The article deals with an economic-mathematical model of optimal distribution of the amount of work among the tractor aggregates considering the fixed agrotechnical terms for the execution of production processes in the field crop cultivation. A method of linear programming is applied to solve this task. A theoretical relationship is presented between the rated costs per hectare and the performance characteristics of the tractor aggregate. This is shown by an example of a calculation of the optimal distribution of the amount of work among four tractor aggregates performed in ploughing and sowing. The developed model provides an opportunity to make a motivated conclusion how to perform the work with optimal variable expenses reducing the losses of crops after harvest owing to fixed agrotechnical terms as well as to justify the structure of the technical provisions of the production processes.
