Walk Behind


They say simplicity is the basis of great engineering. And it doesn’t get much simpler than the Exmark Commercial 21 S-Series self-propelled lawnmower, 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 walk-behind 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, and the variable speed, from 0 to 4.2 mph. The list goes on and on. Just like the mower.

Commercial 21 S-Series Features

The Exmark Signature Cut

The cutting deck is a full five inches deep, delivering a consistently great cut whether you’re bagging or mulching grass clippings.

Variable-Speed Transmission

Just engage and go, at infinitely variable speeds up to 4.2 mph. Its simple operation makes the S-Series a great mower for training new employees.

Easy On/Off Bag Design
