The article is devoted to the interaction of the cutting face of a scraper with a destructible medium during the development of a trench. Reducing the arising forces in the process of soil destruction can be achieved by various technical solutions. The simplest and least costly method is the method of the cutting elements design improving. The forces arising during the contact of the cutting element with the ground are considered. The interaction of the cutting element and the ground process is considered taking into account the stressed soil state before the cutting edge and the cutting angle digging and the cutting edge shape resistance effect. The calculated dependencies determining the scraper middle part width rational values and the scraper middle part boom rational parameters are obtained.
