Abstract
A lawnmower deck of inverted dish shape having three generally circular, laterally spaced but interconnected open-bottomed compartments in each of which is mounted a horizontally extending blade rotatable on a vertical axis and operable to impel cuttings from one compartment to the next toward one side of the deck, the deck having an outlet opening at that side and at the rearward portion of at least certain of the compartments, there being controllable gates at each of the outlet openings and between each successive pair of compartments, to the end that by opening or closing the gates in the proper combinations, the cuttings may be selectively discharged to the side or to a grass collector, or discharged to the rear, or finely mulched for rapid decomposition to enrich the soil.
