Designed to raise the bar for stand-on mower performance and productivity, Vertex X-Series uses the same formed and welded tubular steel frame and heavy-duty 15-inch casters as our premier Lazer Z zero-turn riding mowers. With carbureted Kawasaki FX1000 engines, you’ll have the power to finish jobs faster, with a better quality of cut thanks to our unmatched UltraCut cutting decks. One look and it’s easy to see why the Vertex X-Series is the next generation of stand-on mowers.
