摘要：
FIELD: agriculture.SUBSTANCE: wide-cut multi-functional tillage unit comprises a frame (1) with a trailer (2). The frame (1) rests on two air castors (3) and comprises in the rear part a medium movable spragger (4), the rotation of which is carried out by the hydraulic cylinders (5). At the ends of the medium movable spragger (4) the joints in the form of crosspieces (6) are mounted with the lateral movable spraggers (7) fastened on them, with the working transport wheels (8). On the medium movable spragger (4) and on the lateral movable spraggers (7) the sections (41) of removable tillage working bodies are mounted. The sections (41) are mounted with overlapping on the front of neighbouring sections (41) by means of pairs of parallelogram mechanisms, the pairs of longitudinal bars (25) and the pairs of coupling collars and thus the sections (41) mounted on the edges of the lateral movable spraggers (7) are mounted behind them in the course of motion and overlap the wheels (8) in front. The sections (41) are mounted at an angle between the course of motion and with the perpendiculars to their axes. The sections (41) may be made in the form of screw rollers or disc hoes, or disc shallow ploughs. The ends of the lateral movable spraggers (7) are connected to the front part of the frame (1) by the extensions (10). The extensions (10) comprise front short (11) parts and rear long parts. The rear parts are connected with one ends to the slidably mounted on the frame (1) U-shaped drive lugs (22), and the other ends - movably on the ends of the lateral movable spraggers (7). The lower pairs of the planks of the pairs of the parallelogram mechanisms are equipped at the rear part with a system of openings with pin-retainers, and in the front upper part - the restrictive slots with restriction axes, in the front lower part there are brackets with the holes with the fingers mounted in them by pins. The springs are fixed with the second ends to the adjusting screws mounted in t
