Abstract
A lawn mower includes a cutter blade rotatably disposed in a cutter housing, for cutting grass, a discharge fan rotatably disposed in the cutter housing upwardly of the cutter blade, for discharging grass clippings cut off by the cutter blade, a power source disposed outside of the cutter housing, and a speed reducer mechanism disposed outside of the cutter housing upwardly of the discharge fan, for transmitting mechanical power from the power source at a reduced speed to the discharge fan to rotate the discharge fan at a speed lower than the speed at which the cutter blade rotates. The cutter blade comprises a flat member and lies substantially horizontally.
