Best-quality seeds of high-yielding commercial cultivars are the foundation of the future harvest in all crops. Significant seed damage arises from seed injury during harvesting and tillage. With the use of machinery in all harvesting and processing stages, the issue of seed injury has become severe. Therefore, the presented research sought to determine commercial soybean seeds’ properties and seeding qualities, depending on the cultivar properties and the influence of machinery used in harvesting. The identified degree of soybean seed injury of commercial soybean cultivars depends on the growing strength after harvesting with drum threshing combined with the harvesting equipment’s influence. Based on biological characteristics, the soybean cultivars differed significantly in the number of damaged seeds during harvest using the drum thresher type ‘Sampo SR 2035’. However, the soybean cultivar Birlik KV showed the minimum seed damage (49.5%), whereas the cultivar Zhansaya had the most seed injuries (83.0%). According to laboratory tests, high intensity of initial growth resulted in seeds of soybean cultivars Birlik KV (86.0%), followed by Perizat (82.0%), and Lastochka (78.0%). Seeds of the soybean cultivars Ivushka and Zhansaya had the lowest growth strength (52.0%–60.0%). The most injury-prone soybean cultivar Zhansaya exhibited 21.3% crushed and inured seeds when their threshing used a drum thresher, but when threshed with a rotary thresher, the number of damaged seeds decreased to 2.9%. For injury-resistant soybean cultivar Lastochka, the harvester Sampo SR 2035 produced 12.4% injured seeds, and the harvester ’John Deere’ generated 2.2% crushed seeds.
