The invention provides a lawn cutting device utilizing high-tech, lightweight bicycle parts, low-friction bearing assemblies, air-filled bicycle-type tires and a double-overdrive gearing system. The device has a body portion, handlebar, a blade assembly, and a variety of combination of wheel gears, gear rings, and chains, which result in a device which a blade assembly which moves at extremely rapid speeds, powered by the rotation of the wheels. Because of its reliance on low-friction bearings, a minimal amount of force exerted on the wheels is transformed in an extremely efficient manner into the rotation of the blade assembly, resulting in an environmentally friendly, energy efficient cutting device that avoids the pollution, inefficiency, and strain associated with traditional gas, electric, and human-powered lawnmowers.
