The control circuit has three hydraulic jacks. The lifting jack (1) is placed between the chassis (10) of the loader and one arm (11, 12). The compensating jack (2) is also positioned between the chassis and the arm, the bucket jack is placed between the arm and the tool. The bucket jack allows the tool to pivot to empty its contents when lifted and to fill the tool when the arm is retracted. The chamber (22) of the compensating jack is joined to the chamber on the rod side (6) of the bucket jack. The bucket jack (3) has two co-axial bodies, a main section (33) and an auxiliary section (301 passing from the side opposite the rod of the jack (33).
