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.

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.

In order to fully utilize the efficiency of rotary tillers and ensure their safe and efficient operation, users need to master the correct usage methods. Firstly, before use, check whether all components are intact, especially whether the rotary tiller is installed backwards, and whether the fixing bolts and universal joint locking pins are secure. Secondly, before starting the tractor, the clutch handle of the rotary tiller should be set to the disengaged position, and the power should be engaged in the raised state. After the rotary tiller reaches the predetermined speed, slowly lower it to let the rotary tiller blade enter the soil. During the operation, it is strictly prohibited to start, reverse, or turn the rotary tiller directly when it is in the soil, in order to prevent damage to the equipment.

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.

The vertical rotary tiller is mainly suitable for stubble cutting operations, and its working components are rotary tillers equipped with 2-3 spiral cutters. During operation, the rotary tiller rotates around the vertical shaft, and the cutters chop the soil into small pieces. This type of machine has strong soil crushing and pulping properties, but its coverage performance is poor. The inclined rotary tiller is a new type of tillage equipment that combines the characteristics of plowing and rotary tillage, with low power consumption and good tillage quality. It releases soil constraints, reduces power consumption, and tillage resistance by tilting the blade axis.
