Abstract: Mowing mechanism for lawn mower with a housing (10) and at least one motor driven blade disc provided in the housing (18, 20), on which cutting blades (20, 24) are secured. Pairs of each other opposing cutting blades (20, 24) extend outwardly from the blade disk and parallel to them, wherein each pair is comprised of an upper blade (22) and a lower blade (24). The cutting blades (22, 24) can exhibit shovel like bent edges (32) for achieving a ventilator effect. When desired two identical blade disks (18, 20) can be provided to each other in the housing, wherein the areas of coverage of the respective blades (22, 24) overlap with each other.
