A mulching attachment is provided which is adapted to be detachably secured in place within the cavity defined by the deck of a lawn mower in spaced relation to the mower discharge chute opening, so as to permit air flow thereby and to enable virtually unhampered bagging of the leaves picked up by the mower. The mulching attachment comprises a mulching plate which is disposed above the plane of the path of travel of the mower cutting blade, with a portion of the lower edge of the mulching plate being disposed closely adjacent to the upper surface of the cutting blade during rotation of the cutting blade so as to provide a shearing or scissoring cutting action in the area of the lower edge portion. The radial outermost portion of the lower edge of the mulching plate is shaped so as to permit air flow thereby. In one embodiment, a pair of plates are used to form the mulching plate so as to enable the size of the mulching attachment to be adjusted to accommodate mowers of different types and sizes.

In combination, a lawn mowing machine comprising a cutting blade, a housing for said cutting blade defining a cavity in which said blade rotates and including a discharge chute including a discharge opening through which materials cut by said cutting blade exit from said housing, a plurality of wheels secured to said housing, drive means for causing rotation of said cutting blade within said cavity of said housing; and an imperforate, substantially vertically disposed mulching member secured to said housing within said cavity, in spaced relation to said discharge chute opening, so as to permit air flow thereby, said mulching member being disposed above the plane of the path of travel of said cutting blade and extending generally transverse to the longitudinal axis of the discharge chute so as to guide said materials to an area below the lower edge of the plate, adjacent to the inlet end of the chute and spaced inwardly from the wall of the housing and at least a portion of the lower edge of the mulching member being disposed closely adjacent to the upper surface of the said cutting blade during rotation of the cutting blade so as to cooperate with the rotating blade to provide a shearing or scissoring cutting action in said area.
