Supported changeable frame for soil working implements

A system for supporting, controlling and changing between multiple positions of a frame, the frame being intended for being dragged by a dragging device and for use with agricultural soil working implements connected with the frame, the soil working implements creating drag forces when used, the system comprising:

• the frame comprising a plurality pivotable connected frame sections being operable in a number of positions and changeable between these positions, and wherein the frame comprises:
• a centre frame section having a left and right side end and wherein the centre frame section is provided for being connected to the dragging device, and said frame furthermore comprising:
• one or more additional frame sections pivotable connected by one or more pivotable connections to the centre frame section in at least one of the left and right side ends of the centre frame section, said additional frames frame sections comprising:
• a first frame section having first and second opposing ends and being pivotable connected to the centre frame section on one side of the centre frame section in the first end;
• a second frame section having first and second opposing ends and being pivotable connected to the second end of the first frame section in the first end, and wherein the system furthermore comprises:
• a length adjustable connection between at least one of the additional first and second frame sections and the dragging device, wherein
• the length adjustable connection is arranged in an angle between the additional frame sections and the dragging machine and wherein,
• a length of the length adjustable connection is controlled so as to obtain drag forces from the soil working implements when being dragged by the dragging device, and wherein the length adjustable connection is so arranged that changing the length of the length adjustable connection at least partly supports and at least partly powers a change of the position of the frame, and so arranged that changing the length of the length adjustable connection at least partly supports and at least partly powers a change of position of the frame in both a first plane and a second plane, wherein the first plane is a substantially horizontal plane and wherein the second plane is a substantially vertical plane.
