Disc harrows BDM-P “BARS" on a spring rack, Ufa

• Four-row harrows have a fairly large distance between the discs in a row. The distance between the discs in a row is 460mm, the distance between the rows is 675 or 900mm. Therefore, the earth thrown by a row of disks easily passes between the disks of the next row. Thus, the four-row harrow is capable of working in fields with high contamination and at great depth.
