A mulching baffle for providing at least part of boundary walls of a plurality of mulching chambers is detachably attached to the interior of the mower deck. A vertical guide wall constituting the mulching baffle has an inclined surface. A terminal end guide surface is formed in a terminal end portion of the vertical guide wall with respect to a direction of rotation of the rotary blade in a region around an opening for allowing the adjacent mulching chambers to communicate with each other, whereby grass clippings are deflected inwardly of the mulching chamber with which the terminal end guide surface is associated.
