Abstract
The paper presents a general view of the new working surface of the harrow with helical working tools. With the help of SOLID WORKS software package, a computer model of this soil tillage tool with helical working tools for surface tillage has been created. The obtained new analytical dependence made it possible to determine the traction resistance of the harrow, equipped with a spiral working element which, in turn, served as the basis for constructing graphs, showing a change in the traction resistance depending on various values angle of attack of the harrow and the soil resistance.On the basis of a computer model of a helical tillage tool created in the SOLID WORKS program, it was found that when the angle of attack of the tool increases, the drag resistance P increases, as well, and its greatest increase is observed for the maximum diameter of the tool D. It was found that the thickness of the helix λ has a much smaller effect on the traction resistance compared to the parameter D.
