PROBLEM TO BE SOLVED: To provide a lawn mower preventing the deposition of dust to a part near a rotation confirmation window by removing the dust from the part near the window, enabling clear confirmation of the rotation of a rotary disk and ensuring the safety. SOLUTION: The lawn mower has a wind duct 2 in the main body 1 of the mower and is provided with a disk-shaped grass-collecting fan 3 rotatably attached to the bottom of the body 1 and a grass-cutting blade 4 rotating together with the grass-collecting fan 3 and placed under the fan 3. The mowed grass is collected by the rotation of the grass-collecting fan 3 through the wind duct 2. The mower is further provided with a rotary disk 5 rotating together with and reverse to the grass-collecting fan 3, a rotation confirmation window 6 to observe the rotary disk 5 from outside to confirm the rotation of the rotary disk 5, and a dust-removing fan 7 to send air flow from a part near the rotation confirmation window 6 together with the grass-collection flow of the collection fan 3 for removing the dust and preventing the deposition of dust on the rotation confirmation window 6 or thereabout.
