Trailed disk harrow with 2 x in-line arrangement of the working bodies (disks). 2 BDM,4х2П (hereinafter - harrow) is designed for loosening and preparing the soil for sowing; weed destruction and chopping stubble residue; for seedbed preparation without prior plowing and tillage after harvest tolstosheina (in two passes) of row crops. Independent row control angles of attack of the discs improve agronomic performance of tillage, as well as reducing the required tractive effort of the tractor. The absence of a single axis for multiple disks eliminates the winding of plant residues and eliminates the necessity of application in the design of the scraper. The harrow is designed to work on all soils with soil moisture not more than 28%, the slope of the surface field of not more than 10°, the hardness of the soil in the treated layer is not more than 3.5 MPa. Not allowed the contamination of soil heavy accumulation of straw and crop residues, as well as stones and tree roots. Name of indicator Unit of measure index Value Type of harrow trailed Productivity per hour of basic time, not less than 2,4 hectares Operating speed , no more than km/h 10...16 Transport speed , no more km/h to 20 Working width at an angle of attack of the discs 20° m 2.4 The depth of the soil ,not more than 16 cm Weight with equalizer soil kg 1200±20 Attack angle (cutting or nodes) degrees. 0...30 The number of working bodies (disks): in one series of 8 PCs. - total 16 PCs.
