FIELD: agriculture. ^ SUBSTANCE: tool comprises a stand with a block with an attachable chisel welded in the bottom part. Along the stand there are holes drilled, through which movable mouldboard and a pair of cutting wings may be fixed with a pair of bolts. The tool has an eccentric bushing, which is inserted into holes of the stand and is rigidly connected to a fastening bolt. The hole in cutting wings is made in the form of a vertical slot, providing for rotation of eccentric for the required angle. ^ EFFECT: design version will make it possible to optimise the required quality indices for specific soil and climate conditions at lowest operation-process and power inputs. ^ 3 cl, 3 dwg |
