Abstract of the Disclosure A lawn mower has a main frame mounted on four wheels and a horizontal rotary frame rotatably mounted within and to said main frame. A ring with a cylindrical, vertical inner surface is rigidly connected to said main frame above said rotary frame. Three pairs of rotary blades are pivotably attached to the rotary frame by three L - shaped mounts. A motor is rigidly mounted to the top of the main frame to rotate said rotary frame. A rotatable roller is provided to rotate each pair of blades, each roller contacting said surface of said ring when the rotary frame is rotated due to centrifugal force acting on the roller. The roller is rotated when contacting the ring and thereby rotates its respective pair of blades.
