1. Helps to increase agricultural productivity

In some areas, the farmland area is small, the terrain is not flat, and large-scale agricultural machinery is difficult to play a role, which seriously hinders the development of rural economy. Small machinery came into being, according to the terrain characteristics of the regional farmland, selective use, so as to achieve agricultural mechanization, improve production efficiency, and promote the construction of a new socialist countryside. We must attach importance to the promotion of small-scale agricultural machinery, deepen the use of various agricultural machinery in rural production activities, improve rural productivity, and create greater economic benefits.

2, beneficial to farmers to generate income to improve economic income.

At present, in many rural areas, the farming methods used in production activities are still very traditional and extremely inefficient. Most farmers cannot make ends meet, which greatly hinders the development of the rural economy and further widens the gap between urban and rural areas. Coupled with the rapid development of urbanization, many farmers go to work in cities, and the number of farmers engaged in farming is gradually decreasing, resulting in the lack of seasonal labor force, resulting in a large number of barren fields and serious waste of resources. The small mechanization is to ensure the inevitable choice of agricultural production, the use of small agricultural machinery in uneven land work, greatly ease the burden of farmers, improve productivity at the same time can also increase the added value of agricultural products, thereby increasing the income of farmers, help to gradually promote the development of the national agricultural production level to a new height [2].

3, is conducive to the ecological development of agricultural economy

In traditional agricultural production, extensive production leads to a series of ecological and environmental problems. The abuse of pesticides leads to the pollution of farmland; the uncontrolled felling of trees causes soil erosion and even geological disasters; the random discharge of all kinds of aquaculture garbage or production waste causes serious water and soil pollution. How to ensure the sustainable development of agriculture while managing the environment, the role of small agricultural machinery can be seen.

The use of mechanization for agricultural production can effectively avoid the occurrence of pollution. With the help of modern science and technology, the traditional mode of production has been greatly improved, thus realizing the sustainable development of agriculture. At present, the area of rural arable land has basically reached the limit value, especially in the context of returning farmland to forests and urbanization construction, the cultivated area of rural land has a decreasing trend. In order to increase production, we should not only select fine varieties for cultivation, but also use machinery and equipment to improve production efficiency, so as to ensure low emission and high efficiency of rural agricultural production and realize the ecological development of agricultural economy.
