Abstract
Mower unit mountable to a traveling vehicle body and being configured to suppress generation of turbulence. The mower includes a mower deck, a plurality of blades, a rear vacuum plate that includes a plurality of arcuate portions and a convexly curved portion curved to extend into a triangular gap portion formed between two adjacent rotational locus circles. The convex curved portion bridges opposed ends of two adjacent arcuate portions at two inflection points (IP) of the rear vacuum plate. The triangular gap is defined by a distance (S) between the two inflection points (IP) and a top point (TP) located at a distance (L) from a reference straight line connecting center points of the two adjacent rotational locus circles.
