A conditioning system for conditioning a ground surface having a base layer and a cushion layer. The conditioning system includes at least one conditioning element adapted for conditioning the ground surface, a floating frame adapted for supporting the at least one conditioning system to maintain desired contact with the ground surface, and a levelling system for defining a desired spacing between a base layer of the ground surface and the at least one conditioning element to define a cushion layer. In one embodiment a first conditioning element and a second conditioning element are provided where the first conditioning element is disposed at a first angle relative to a directional axis and the second conditioning element is disposed at a second angle relative to the directional axis and wherein the first conditioning element is offset from the second conditioning element relative to the directional axis.

Described is a structural element for agricultural equipment comprising at least one pair of transverse beams associated with at least one pair of support bars of a set of agricultural discs, where the longitudinal distance between the beams of the pair of transverse beams is smaller than the longitudinal distance between the bars of the pair of support bars. This construction allows a greater free space for the flow of material cut by the discs (soil and plant residues) and a decrease in the occurrence of stops to clear the obstruction or even the formation of heaps on the ground, while still promoting an adequate arrangement for the absorption and dissipation of efforts that act on the structural element.

A hoeing device includes: a frame intended to be coupled to a vehicle for towing the hoeing device; and a deformable parallelogram having comprising an upper beam and a lower beam carrying at least one hoeing tool as well as an element for running on the ground. The beams being connected by at least one pair of connecting rods, the connecting rods extending from one beam to the other while being inclined, from the upper beam to the lower beam, forwards in a forward direction of movement of the hoeing device. A connecting member is inserted between the frame and the deformable parallelogram.
