A push mower comprises a mower main body, at least one arm extending upward toward a rear side from the mower main body, and a grip located at a tip end of the at least one arm. Each end of the grip is located on one plane side of an arm plane, a center of the grip is located on an opposite plane side of the arm plane, and therefore the grip extends so as to intersect with the arm plane. Here, the arm plane means a virtual plane on which the at least one arm is located and that is parallel to a left-to-right direction of the mower main body.
