This is a study that aims to conduct a set of simulation experiments on varying the loading parameters of the machine and tractor fleet of an agricultural enterprise. The following objectives are set: to substantiate the features of constructed simulation model of loading machine and tractor fleet; to vary the units using the example of implementing various technologies for cultivation and harvesting of wheat after fallow; to evaluate the technical and economic indicators of various technologies for cultivation and harvesting of wheat after fallow. The simulation model is based on end-to-end viewing method of annual work package options. During the experiments, the parameters of the field ripening coefficient, crop yield, set of units and average technical reliability coefficient are varied for different types of technologies and natural areas. As an example, estimates based on technological maps of steam cultivation and harvesting of wheat for the forest-steppe zone of the Novosibirsk region are given. The completed volumes of work, equipment loading, duration of operations, fuel consumption, fuel and lubricants costs are calculated. An assessment of the economic indicators of technologies has shown that intensive is the most expensive, but more effective, although there are small differences in indicators on the example of one crop production. When considering the entire crop production of an agricultural enterprise, costs and profits increase significantly, and intensive technology remains the most effective.
