Multiple section reversible plough

A reversible plough which is intended to be mounted on and towed behind a propelling vehicle, and which comprises;

• a forward section having a forward end and a rear end, said forward section comprising a plough beam having a number of pairs of reversible plough bodies arranged along its length, and said plough beam being adjustably mounted at its forward end in order to move an upper inoperative plough body of each pair to a lower ploughing position in order to reverse the plough bodies;
• an intermediate wheel-supported section arranged to support the rear end of said forward section;
• and,
• a rear section having a forward end and a rear end, said forward end being supported by said intermediate section, and said rear section comprising a respective plough beam having a number of pairs of reversible plough bodies arranged along its length, and being adjustably mounted at its forward end to move an upper inoperative plough body of each pair to a lower ploughing position in order to reverse the plough bodies;
• characterized by:
• 1) an adjustable 3-point support linkage which is mounted on said intermediate section and which is coupled with the forward end of said rear section, said linkage serving to control the inclination of the ploughbeam of the rear section relative to the intermediate section whereby:
• a) the rear section can be lifted by the linkage during plough body reversal;
• and b) the rear section can be adjusted to any desired inclination for ploughing;
• and
• 2) a coupling between the linkage and the forward end of the rear section which permits rotary adjustment of the plough beam for plough body reversal and without taking part in this adjustment movement.
