The invention discloses a push type grass-combing root-cutting machine which includes a root-cutting machine main body which is formed by a machine casing and a Y355 motor disposed at the top of the root-cutting machine main body. According to the push type grass-combing root-cutting machine, the shortcomings that original products are single in function, cumbersome in use and high in use cost areovercome. The novel push type grass-combing root-cutting machine has the advantages of having more functions and being simple and convenient to use and low in use cost. The push type grass-combing root-cutting machine is provided with a handle and a roller. When the push type grass-combing root-cutting machine is used, a user first switches on a start switch and then pushes the root-cutting machine through the handle and the roller to work, thereby achieving the advantage of simplicity in operation. The advantage of more functions is achieved by arranging a sound-absorbing layer and a dampingpad and the like. The noise and vibration produced by the root-cutting machine during use can be reduced. A battery jar and the Y355 motor are arranged. The product uses electricity as energy, and the user only needs to replace a battery in the battery jar periodically.
