The purpose of this article is to determine the degree of increase in productivity and efficiency of an excavator equipped with a bucket with a variable cutting-edge shape. The work of excavators with buckets, in which the shape of traditional and cutting blades has changed, was compared. A quantitative picture of maximizing the productivity of the excavator during the development of various soils was determined. The possibility of adapting the cutting edge itself depending on soil conditions was investigated. In addition, the influence of the adaptation of the cutting edge of the bucket on the technical characteristics and mode of operation, power, and energy parameters of the digging process was determined. The obtained results of determining the technical characteristics of the excavator with a different shape of the cutting edge and the contact component of the excavation resistance were compared with the results of buckets of the usual type. Processing of experimental data made it possible to obtain a regression model that determines the factor of dependence of response functions on transforming factors.
