zeroturn

Zero-turn, commonly written zeroturn, refers to a class of ride-on lawn mowing and turf maintenance machines that can turn in place by varying the speed and direction of two powered drive wheels. This gives the mower a near-zero turning radius, enabling precise work around obstacles and along edges.

Most zeroturn machines use two rear wheels driven by independent hydrostatic transmissions and two front caster wheels for support. By driving the rear wheels at different speeds or in opposite directions, the mower pivots or follows tight arcs. Cutting decks typically mount between the wheels and come in widths from roughly 42 to 60 inches, with options for mulching, side discharge, or rear bagging. Power usually comes from gasoline engines, with some diesel or electric variants; top speeds commonly range from about 6 to 12 mph.

Zeroturn mowers are popular for residential lawns, commercial landscapes, and maintenance tasks that require maneuverability and efficiency. Stand-on versions offer a compact footprint and quick entry/exit, while traditional sit-down models provide stability and longer operation on larger properties. They are used for clearing complex shapes, navigating around beds, and reducing mowing time on irregular lots.

History and market presence: Production of zeroturn mowers began in the mid- to late 20th century and expanded significantly in the 1990s and 2000s as commercial landscapers adopted them. Major manufacturers include Toro, Exmark, John Deere, and Walker.

Safety and limitations: Operation requires care, especially on slopes and uneven terrain, where rollover and turf damage are risks. Maintenance of hydraulic systems and blades adds complexity and cost compared with conventional lawn tractors. Proper training and adherence to safety interlocks are recommended.
