Abstract

A mower blade suitable for bagging, side discharge and mulching is provided. A laterally upswept outboard cutting portion cuts the grass and sucks the clippings upwardly. The clippings are forced by the combined effects of the upswept outboard cutting portion and an upswept inboard cutting portion into an intermediate cutting portion where they are further comminuted and are then sucked back into both the outboard cutting portion and the inboard cutting portion. These double circulation paths result in excellent comminution and superior hiding of the clippings.
