The article presents the results of the theoretical determination of the main dimensions of the disk reel of the combined plug, which consists of a reel equipped with discs with a smooth working surface and smoothing-densifying working parts equipped with plates forming a fine layer.

According to the results of theoretical studies, it was determined that in order to ensure high-quality crushing of the soil at the depth where the seeds of repeated crops are thrown and compaction at the required level, the depth of immersion of the roller discs into the soil should be 3-5 cm, the diameter should be at least 40 cm, the angle of sharpening should be 60°, and the thickness should be 3 cm.
