In the production process of crop planting, animal husbandry production and related products, the use of related machinery and equipment is inseparable. These machinery and equipment can all belong to the category of agricultural machinery. System, agricultural machinery common classification has 2 kinds:

First of all, according to the power used and its supporting methods: for the walking or moving of agricultural machinery, such as various traction types of mechanical equipment; the other is to play a driving role in equipment, such as tractor drive, electromechanical power drive.

Secondly, according to the operation mode to distinguish, the common classification has walking operation and fixed operation. Depending on the location of the operation, agricultural machinery is divided into field operations, field operations, indoor operations or water operations, road operations and aviation operations and other types.

Small agricultural machinery is divided according to the size of agricultural machinery, in a smaller area of agricultural production, it is more suitable for small machinery, such as small basins, hilly areas, small agricultural machinery has the advantages of flexibility, easy to move and so on. For areas that are not suitable for large agricultural machinery, small agricultural machinery is the palm of farmers. First of all, its cost is relatively low, which can be borne by ordinary farmers; secondly, the maintenance and repair of small agricultural machinery are more convenient, and the cost is also controllable. Moreover, the technical difficulty is relatively low, and many farmers can learn by themselves and are easy to control [1]. Small agricultural machinery has a wide range of applicability and can be widely used in many regions of the country.
