The uniform distribution of chopped straw across the working width of the headers of 9–12 m posed a significant production challenge during grain harvesting in the conditions of the northern region of Kazakhstan. Research methods included theoretical and experimental studies. It was found that in order to increase the width and reduce the uneven spread of the chopped mass over the field, it is necessary to ensure that the initial speed of the chopped straw ejection is 63 m/s and the angle of inclination of the trajectory of the chopped mass to the horizon is about 15 degrees; and the ejection of the chopped mass should be carried out from the fourth sector of the left spreader and the third sector of the right spreader, closer to the periphery of the radius. Based on the results obtained, a low-energy straw spreader was developed and tested. It has been established that with a straw moisture content of 10–20%, the developed spreader provides a maximum spread width of 12–10 m, respectively, a distribution unevenness of 19–27%, and a chopping length of 23–25 cm.
