In the context of the country’s growing self-sufficiency in foodstuffs, including potatoes, commodity producers need to purchase potato harvesters and devices. The choice of potato harvesting equipment should meet the needs of agricultural producers (potatoes) while contributing to the improvement of agricultural performance. In this situation, enterprises are faced with the problem of choosing potato-harvesting equipment: cheap but low in productivity, or expensive but high-tech. To substantiate the choice of using machines for harvesting potatoes, it is possible to use the method of expert assessment, which allows choosing among a variety of alternatives, based on the preferences and justifications of experts. The use of the mathematical apparatus makes it possible to compare various physical characteristics by reducing them to a dimensionless scale. As a result of studying the most common trailed potato harvesters, the KKP-2M trailed harvester possesses the optimal ratios of the cost of the machine, productivity and quality of the resulting product. Trailed potato harvesters at a lower price have technical parameters that are not much inferior to self-propelled machines. This conclusion is confirmed by such methods as “Score table” and “Polygon for alternatives”. The first method provides a mathematical justification and the second one allows visualizing the resulting solution.
