Starts easily. Runs quietly. And has plenty of power. This 21" Troy-Bilt lawnmower is powered by a 160cc Honda OHC engine. Features the Tri-Action cutting system for a more consistent cut/mulch. Beyond-the-wheels mowing cuts right up to fence, so you won't have to trim the edges anymore. Ergonomic handle adjusts to 3 heights. And you can choose to mulch, side discharge or rear bag.
