[0002] With the development of society, the living standards of residents are constantly improving, and the requirements for environmental conditions are getting higher and higher. The area of ​​lawn use is growing rapidly. Whether it is municipal, residential areas, football fields, golf courses, etc., the workload of lawn maintenance has also increased accordingly. Currently, the more common lawn trimming equipment is the lawn mower.

[0003] The existing reel-type mower includes a frame and a reel, which is connected to the running wheel by transmission, and a supporting mobile roller is arranged at the rear of the frame. During the mowing process, the mower is pushed forward by manpower, and the running wheel on the mower rotates and drives the reel to rotate, and the reel cuts the weeds caught in the mower. However, this reel-type mower can only mow grass by pushing the mower forward manually, which requires a lot of labor and has low mowing efficiency. There are reel-type mowers on the market that obtain power by burning gasoline, but the mowers make a lot of noise when working, which affects the lives of the surrounding residents, and have high energy consumption, and the waste gas generated is easy to pollute the environment.
