This application discloses a push lawnmower, including a body, a leveling component, a body height adjustment component, a shift plate, a front wheel assembly, a rear wheel assembly, and a cutting component. The rear wheel assembly includes a rotating shaft and a pair of rear wheels. The two ends of the rotating shaft are connected to the rear wheels. The rotating shaft is connected to the body through two assembly points. The line connecting the two assembly points forms a first axis, and the straight line connecting the centers of the pair of rear wheels forms a second axis. The first axis and the second axis are not coaxial. The body height adjustment component drives the rear wheels to rotate around the first axis. The shift plate includes a main body and a support body. The main body is connected to the body, and the support body is provided with a leveling component for direct contact with the ground. When the body is upright, the rear wheels are tangent to the ground. In each position of the body height adjustment component, the angle β between the straight lines L formed by the contact points between the leveling component and the ground and the contact points between the rear wheels and the ground is an acute angle. This application solves the problem of poor standing stability of lawnmowers in the prior art.
