Disc harrow BPTD-3-01

Disc harrow BPTD-3-01 is 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 disc harrow BPTD-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.
