The article describes an optimization model for determining the number of combine harvesters and vehicles in the link. Dependences of the number of combines on the width of the harvesting unit's harvesting capacity, the crop yield, the long haulage of the crop and the load capacity of the vehicle were determined. The optimization model used is based on queuing. The calculations showed that with increasing the yield from 30 to 50 c / ha, the number of units in the link is halved, and when the harvesting width is doubled, the optimum number of combines falls from 5 to 2. In turn, reducing the capacity of the combine harvester and increasing the harvesting capacity grain transportation leads to a decrease in the number of combine harvesters in the link. With the decrease in yield by 10 c / ha, the number of harvesting units in the link increases by an average of one unit.
