OLT Sava disc harrows (20, 24 and 28 discs) are classic disc harrows used for soil preparation after plowing and before sowing. The difference between the models is in the width of the grip: 20 discs are about 1.8 m, 24 discs are about 2.1 m, and 28 discs are about 2.4 m. The discs are usually about 460 mm in diameter and work a depth of about 8–12 cm.
