing behind. The unit didn't even slow down with the 55HP Diesel. I was very impressed. It is very quick and maneuverable. I'm going to use this for estates and large commercial properties that are 2+ acres and would like more speed out in the open. The transport gear is 15mph top end which is flying. Anyone ever try mowing in transport or look at changing the gearing for a little more speed?
