Heavy Disc Harrow BD-4.2M for Effective Soil Preparation and Tillage

Disc harrows of BD series with working elements of increased resource, with weight per 1 disc, not less than 115 kg, designed: for cutting clumps after ploughing, processing surfaces of compacted soils, weed killing and shredding of plant residues after harvesting thick-stemmed row crops, loosening and preparation of soils, as well as for maintenance of meadows and pastures, for basic cultivation and preparation of soils for sowing in minimum, soil-protective and energy-saving technologies. Economical use of the harrow is ensured by clad discs of increased resource, which surpass domestic analogues in terms of total resource by 2-2.5 times, inter-repair resource by 3-5 times, as well as in terms of agrotechnical and energy (traction resistance, running stability, crumbling) indicators by 11-23 %. Working time per 1 disc - not less than 30 ha; increased, in comparison with domestic analogues, harrow weight (not less than 115 kg, falling on 1 disc) allows to achieve a reduction in the number of rev... .
