Abstract: Deep tillage is capable of penetrating the tough subsoil layers, while vertical rotary tillage improves soil aggregate structure and moisture retention. In this study, an innovative deep vertical rotary tiller was engineered. Utilizing ANSYS Workbench, stress simulation on the blade was conducted. The EDEM software was employed to explore how the machine's forward speed and the blade's rotational speed impact operational quality. Field trials of the developed prototype revealed that the tillage depth, tillage depth stability coefficient, and soil fragmentation rate all complied with the national standard GB/T 5668-2017 for rotary tiller testing. Comparative analysis with the current vertical rotary tiller confirmed that the tiller developed in this study exhibited superior performance, thereby facilitating the adoption and technological evolution of vertical rotary tillers.
