Four-row disc harrows DANA

Purpose

DANA disc harrows are designed for resource-saving preplanting cultivation and main tillage to a depth of 8 to 15 cm for cereals, industrial and forage crops, weeding, shredding crop residues, rejuvenating meadows and pastures. DANA disc harrows are most effective in tilling soils free of stones, flagstone and other obstacles.

Today, RZZ CJSC produces 3 models of four-row disc harrows DANA: DANA BDP 3×4, DANA BDP 4×4, DANA BDP 6×4 as well as folded harrows: DANA BDP 6×4-MTM и DANA BDP 8×4 MTM.

Harrow models differ in cut width. In the designations of the harrows, variables "3","4", "6" denote the cut width of the cut, and the constant number "4" denotes the number of harrow rows.

Advantages

DANA disc harrows allow to:

  • prevent soil drying;
  • destroy weeds;
  • increase the microbiological activity of the soil;
  • perform nonmoldboard cultivation at a depth shorter than plows;
  • reduce the number of tillage activities, save time and money, in contrast to the traditional technology;
  • perform tillage at high humidity.

Description:

Cut-out discs in the form of concave plates with diameter of 570 mm are the primary tools of the DANA disc harrows. They are attached to the frame at an angle to the direction of the unit movement. The discs turn during the operation and cut the layers of the soil, loosen and mix the soil. The tilth changes with the change of approach angle of the discs with respect to the direction of the harrow movement. The larger the approach angle, the deeper the tilth.

The compactor roller is designed for additional crumbling, leveling and securing the loosened soil. The tilth is controlled by screeds.

Warranty

The warranty for DANA disc harrows produced from January 01, 2018, is 2 years from the date of commissioning.
