Adjusting devices for a semi-mounted plough

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. According to the invention, this is realized in that the intermediate frame section (5) constitutes a parallelogram (12-19), adjustable to and lockable in different angular positions in relation to the mutually parallel longitudinal axes of the front and rear main plough frames (4, 6).
