Zero-turn riding lawn mowers make tight-radius turns around trees and barriers while providing broad cutting widths and fast mowing speeds to cut grass on large lots. They generate more power to cover more ground and cut through thicker or wetter turf than walk-behind mowers. These ride-on mowers trim grass to a uniform height to control weeds and pests and maintain the appearance of yards, grounds, and other green spaces. Their wide wheelbase provides stability on flat terrain without steep slopes, uneven spots, tree stumps, or other obstacles that could cause rollovers.
