The results of research on the effect of the nominal tractive force (class) of tractors, the level of their reliability, the price and applied technology of tillage on labor productivity and cash expenditure are presented in this study. It is established that the application of zero tillage technology has the greatest impact on increasing labor productivity (2.5, …, 3 times) compared to soil protection technology. Increasing the nominal tractive force of tractors from 40-50 to 60-80 kN and applying the minimum tillage technology provides an increase in labor productivity for 1.9, …, 2 times and decrease in aggregate costs compared to soil protective technology.
