The harrow contains two rows of disks, each of which is located on an individual rack, which is attached to the bar with two L-shaped brackets (diameter 20 mm). This design excludes clogging of the interdisk space. The harrow can be used in all soil and climatic zones where the soil moisture does not exceed 27 percent and the soil hardness does not exceed 3.5 MPa, and it is also not recommended to use this harrow in areas with significant stony inclusions. Due to the use of individual racks in the design, the front harrow can be used at high working speeds - up to 14 km/h.(//tractor-service.com)

Disk working body, which is a cut-out spherical disk (chamois) installed on the hub, with a diameter of 650 mm. and 6 mm thick, with internal sharpening along the entire contour. Thanks to the special geometry of the trunnion rack, it is installed at an optimal angle of attack to the line of traction and an angle to the vertical, which ensures high-quality crushing, crushing and turnover of the cut layer.

Unlike similar harrows of other manufacturers, the design of this harrow uses camomile disks (cut-out spherical) with a diameter of 650 mm and a thickness of 6 mm, made of 65G steel. During manufacturing, the discs are thermally treated, which ensures a hardness of 36-42 HRC.

Disks are installed on hubs that rotate around an axis on roller bearings (Podshipnyk 127509 - UAZ hub) nodes at an angle of attack and a vertical inclination of 21 degrees.

The metal anther, which is installed on the axis during assembly, covers the hub, forming a protective structure, which is supplemented by a sleeve with an oil seal inside and an anther outside. The unit is very well sealed from the outside environment due to this design.

The fixing and adjusting nut of the hub bearing is closed by a flange with a cap, which performs two functions:

hub sealing
fastening of the working body (BDF disc) to the hub.
The scraper is attached with two bolts with square headrests to a bracket with two grooves, which, in turn, is welded to the rack and when the harrow is working, it cleans the working organ (disc BDF camomile) from sticking to the soil, winding up plants, clogging the harvest residues, and also directs the flow of soil in the direction of the harrow and turns it.

The rear rollers of the harrow provide two functions:

crushed soil
compacts and aligns the surface
In addition to the above-mentioned functions, with the help of a roller for hinged harrows, the depth of soil cultivation is set, which varies, as indicated above, from 8 to 18 cm.

The necessary depth of loosening and the stable movement of the harrow-tractor unit are provided by the lanyard (screw mechanism with right and left thread), which ensures the adjustment of the vertical position of the roller.

The harrow is aggregated with tractors equipped with a hydraulic system with a capacity of from 80 (for the BDFP-2.4 trailed harrow) to 200 (for the BDFP-4.2 trailed harrow) horse power, depending on the tool's grip width.

With the help of lanyards, the stroke height (processing depth) of a plate roller with a diameter of 400 mm is adjusted.

The construction of the rink attachment allows you to shift (move) the rink to the left or right (if necessary).
