ABSTRACT:
A bagging filament line lawn mower (2) has a filament line cutting element (8). A fan (60) located in a cutting chamber (26) in the housing (4) of mower (2) is shielded by an outer shroud wall (68). Shroud wall (68) and fan (60) are configured to create an airflow in the cutting chamber (26) over that portion of the grass traversed by the free end portion (47) of the cutting element (8). This airflow has both vertical and circumferential components to both lift the grass for more efficient cutting by the cutting element (8) and to transport the cut grass particles through the lawn mower housing (4) to a discharge outlet (34). Shroud wall (68) is sufficiently high and is spaced so that an operator during normal operation of mower (2) cannot interpose a body member into the fan path.
