Lawnmowerenginepowered refers to lawn mowers that are powered by an onboard engine, typically an internal combustion engine, to drive the cutting blade and, in many cases, propulsion. In this category, gasoline-powered four-stroke engines are most common for residential mowers, though some earlier or budget models used two-stroke designs. Engine-powered mowers are distinct from manual push mowers and from electric (corded or cordless) mowers, which draw power from an external source or a battery.

Historically, powered lawn mowers emerged in the early 20th century and rapidly displaced manual labor for medium-to-large lawns. Modern engine-powered mowers span compact residential units to larger commercial machines, with engine outputs roughly in the 1–7 horsepower range for consumer models.

Design and operation: An internal combustion engine drives a spindle that spins the mowing blade. Many models offer a self-propelled option, using the engine to power a transmission that moves the wheels. Regular maintenance includes changing the engine oil, cleaning or replacing air filters, checking or replacing spark plugs, and sharpening or replacing blades. Fuel strategy depends on the engine type; four-stroke engines use gasoline with oil in the crankcase, while two-stroke engines require a mixed fuel-oil ratio and more frequent maintenance.

Performance and considerations: Engine-powered mowers provide strong cutting performance and maneuverability over larger areas and in environments without reliable electrical access. They are typically louder and emit exhaust compared with electric counterparts and require more storage, fuel management, and routine maintenance. Safety features and proper handling are essential to prevent injury during operation.
