摘要：
Disclosed is a lawn mower (100), comprising: a rack (110)； a cutting component arranged on the rack (110)； four drive components (120, 122, 124, 126) arranged on the rack (110), each of which is provided with an output shaft (128)； four drive wheels (130, 132, 134, 136) connected with the four output shafts (128) respectively, the circumference of the driving wheels (130, 132, 134 and 136) being provided with a plurality of planet wheels (140), a plane where the rotating direction of the planet wheels (140) is arranged and a plane where the rotating direction of the driving wheels (130, 132, 134, 136) is arranged being positioned in an included angle, and at least part of the peripheral surface of the planet wheels (140) being exposed outside to come into contact with the ground； and a controller connected with the four driving components (120, 122, 124, 126) for independently controlling the four driving components (120, 122, 124, 126) respectively. The described technical solution at least has the following technical effects: the controller independently controls each of four drive components to drive one drive wheel respectively； upon a zero-radius turn, a plurality of planet wheels arranged on the circumference of each drive wheel can rotate on the lawn, thereby reducing slippage of the drive wheel and further reducing the wear of grass between the driving wheel and the lawn so as to mitigate the wear of lawn.La présente invention concerne une tondeuse à gazon (100), comprenant : un bâti (110) ； un composant de coupe placé sur le bâti (110) ； quatre composants d'entraînement (120, 122, 124, 126) placés sur le bâti (110), chacun étant doté d'un arbre de sortie (128) ； quatre roues motrices (130, 132, 134, 136) reliées aux quatre arbres de sortie (128) respectivement, la circonférence des roues motrices (130, 132, 134 et 136) étant dotée d'une pluralité de roues planétaires (140), un plan dans lequel la direction de rotation des roues planétaires (140) est disposé
