PROBLEM TO BE SOLVED: To provide a mower in which three blades capable of being rotated on vertical shafts, respectively, are arranged laterally in parallel in a deck and which is formed so as to rotate the central blade and one of the lateral side blades in the same direction, rotate the other in the reverse direction, join grasses cut using the central blade and the side blade to the grasses cut using the other side blade and subsequently backward discharge the joined cut grasses from an exit formed at a laterally central site in the rear portion of the deck, capable of efficiently joining right and left grass-carrying winds to discharge the cut grasses. SOLUTION: The inner surface of a deck is formed so that the cross-sectional area of a flowing route Ra of grasses cut using a central blade 15a and one 15b of lateral side blades is larger than that of a flowing route Rb of grasses cut using the other 15c, and a difference is given between both the height of the route Ra and the height of the route Rb at their joining point.
