The lawn mower cutting implement has an elongated mounting plate adapted for attachment to a lawn mower in lieu of a conventional blade with an end piece attached to opposite ends of the mounting plate. The plate is bent or twisted to generate airflow when the plate is rotated by the lawn mower drive shaft. Each end piece supports at least two cutting elements at different elevations with respect to each other so that there is at least a lower cutting element for cutting grass to a desired height and an upper cutting element for mulching suspended clippings.
