The headers of modern combine harvesters are mainly equipped with passive side dividers. When harvesting lodged and tangled crops (for example, peas), plant mass accumulates on passive side dividers, the harvested strip is poorly separated from the rest of the field, which leads to a decrease in combine productivity and an increase in losses of the grown crop. To eliminate these shortcomings, the design of an active field divider is proposed, the main working body of which is a disk cutter. The article describes the design of the active side divider, provides a laboratory setup and describes the methodology for laboratory research to justify the optimal design and operating parameters of the proposed divider. The studies were carried out using the theory of multifactorial experiment. The optimization criteria are the completeness of separation of tangled stems and the amount of losses of the grown crop. The completeness of the separation of tangled stems is determined visually and by photographing, and the losses are determined by the method of collecting and weighing crumbled grains. As the results of laboratory studies show, the smallest losses are provided with the number of teeth of the disk cutter z=8 pieces, the frequency of rotation of the disk cutter n=125 min-1 and the operating speed of the feed conveyor vр=2.0 m/s. At the same time, the active side divider works stably, the completeness of separation of tangled stems is 100%. the smallest losses are provided with the number of teeth of the disk cutter z=8 pieces, the frequency of rotation of the disk cutter n=125 min-1 and the operating speed of the feed conveyor vр=2.0 m/s. At the same time, the active side divider works stably, the completeness of separation of tangled stems is 100%. the smallest losses are provided with the number of teeth of the disk cutter z=8 pieces, the frequency of rotation of the disk cutter n=125 min-1 and the operating speed of the feed conveyor vр=2.0 m/s.
