Honda commercial and premium residential walk-behind mowers are powered by easy-starting, reliable, and quiet engines that meet industrial specifications and are 50-state certified to meet EPA and CARB emission levels. These engines are perfectly matched, with power in reserve, for the demanding mowing conditions that you may encounter and allow for mulching or bagging without changing blades. Honda's patented Roto-Stop system allows you to start and stop the mower blades with the engine still running. Roto-Stop lets you empty the bag or move objects out of the way without having to stop and restart the mower. Honda's exclusive MicroCut twin blade system uses four cutting surfaces that result in ultra fine clippings for superior mulching and bagging. Tiny clippings decompose faster and fertilize your lawn. And because finer clippings take up less volume when bagging, you can now mow between 40 to 50% farther before having to empty the bag.
