Abstract
A grass cutting blade is provided which can be rotated in either direction while providing cutting and airlift in either direction. This can be used in cooperation with a cutting deck housing which includes a particular discharge opening and channel configuration which facilitates side discharge for one blade direction and mulching in the other. By controlling the blade direction, such as by an electric switch controlling electric blade shaft drive motor, side discharge or mulching can be had at a flip of a switch.
