ABSTRACT:
The invention relates to an implement for treating soil and, in particular, to an implement used to improve the hygroscopic properties of the soil by making holes in it using one or more tools mounted on an irregular, variable, quadrilateral jointed structure pivoted to a frame and actuated by a linkage system which can modify its configuration in such a way as to drive the tool into the soil and then angle it gradually so as to widen the bottom of the hole.
