It’s revved up and means business.
There’s tough. Then there’s this—the Commercial 21 X-Series—with its front engine guard designed to protect the valve cover and other vital parts from trailer damage. And its formed, steel wear plates on the cutting deck edges to guard against the abrasion wear that comes with the job. If you’re looking for performance and durability in a commercial-grade trim mower, get yourself a Commercial 21 X-Series.
