  • Patent number: 9200419
    Abstract: A snowblower assembly for removing snow from a paved surface, such as roadways and airport runways. The snowblower assembly includes a snowblower assembly that defines an open interior that encloses a pair of rotating side augers and a rotating impeller. The snowblower housing includes a lower leading edge that is recessed behind the blade tips of the rotating impeller. The sidewalls of the snowblower housing each include a recessed lower sidewall edge to reduce the buildup of snow within the snowblower housing. A side plate extension is mounted to each of the sidewalls to modify the volume of the open interior defined by the snowblower housing to accommodate different types of snow.

  • Publication number: 20120192464
    Abstract: A snowblower for removing snow from a paved surface, such as roadways and airport runways. The snowblower includes a blower assembly having a blower housing that encloses a pair of rotating side augers and a rotating impeller. The blower housing includes an upper hood. The upper hood is angled from a trailing edge to a leading edge such that the angled upper hood provides enhanced visibility of the operator of the snowblower. Each of the side augers is driven by a hydrostatic drive motor that is positioned above the upper hood to remove the drive motors from within the open interior of the blower housing. The drive motors are driven from a power source separate from the power source used to rotate the impeller. The lower, leading edge of the blower housing includes a V-shaped lower edge to further enhance the direction of snow into the blower housing.

  • Publication number: 20050230168
    Abstract: Provided is an all-electric riding greens mower. The mower includes a frame which is supported for movement upon a plurality of ground engaging wheels and upon which are supported a modularly interchangeable power source and a plurality of reel lawn mowers. An electric motor provides driving torque to enable movement of the mower between and over golf course greens or other surfaces to be mowed, electric motors provide driving torque for each of the reel lawn mowers. The interchangeable power source provides electrical energy for driving the electric motors, including the primary mover and the electrical motors for the reel type lawn mowers. The modularly interchangeable power sources may comprise a bank of batteries, a motor/generator set, a fuel cell, or a combination of these. The power source may be easily exchanged in the field for another, freshly charged power source. Exchange occurs using either a fixed change stand or a mobile change stand.
