Abstract
The programme and the procedure of the experimental laboratory and field investigations of the shank parameters and the interaction process of a concave disk spring shank and a soil medium under ballast operating element loading, if there is a change in the travelling speed of a unit, have been developed. Estimation of the measurement results has been conducted based on the uncertainty concept. Under ballast loading (optimal reduced mass), the influence of the random components of a draft force on the process of interaction of a concave disk on a spring shank and the soil is at least one and a half times less. According to the results of the experimental studies, the dependences that show the influence of a unit speed and an operating element reduced mass on the drag force (energy indicator) and the elastic deflections of a shank (an agro-technical indicator) have been determined. Technical and economic assessment of the operating efficiency of tillage equipment according to the operating cost structure and based on practical implementation has been conducted.
