Abstract
The present study focuses on the improvement of plough design to ensure smooth ploughing with minimum energy consumption. Mathematical energy consumption models are obtained through mechanical methods regarding the reservoir turnover process by various dump surfaces. The results indicate that the work per revolution of a diamond-shaped configuration is smaller than that of the rectangular one. This is attributed to the absence of an additional impact of the blade wing on the diamond-shaped formation. Furthermore, the theoretical conditions were verified through a series of experiments that revealed a 10% decrease in the traction resistance of the diamond-shaped plough in comparison to the serial plough and increased productivity by 5.4%, allowing the creation of a symmetrical diamond-shaped shortened blade of a rotary plough with two-mode operation. Different angles of the working surface of the chest and blade wing to the furrow wall are examined.
