Abstract
Introduction. At present, there is widely used smooth plowing, which is moldboard plowing without back ridges and deep furrows.
Aim of the Article. The article deals with developing a new design of working tools for smooth soil plowing that ensure the fulfillment of the required quality of soil cultivation.
Materials and Methods. Based on the analysis of existing designs, the authors developed a harrow with a turning disc section, which is characterized by increased operational reliability by reducing energy costs for its adjustment. The range of change in the approach angle of the disk working bodies is 5–45°.
Results. It was found that the speed of movement and the inclination angle disks have the greatest influence on the tillage quality. To optimize the motion parameters with a turning disk section for the best smooth plowing quality, a two-factor experiment was carried out.
Discussion and Conclusion. As a result, it was found that at a speed of 9.113 km/h and approach angle of working disks of 32°, the quality of tillage is maximum and amounts to 86.1%.
