Walk-Behind Lawn Mowers

Commercial 21

Productivity. Commercial Durability. Ease of Use.

Get more work done and get it done right with Exmark commercial walk-behind lawn mowers. Time-tested durability and unparalleled cut-quality come standard on our S-Series and X-Series 21-inch self-propelled mowers. 

Powered by a Kawasaki engine, every 21-inch deck width model is designed with our patented front-wheel height adjustment system. The straightforward design makes conventional pivot-style adjusters obsolete. There are zero grease points and less than half the parts of other walk-behind mowers in its class. That makes servicing our self-propelled mowers as easy as it gets. Then there’s the single-speed transmission, simplified bail system, single-point rear height adjustments, the innovative blade design that makes it easy to go from mulching to bagging. And both models provide variable speed, from 0 to 4.2 mph. The list goes on and on. Just like the mower.
