摘要： A mower unit includes a blade housing, and a guide plate for dividing a grass clipping flow space formed in the blade housing, along a flowing direction into a first flow space and a second flow space communicating with each other in a downstream position with respect to the flowing direction. The blade housing has a discharge section for discharging grass clippings cut by cutting blades, in a predetermined direction along with air flows. The discharge section has an intake opening for drawing ambient air into the second flow space. The guide plate may be displaceable relative to the blade housing to vary a sectional passage area of the first flow space.
