Abstract
A lawnmower deck includes a deck sub-assembly and a stiffener. The deck sub-assembly has a top surface, a skirt extending outwardly and downwardly from the top surface and encircling the top surface and a first stiffness. The skirt defines a cutting chamber underneath the top surface and a plurality of wheel mounts. The stiffener is connected to at least one of the top surface and the skirt. The stiffener and the deck sub-assembly together have a combined stiffness that is at least approximately 20% greater than the first stiffness.
