 Disc harrows BND-1.6, BND-1.8, BND-2.8, BPTD-3-01, BPTD-7.

 

Designed for soil loosening, soil segregation by layers after plowing, for seedbed preparation without preliminary plowing, for soil treatment after harvesting tilled crops and cutting plant residues, for grassland farming.

Harrows may be used in different agro-climatic zones, on all types of soils, including those subject to wind and water erosion, as well as on the soils contaminated with stones with sizes not more than 10 cm and wood waste with thickness up to 2 cm. It is allowed to use harrows on the relief (slope, degree) up to 10 degrees, also the operation is possible on soils with rolling and smooth relief, soil moisture in the layer from 0 to 16 cm – up to 35% and soil hardness in the layer from 0-16 cm – up to 3.5 MPa. It is possible to operate harrows also in wet weather.

The battery is the main operative part of the harrow. The battery includes concave discs. Discs are set on the axis which is mounted in two bearing assemblies and separated with swifts.

The operative parts of harrows BND-1.6, BND-1.8, BPTD-3-01, BPTD-7 are equipped with cutout concave discs of “daisywheel” type with the diameter of 650 mm, thickness 6 mm. Due to a special high-technology method of manufacture and processing of discs, as well as to the material from which they are made, the life time of operative parts of the harrow significantly increases in comparison with similar machines – depending on operating conditions the wear of discs is 10 mm per 2,500 ha.

The bearing assembly consists of the ball bearing pressed in the cup. To protect the bearing against contamination cuffs are installed into covers. This results in a significant increase of lifetime and gives a malfunction warranty for the operating time of the equipment up to 10 thous.ha.

 

The Disc harrows  BND-2.8

 

The harrow is designed according to the asymmetrical double-gang scheme.

For its operation the harrow uses driving force of the tractor. During the forward movement of the unit the harrow mounted in working position is put deeper in the soil with its discs.

In the front row of batteries discs are installed with the convex inward, and in the back row – with the convex outward. With the sharp cutting edge the disc cuts the layer strip which is shifted to the side, lifted to the disc and falls on the field surface from some height. The soil layer thereat moves and crumbles without rotation. One section of discs throws the soil off to the right, and the other – to the left, there for leveling the field surface discs are in installed in two rows asymmetrically. During the operation the rear batteries throw the soil off in the opposite direction compared to the front ones.

The asymmetric arrangement of batteries allows to perform soil treatment not forming back furrows and back ridges, gives possibility to shift the draft line of the harrow to the side and remove the tractor from the trees at the required distance in such a manner.

 

Heavy mounted disck harrow BPTD-3-01

 

        The disc harrow БПТД-3-01 is designed according to the asymmetrical double-gang scheme. As distinguished from two-gang X-shaped field harrows the harrow performs soil treatment not forming back furrows and back ridges which allows to use the harrow directly before sowing without additional treatment. Moreover, the asymmetry of the batteries gives possibility to shift the draft line of the harrow to the side and remove the tractor from the trees at the required distance in such a manner which allows to treat inter-row spacing in gardens.

 It can be completed with the mulch roller.

 

Heavy mounted disck harrow BPTD-7

 

 

     The specific feature of the harrow БПТД-7 is that she has a main frame and additional wings connected with the main frame through the system of hydraulic cylinders. This provides independent movement of wings relative to each other with the irregularities of the treated surface which helps to maintain the tillage depth of the soil.

   The tillage depth during the treatment with this machine can reach up to 20 cm. The tillage depth is adjusted by changing the approach angle within 12º,15º,18º. The uniformity of penetration of front and rear batteries is adjusted by changing the height of the sighting unit above the soil surface.
