It is understood that the ridge construction of paddy fields in my country is completed by manpower. Even if some special tools are used, the labor intensity is still high, the work efficiency is low, and the uniformity and consistency of the ridges are poor. Through investigation and research, we learned that there is some research on ridge-building machines in our country, but the general ridge-building machines only have the function of building ridges without the function of rotary tillage, and the operation function is relatively simple. There are many operations on cooked land with clayey soil and short transport distance, and the operation efficiency is low, but there is no large-scale land preparation and ridge building combined operation machine for large-scale plains.
