Highway hedges need seasonal and periodic trimming and the trimming work is labor-intensive and dangerous. In order to improve the trimming efficiency and ensure the operation safety, a self-propelled hedge trimmer was proposed in this paper, which had the functions of walking and trimming along the central isolation belt in highway. The mechanical structure design and control system design was introduced, and modularized structure was adopted in the design of control system. During the automatic control process, the sensors could collect the environment information in real time, and further determine whether each mechanism worked or not. The proposed self-propelled hedge trimmer is especially suitable for the trimming work in highway, and it can satisfy the requirements in the trimming work.
