A small tiller uses its power unit (such as a gasoline engine, diesel engine, or electric motor) to drive rotary blades or other tillage components to rotate, cutting, turning, and crushing soil. The rotary tillage blade shreds the soil during rotation and throws it backwards, further shattering it after colliding with components such as the mudguard. Finally, the surface is scraped and leveled by a leveling device. During this process, the soil is finely divided, the soil and fertilizer are evenly mixed, and the surface becomes flat, providing good conditions for subsequent sowing or transplanting.

Small tillage machines, as an important component of modern agricultural machinery, play an important role in farmland cultivation due to their lightweight, flexible, and efficient characteristics.

As a powerful assistant in modern agriculture, rotary tillers play an important role in agricultural production. Through proper use and continuous improvement, rotary tillers will better serve agricultural production and contribute to the development of modern agriculture.

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.
