Small cultivators are an indispensable part of modern agricultural machinery, characterized by their lightweight, flexibility, high efficiency, energy saving, multifunctionality, strong adaptability, and easy maintenance. In the future development, small tillage machines will continue to play an important role, providing strong support for the modernization and efficiency of agricultural production.

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.

The working speed of rotary tiller should be moderate, with a suitable speed of 2-3 kilometers per hour for dry fields and 5-7 kilometers per hour for already plowed or raked land. When cultivating in paddy fields, the speed can be increased appropriately, but it should not be too high to prevent the tractor from overloading and damaging the power output shaft.

The advantages of rotary tiller are obvious. Firstly, it has strong soil crushing ability and can complete multiple tasks such as plowing, raking, and leveling in one go, improving work efficiency. Secondly, after rotary tillage, the soil is finely divided, the soil fertilizer is evenly mixed, and the surface is flat, which is conducive to sowing or transplanting. In addition, the rotary tiller has a wide adaptability range to soil moisture, reducing the phenomenon of tractor wheel slip on wet ground.

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.
