Abstract: A reversible plough (10) which is intended to be mounted on and towed behind a propelling vehicle, and which comprises a forward section (11) with reversible plough bodies, a rear section (13), and an intermediate wheel supported section (12, 112) which supports the rear end of the forward section and the forward end of the rear section, in which: an adjustable 3-point support linkage (28, 53, 58) is mounted on the intermediate section (12) and which supports the forward end (22) of the rear section (13), and which is adjustable to control the inclination of the plough beam (23, 123) of the rear section, and a headstock type of coupling (29, 50) which interconnects the 3-point support linkage and the forward end (22) of the rear section which permits rotary adjustment of the rear plough beam for plough body reversal, and without taking any part in this adjustment movement.

Abstract: The invention relates to an adjusting arrangement in a semi-mounted, preferentially reversible plough, comprising an elongate plough frame (4-6) carrying a plurality of plough bodies (9) and being supported on wheels (11). The elongated plough frame (4-6) comprises: an interconnected front main plough frame (4), rear main plough frame (6) as well as intermediate frame section (5). The front and rear main plough frames (4, 6) each carry plough bodies (9). The front end (at 3) of the front main plough frame (4) is laterally adjustable for adaption to one of a plurality of mutually differing ploughing widths, and each single plough body (9) is correspondingly adjustable. The technical effect sought to be achieved by the invention consists in automatically ensuring correct lateral spacing between adjacent plough bodies for all ploughing widths as soon as the spacings have been set and being equal for one adjusted ploughing width.
