ABSTRACT:
A lawn mower of the type which collects grass cuttings includes a motor-driven blade rotatable about a sustantially vertical axis, at least one fan rotatable about the same axis, and a grass collecting system of the type in which grass collection is aided by suction from an airstream produced by the fan. It includes a closure which is selectively adjustable to at least two positions: one in which a grass collection aperture in a grass box is closed and a debris collection aperture in the grass box is open, and the other in which the grass collection aperture is open and the debris collection aperture is closed. A second embodiment includes a closure which is selectively adjustable to at least two positions: one in which both the grass collection aperture and the debris collection aperture are open, and the other in which only the grass collection aperture is open.
