Mower Unit

A mower unit comprising:

• a housing providing a mowing space inside thereof;
• a pair of cutting blades arranged in the mowing space, each of the cutting blades being rotatable about a respective vertical axis supported by the housing, said pair of cutting blades being driven to be rotated in opposite directions;
• a baffle arranged generally between rotation regions of the pair of cutting blades to guide air flows generated by the pair of cutting blades in the mowing space;
• said baffle including:
• an upper baffle portion located in an upper region of the mowing space, the upper baffle portion having an upper end protruding inward of the mowing space;
• a lower baffle portion located in a lower region of the mowing space;
• a connecting portion for at least partly connecting the upper baffle portion to the lower baffle portion, the connecting portion having a lower end protruding inward of the mowing space, wherein the lower end of the connecting portion protrudes more inward of the mowing space than the upper end of the upper baffle portion,
• wherein the baffle contacts a rear wall of the housing and partitions the rotation region into a first rotation region for one of the pair of cutting blades and second rotation region for the other of the pair of cutting blades in a rear wall region of the mowing space.
