With the continuous advancement of agricultural modernization, rotary tillers are also constantly developing and improving. In the future, rotary tillers will develop towards wide width high-speed types and joint operation units. The wide width high-speed rotary tiller will adapt to the demand for intensive and large-scale production of rice, improving cultivation efficiency and quality. The joint operation unit can achieve the integration of multiple functions, reduce operation links and costs, and improve agricultural production efficiency.

Rotary tillers are mainly divided into three types according to the configuration of their rotary blade shafts: horizontal axis, vertical axis, and inclined axis. Among them, the horizontal rotary tiller is the most widely used due to its strong soil crushing ability. With one operation, the soil can be finely divided, the soil and fertilizer can be evenly mixed, and the ground can be leveled, meeting the requirements for sowing in dry land or planting in paddy fields. However, the horizontal rotary tiller has poor coverage ability for residues and weeds, shallow tillage depth (12-16 cm for dry tillage and 14-18 cm for water tillage), and high energy consumption.
