- Model 21 S-Series (ECSKA21) - Commercial Walk Behind Mower


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.
