The invention relates to a lawn mower with front-loaded manually-locked universal wheels. Two positioning pins (17) are arranged on a lock body (16), the ends of the positioning pins are sharp, so that the positioning pins can be convenient to position to a lock knob (11); a climbing surface (16a) from low to high is arranged on the lock body (16), so that the climbing surface (16a) is in contactwith the edge of a circumferential opening in the lower part of a lock nut (13); a lock rod (15) penetrates through a universal upper cover (2) and a universal lower cover (3); an arc-shaped lock headis arranged at the lower end of the lock rod (15); and a lock pit (4a) is arranged in a universal independent oblique arm (4). When the lock knob (11) is artificially twisted for 180 degrees to be locked, the arc-shaped lock head at the lower end of the lock rod (15) is inserted in the lock pit (4a) formed in the universal independent oblique arm (4). A reliable mechanism provides reliable locking, so that the lawn mower having front-loaded manually-locked universal wheels successfully achieves linear motion and can be exported.
