Аннотация
A new design of a disc harrow is proposed. The mathematical dependences of quality indicators of soil preseeding processing on the design and technological parameters of the harrow are obtained. The optimal values of the disk radius (r = 0.25 m), the distance between the discs (d = 0.165 m), the angle between the discs (γ = 10.8°C), the deviation angle of the axis bending (φ = 53°C), and the motion speed of the unit (Ve = 3.25 m/s) were determined. The soil crumbling under these parameters occurs within the range from 87.5 to 93.1%, soil ridgeness is provided from 30.8 to 36.3 mm, and drought resistance is from 4.96 to 8.19 kN.
