1. A rear discharge type mower apparatus comprising: a blade housing having a top plate, a front wall, and at least one side wall; a center support shaft, a first side support shaft, and a second side support shaft, each supported by the blade housing and extending vertically; a rotatable center blade supported by the center support shaft, a rotatable first side blade supported by the first side support shaft, and a rotatable second side blade supported by the second side support shaft; a guide plate unit located rearwardly of the front wall and having a shape extending along rotation paths of the blades, the guide plate unit including: an auxiliary plate extending from the rear end portion of the first center guide plate portion into the rotation path of the center blade, and having a surface for deflecting rearwardly a part of cut grass moved by a rotation of the center blade, wherein a lower edge of the auxiliary plate is closer to the top plate than the center blade, and wherein the auxiliary plate contacts the rear end portion of the first center guide plate portion and extends substantially straight from the rear end portion toward an inside of the rotation path of the center blade at a predetermined inclined angle, thereby allowing cut grass blown and guided by the guide plate unit along the rotating direction of the blade to be deviated toward a mown grass discharge port formed rearwardly of the blade housing, wherein a lower edge of a front end portion of the first center guide plate portion and a lower edge of a front end portion of the second center guide plate portion are closer to the top plate than a lower edge of the front guide plate.
