The study of the resistance of the bulldozer blade burial at a stationary machine is aimed at studying the force factors acting on the working tool during its penetration into the ground. When the machine is not moving, the blade deepening causes an increase in passive resistance from the ground, which acts on the front and rear edges of the blade. This resistance increases with the depth of burial, which requires an increase in force for further advancement of the working body into the ground. An important feature is that in the initial stages of blade insertion, the resistance at the front face increases significantly, increasing the forces. At the rear edge, the re-sistance also increases as the blade deepens. Cutting angles have a significant effect on resistance changes: at higher cutting angles, the resistance decreases, reducing the load on the working mechanisms. The results of the study emphasize that for efficient knife deepening with the machine stationary, higher cutting angles should be used, which reduces passive resistance, improving productivity and reducing energy costs.
