ABSTRACT:
A mower unit includes a housing, a pair of cutting blades arranged inside the housing, each of the cutting blades being rotatable about a respective vertical axis supported by the housing, the cutting blades being driven to be rotated in opposite directions, and a baffle arranged generally between rotation regions of the cutting blades to guide air flows generated by the cutting blades. The baffle defines an upper baffle portion located adjacent an upper region of the housing, a lower baffle portion located adjacent a lower region of the housing, and an air passage formed for allowing the air flows to flow between the upper baffle portion and lower baffle portion.
