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.

Abstract: A monorail vehicle support system for supporting a vehicle body along a monobeam rail having top and side running surfaces. An attachment frame is secured to opposed ends of the vehicle chassis. A single steerable load carrying wheel is supported in a vertical plane by the attachment frame for support engagement with the top running surface of the rail. A pair of side wheels, having pneumatic tires, are supported spaced-apart in parallel horizontal planes below the carrying wheel and on one side thereof for frictional engagement with one of the side running surfaces of the rail. A load arm secured at one end to an axle of the carrying wheel is provided with an air bag and a levelling system for maintaining the vehicle chassis at a substantially constant level with respect to the beam by compensating for vertical displacement of the pneumatic suspension element (airbag) caused by the load variations.
