Soybean is one of the most important crops. The density of the seedlings should be 200-300 thousand per hectare, 300-400 thousand seeds, and 400-500 thousand early varieties. In this article results of research in the field and laboratory are shown for sowing soybean seeds using SCHX-4 sowing machine and its mechanical sowing apparatus. In the experiments, the number of measurements at the sowing depth was 100 and the number of lines was 10. The sowing capacity was 35-40 kg, the sowing depth was 4 cm and the width of the line was 90 cm. During the experiment, the difference in sowing measure between real sowing and SCHX-4 which has a mechanical apparatus was 6.75% and the average sowing depth and its standard deviation were 3.8 and 0.31 cm respectively. The width between the main and side rows was 89.5 and 92.5 cm respectively, and the damage level of seed caused by seeder SCHX-4 was 5.2 %. This apparatus did not reach agro-technical requirements. Thus a restrictor was installed was made from rubber and formed a semi molded formation on the hole where the seed enters the sowing apparatus which decreased the seed damage to 0.8 %.
