- Model 21 S-Series - Commercial Lawn Mowers



Exmark Commercial 21 walk-behind mowers offer time-tested versatility and durability, with a cutting system that delivers an unmatched quality of cut. The simple, reliable design features innovations such as patented front height adjusters and single point rear height adjust. A standard multi-purpose blade makes the switch from bagging to mulching easy, so you can give your customers exactly what they want – perfectly manicured green spaces.

They say simplicity is the basis of great engineering. And it doesn’t get much simpler than the Exmark® Commercial 21 S-Series, beginning with its patented front height adjustment. This straightforward design makes conventional pivot-style adjusters obsolete. There are zero grease points and less than half the parts of other mowers in its class. That makes servicing the S-Series almost as easy as it gets. Then there’s the single-speed transmission, simplified bail system, single-point rear height adjust, the innovative blade design that makes it easy to go from mulching to bagging the list goes on and on. Just like the mower.
