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.

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.

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 rotary tiller uses the power output from the tractor to drive the rotary blades to cut and turn the soil. These blades shred the soil and throw it backwards, further breaking it after colliding with the mudguard. Finally, the surface is scraped and leveled by a flat soil pallet, completing the plowing and raking operations in one go. 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.
