This subject always seems to pop up in various treads. Someone will say that Brand A will "mow" faster than Brand B because Brand A can go 15 mph. The question here is: Do you "mow" at the maximum mph rating of your mower? On what type of properties? How often? The key aspect here is "quality of cut" while mowing at XX mph. Is the Manufacturers claim legitmate or is it just marketing hype? My thoughts are that very few LCOs actually mow at double digits mph. Sure they might be able go all out on some commercial outlots (if the ground isn't to rough). They also could utilize the max speed to get from the trailer to the back yard quicker maybe. But if quality of cut is the measuring stick, then I doubt that Brand A can actually "mow" faster than Brand B.
