The motivation of the research and further development of the new type combined knife system on the non-return bulldozer blade and the results of the first series of laboratory studies of the process of the soil digging with the non-return blade of the bulldozer with the first set of its physical models, which indicate the feasibility of continuing research in this direction is given. The proposed combined knife system makes it possible to realize oblique digging of the soil on the non-return blade of the bulldozer and maximally complete its orientation in the prism of the soil before the blade in order to increase the productivity of the bulldozer with non-return blade by decreasing soil losses in the side rollers, decreasing the time of filling and digging the soil by decreasing the coefficient of specific soil resistance to digging. The paper substantiates the technology of more efficient use of bulldozers with non-return blade compared to their traditional counterparts, which is possible due to the use of the new combined knife system, and argues in favor of expanding the technological capabilities of the bulldozer with non-return blade, equipped with the proposed engineering solutions of the new type knife system with different digging angles and spatial inclination of cutting edges.
