摘要

P MECHANISM FOR ADJUSTING THE WIDTH POSITION OF THE FIRST BODY OF A PLOW AND THE POSITION OF THE THEORETICAL DRIVE POINT OF THIS PLOW. /P P THE AGE OF THE PLOW IS CONNECTED TO THE PIVOT OF THE 'THREE POINT HITCH, WHICH CONSTITUTES ITS BINDING TO THE TRACTOR, BY TWO ARMS WHICH FORM A ARTICULATED QUADRILATER. ONE OF THESE ARMS TRANSMITS TRACTION, BENDING AND TORSION EFFORTS AND THE OTHER IS AN ADJUSTABLE LENGTH MEMBER. A DIAGONAL ARM IS MOUNTED BETWEEN THEM IN A WAY TO MODIFY THE VALUE OF THE ANGLES OF THIS QUADRILATER. THE ADJUSTABLE LENGTH ARM ALLOWS TO CHANGE THE WIDTH POSITION, THE DIAGONAL ARM ALLOWS TO ADJUST THE POSITION OF THE THEORETICAL DRAWING POINT. /P P APPLICATION TO WEDDING PLOWS. /P
