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 plough beam provided with a number of pairs of reversible first plough bodies spaced apart along the forward plough beam, said forward plough beam having a forward end which is adjustably mounted in order to reverse the first plough bodies;
• a rear section having a rear plough beam provided with a number of pairs of reversible second plough bodies arranged along the rear plough beam, said rear plough beam having a forward end which is adjustably mounted in order to reverse the second plough bodies;
• a connecting frame portion which interconnects said forward section and said rear section, the connecting frame including a pair of separated support beams;
• a wheelset mounted to the connecting frame, the wheelset being arranged to support a rear end of the forward section and the forward end of the rear section;
• a headstock mounted to the separated support beams via respective securing brackets, the headstock mounting the forward end of the rear plough beam to the connecting frame so as to permit rotation of the rear plough beam through an angle of approximately 180.degree. in order to reverse the second plough bodies, the headstock also being adjustable in order to vary the inclination of the rear plough beam to adjust the rear section between a ploughing position and an inoperative transport position;
• a mounting bracket connected to said forward plough beam of the forward section, said bracket being rotatably mounted on said connecting frame portion to allow said forward plough beam to be rotated through approximately 180.degree. in order to reverse the first plough bodies;
• and
• means for rotatably mounting said bracket on said connecting frame portion and also providing a drive coupling to the forward end of said rear plough beam, whereby joint adjustment rotation of said forward plough beam and said rear plough beam can take place in order to reverse the plough bodies of the forward and rear sections simultaneously.
