Abstract: A deck for mowers including an upper and lower decks with structured frame members in between. Both upper and lower decks attach to front and rear cross members at substantially the same point. Upper deck at sides slopes down and is formed with smooth radius; lower deck attaches to bottom side of upper deck just inside of smooth radius. The upper deck is crowned or elevated so that it slopes downward in all directions—front, rear, and sides. The top deck is shaped so that debris and water will divert or fall off the deck.
