This design, hand thrust lawnmowers mainly use the scroll wheel drive mechanical motion. Hand thrust lawnmowers has simple structure, low noise, smooth operation, and very easy to use, bring convenience to people around, comfortable and quiet environment. To better meet the needs of the client. Based on the mechanical design and relevant theory research and design, hand thrust lawnmowers transmission part, and the design method of CAM and putting the end gear and dial design. The design of the hand thrust about lawnmowers, its characteristic is the symmetry of simple structure, smooth operation, small bending, friction, good performance, do not appear to jam, strong adaptability.
