Abstract
Lawn mower (2) includes a housing (4) having at least one cutting chamber (22 or 24) in which a flexible line cutting element (8) is rotated by a motor (76). Sails (80) located on cutting element (8) are configured to generate an air flow in the cutting chamber (20 or 22). This air flow is directed to a discharge outlet (38) in the housing (4) which causes the cut grass particles to be deposited in a grass collector (14). Grass collector (14) includes air discharge outlets (94) which evacuate the air flow from the grass collector (14) to ensure proper deposition of the grass particles therein. Sails (80) are preferably flexible so as to be incapable of severing a body member accidentally placed into contact therewith. An improved sail (240) radially outboard of a support disc (224) overlies flexible lines (226 and 228) to give better agitation of the vegetation in yet another embodiment.
