Abstract: the article describes the relevance of increasing the performance of a single-bucket hydraulic excavator. The design of the proposed bucket is described. The diagram of the forces acting on the considered bucket during digging is presented. A mathematical model of the digging process with a spherical bucket is proposed, and assumptions are made to it. Dependencies for finding the parameters of the mathematical model are described. The solution of a mathematical model is presented in order to determine the dependence of the speed of the soil and bucket on the force of the hydraulic drive. An algorithm for selecting the force of the hydraulic drive when digging the soil with a bucket of the proposed design is described.
