A shoulder-hanging type grass cutter (10) includes a grass cutter body (100) and a shoulder-hanging strap (5). The grass cutter body (100) comprises a rotation drive section (1) for generating a rotation force； an operation section (2) for performing cutting work by using a cutter (21) that is rotated by receiving the rotation force； a rod section (3) for connecting the rotation drive section (1) to the operation section (2) and for transmitting the rotation force generated by the rotation drive section (1) to the operation section (2)； and a handle (4) secured to the rod section (3). The shoulder-hanging strap (5) is attached to the rod section (3) on the side of the rotation drive section (1) from the gravity center of the grass cutter body (100). The portion (30A) of the rod section (3) on the side of the rotation drive section (1) from the attachment position of the shoulder-hanging strap (5) is curved in one direction. The one direction is downward in the vertical plane (300) including the rod section (3) and the rotation shaft (22) of the cutter (21) in a state in which the grass cutter body (100) is hung on the shoulder so as to be operable.
