摘要：As compared to the cultivators, the disc harrows facilitate the performance of shallower stubble cultivation and mix better the stubble with the soil [1] and, thanks to cutting the harvest residues, they are less exposed to clogging. The classic disc harrows with the sections set askew to the work direction are superseded with compact disc harrows where the discs are secured individually and are set in two parallel rows. Use of the harrow after sowing enables covering the cultured seeds with a thin layer of soil [2]. An example of a disc harrow is shown in Fig. 1 [3].
