TOWED REVERSIBLE PLOUGH WITH VARIABLE WORKING WIDTH HAVING A DEVICE FOR RECENTERING THE FRAME TO THE RETURN AXIS

摘要

The claimed plough comprises a balance parallelogram (ABTE), a jack allowing the recentering of the frame with respect to the return axis without modifying the adjustment of the variable working width and of the balance. Said jack defines one side of the balance parallelogram. According to one embodiment, it is positioned between the transverse beam (3) and the axis (F) located in the middle of the side (AE) of the balance parallelogram. The balance jack (21) is positioned between the intermediate transverse bar (19) which divides the balance parallelogram, and a shoe (22) of the undercarriage (4), in order to provide for an automatic correction of the balance of the first body with respect to the tractor, up to the adjustment of the working width.
