2039155 9102449 PCTABS00003 An air-floated apparatus, such as a lawn mower, is comprised of an endless housing (12) having a bottom opening defined by a relatively flat plate member (42) projecting inwardly from around substantially the entire bottom part of the housing (12). At least one air impeller (14) is provided for pressurizing air within the housing (12) sufficient to float the housing above a support surface. The plate member (42) directs air laterally into the housing (12) to inhibit the escape of air from the housing (12) and maintain a relatively constant pressure in the housing (12). The rotary action of the lawn mower cutting blade (16) centrifuges grass cuttings within the housing. The plate member (42) acts as a shelf to support the centrifuged grass cuttings and cooperates with an inner wall (38) of the housing (12) to direct the grass cuttings into a discharge duct (30) for collection in a bag or other receptacle.
