<p>The plough comprises a supporting head (1) equipped with a pivot (5) and with an axle (12) respectively carrying the frame (3) and a supporting arm (10), the other end of which is fixed to said frame (3). The front end (9) of the frame (3) comprises a system for guidance by means of a slot (6) in the form of an arc of a circle, the imaginary centre (14) of which corresponds to one of the angles of a parallelogram, the other angles of which are formed by the axes (5, 12 and 13). The offsetting of the frame (3) by means of the jack (15) interposed between the latter and the arm (10) causes a displacement of said frame (3) parallel to itself. A device for adjusting the axle (13) in relation to the frame (3) by means of a screw-type or hydraulic jack (15) makes it possible to carry out either a correction of camber or a variation in the working width of the bodies (4) or else a recentring of the frame (3) for overturning. <IMAGE></p> |
