ABSTRACT:
A convertible grass cutting and snow blowing machine which is supported on wheels and displaced on a surface where grass is to be cut or snow removed by a user controlling the machine from a handlebar. An engine is connected to the rotor housing which serves as a chassis, and has a drive shaft which is coupled to a rotor to impart axial rotation to the rotor. The rotor is supported between opposed side walls of a rotor housing, and is provided with at least two cutting blades secured longitudinally and spaced apart. The blades extend at a uniform height from the central axis of the rotor. Each of the blades defines a bow-shaped curve to direct grass cuttings or snow toward a mid-length region of the rotor when the rotor is rotatably driven and further, in combination with the rotor, impart a centrifugal force to direct the grass cuttings rearward toward an exit chute or snow upward toward a snow chute.
