The process of harvesting potatoes with transport support is considered as the functioning of the potato-harvesting technological system consisting of the subsystems: person (P), machine (M), environment (E) and transport (T). The evaluation of the functioning of the system was carried out according to the developed methodology, based on a probabilistic-statistical approach, using the theory of Markov random processes and correlation and regression analysis. The applied method of time-keeping observations of the work of the potato harvester (tractor MTZ-80 + KPK-2-01) made it possible to carry out element-by-element analysis of the temporal characteristics of healthy and inoperable system states. According to the obtained statistics of the balance of the shift time, some regularity is established between the parameters of the system under consideration. The results of the research can be used to identify reserves for improving the functioning of potato technological systems, as well as to develop measures to reduce unproductive time spent in performing operational, technical, technological and organizational operations for harvesting potatoes.
