  • Patent number: 6658830
    Abstract: A self-propelled mower and vacuum has a front-mounted flail blade mower assembly. After being cut, the grass clippings are propelled through a discharge chute into a cuttings basket by air pressure created by the flail blades and vanes attached to the blade rotor. Additional suction may be provided by a blower system which blows air into the discharge chute. The width of the flale blade mower assembly and the large volume of cuttings which may be held in the cuttings basket make the disclosed device particularly beneficial for mowing large areas of grass and turf, including athletic fields, belt ways and airstrips.
