One of the most indicative criteria for the effectiveness of the use of agricultural units in the technological process is the turnover of material and machines. When organizing and carrying out harvesting work with packing the crop into bales or rolls (packages), various models of distribution of packages are used when forming rows through the use of a pressing unit with a trailed storage. The introduction of the proposed models of work organization into production provides technological conditions for reducing of the turnover at the stages of loading and transportation. The paper proposes a method for evaluation of the turnover of a tractor unit that compresses the harvested material into packages (rolls or bales) and has a trailed storage. The analysis of changes in the turnover of the unit, depending on the length of the rut and the capacity of the trailer drive, was carried out. Recommendations are given for choosing a rational capacity of the trailer storage, depending on the conditions in which the packages are formed. It has been established that the use of a trailed accumulator to the pressing unit makes it possible to implement an ordered collection method with the formation of rows. The desire to reduce the number of rows on the field by changing the storage capacity does not always require a positive result. When the ratio of the run distance during the formation of the package to the length of the rut is from 1 to 4, an increase in the capacity of the trailer drive to 2 or more packages does not lead to a decrease in the number of rows obtained. With a ratio equal to 5, the rational capacity of the trailer storage is 2 packages; with a ratio equal to 6, the minimum number of rows is 3, regardless of the capacity of the trailer storage. An analysis of the results of the study showed that an increase in the capacity of trailer accumulation for the resulting packages leads to an increase in the total turnover of the unit from 6.3 to 28.9 %.
