Economic and technological parameters for optimal use of tractors

Abstract

The application of modern agricultural machines and tools in plant production involves the use of all parameters that are necessary for optimal exploitation of tractors as well as economic scientific research aimed at application of scientific knowledge in practice. This paper presents the results of an analysis of optimum operating parameters of tractors in order to achieve maximum effect, which will result in economic justification. It was found that the maximum effect coincides with the maximum coefficient of tractor efficiency; that the increase in engine power led to proportional increase in the efficiency; that technological power consumption was in function of the tillage depth and soil specific resistance. In addition, potential energy consumption of tractors per hectare depends on the structure of energy during exploitation.
