The invention concerns an apparatus comprising an arm (4) which, mounted on a support at one of its ends, comprises several elements (5, 6, 7) articulated on one another about horizontal pins (8, 9) and equipped, at its other end, with a tool-holder (15). At its free end, the arm is equipped with a rotary actuator (12) with rotation pin (12) transverse to the hinge pins (8, 9) of the elements (5, 6, 7) of the arm, and on the lower part of which is fixed a housing (15) containing a motor (16) designed to drive an output shaft (23) transverse to the rotary actuator axis and at the tip of which is mounted cantilevered a tool (33, 34). The invention is applicable to tillage on steep grounds or with marked irregular features, such as trenches.
