The invention relates to an anti-drift device for harrows, and particularly for harrows with sets of disks arranged in a perfect X. This device includes a plane disk 1 of large diameter, of the order of magnitude of the disks of the agricultural sets, or slightly greater, mounted so that it can rotate freely axially in the elastic suspension on the chassis of the harrow, arranged in a substantially central position and in the median longitudinal plane of the harrow, so that it penetrates the soil while running at a substantially constant depth during work, the said elastic suspension 3 allowing the disk to retract vertically in the face of an obstacle or uneveness of the ground, but resisting transverse forces so as to keep the harrow in line during the work. <IMAGE>
