ABSTRACT:
A lawn mower has a power source for rotationally driving an output shaft. A housing has an interior space having a generally spiral-shaped portion. A cutting blade is disposed in the interior space of the housing and is connected to the output shaft for rotation therewith to cut grass while the spiral-shaped portion of the interior space generates a swirling airflow allowing the cut grass to swirl within the interior space. An enclosure is connected to the housing and has a grass discharge passage having an inlet opening disposed in communication with the interior space of the housing for discharging grass cut by the cutting blade and swirling within the interior space of the housing. A guiding member is disposed in the interior space of the housing for gradually changing a direction of the swirling airflow and the swirling cut grass and for guiding the swirling airflow and the swirling cut grass toward the grass discharge passage of the enclosure.
