摘要： A mower deck to be mounted on a traveling vehicle is disclosed. The mower deck includes a housing having a top wall, at least one blade rotated downwardly of the top wall and about a vertical shaft, and a blade baffle unit extending downwards from the top wall in such a manner as to surround an outer circumferential area of a rotational path of the blade to create therein a mulching blade rotation space, the blade baffle unit having a front baffle located on an advancing side of the traveling vehicle and a rear baffle located on a reversing side of the traveling vehicle. The front baffle extends downwards from the top wall to exceed the rotational path so as to prevent discharge of cut grass pieces via a lower end of the front baffle. The rear baffle extends downwards from the top wall by such an extent to allow discharge of the cut grass pieces.
