摘要：
The solution relates to agricultural machinery, in particular to implements for tilling the soil surface treatment, which can be used for the treatment of cultural, and schebenchatyh rocky soils, as well irrigated and non-irrigated soil.Harrow, comprising a frame with welded uprights bearing assembly to the front of the frame board, and moving the rear strut with bearing assemblies located on the cantilever beam of the frame. Between the front bearing assembly and the corresponding rear bearing unit tensioned chain with fixed teeth, the chain arranged on the rigid frame from the left motion vector stroke angle of 45 degrees in an amount of 3-4 pieces in parallel and symmetrically to the right. Chain tension is performed with emphasis threaded lock nut located below the cantilever beam, abutting against the rear rack of the bearing assembly via a thrust bearing, and the burial harrows adjustment is effected by changing the height of the wheel struts disposed on the harrow frame in an amount of 4 pieces. The transformation of the side sections harrow in transport position and carried back cylinder on the rear frame beam by means of the series-arm supports and the rods. Racks wheels may be disposed on the harrow frame in an amount of 3 pieces. The teeth of the chain elements at the ends are cut at right angles. The teeth of the chain elements have pointed cone at the ends of the teeth.The technical result - decrease of metal harrow without loss of efficiency and performance.1. Борона, содержащая раму с приваренными стойками подшипникового узла к переднему брусу рамы, и подвижные задние стойки с подшипниковыми узлами, находящиеся на консольных балках рамы, отличающаяся тем, что между передним подшипниковым узлом и соответствующим задним подшипниковым узлом натягиваются цепи с жестко закрепленными зубьями, причем цепи расположены на жесткой раме слева от вектора хода движения под углом 45° числом 3-4 штуки параллельно, а справа симметрично натяжение цепи осуществляется р
