FIELD: forestry.SUBSTANCE: invention relates to forestry, particularly to designs of tillers for main belt soil preparation, and can be used for cutting landing furrows and creation of fire strips. Plough comprises hitch device, main transverse frame, two lengthwise beams with plough bodies and two safety mechanisms to deflect beams upwards due to rotation. Plough bodies are equipped with hanging cutters. Main frame has two crosswise guides for free movement along them beams plough bodies by means of screw adjustment mechanisms with carriages. Plough bodies are left-turning and right-turning and have possibility of changing their positions. Hanging cutters have one-side sharpening. Beam, safety mechanism and carriage are combined into a single unit, ensuring possibility of changing distance between bodies and possibility of tight closure of hanging cutters to form a single blade with double-sided sharpening.EFFECT: such design broadens functional capabilities of plough when operating in conditions of non-uprooted clearings.2 cl, 5 dwg |
