Abstract
A grass cutting system for use on a walking operator type or a riding type lawn mower as mounted between front and rear wheels. This grass cutting system comprises a cutting blade rotatable on a vertical axis, a grass catcher disposed above the cutting blade and defining a top opening, and a housing surrounding the grass catcher. A cylindrical space is defined between the grass catcher and the housing, through which grass clippings are fed with air currents from the cutting blade to the grass catcher.
