PROBLEM TO BE SOLVED: To provide a lawn mower in which the duct portion 26 of a mower device 20 liftably mounted on the lower side of a travel machine frame is covered with an upper cover body 27 having a downward U-shaped cross section from the upper side, and the front end portion of the upper cover body 27 is vertically rotatably connected to the mower device 20, and which prevents conveyance air from leaking from spaces between the right and left side portions of the duct portion 26 and the right and left side portions of the upper cover body 27.
SOLUTION: Mower seal members 100 having L-shaped cross sections and used for closing spaces between the right and left opening edges of the upward opening 26a among the duct portion 26 of the mower device 20 and the right and left side plates 27a of the upper cover body 27 are disposed in a state extended in the longitudinal direction. The mower seal members 100 are made from elastic members such as spring steel, and are always in contact with the insides of the right and left side plates 27a in the upper cover body 27 in spite of the lifted or lowered position of the mower device 20.
