Abstract
An agricultural machine comprises two harrows 1, 2 positioned on the same axis perpendicular to the direction of advance of the machine. A supporting frame 23 connects these harrows, each of which is able to rotate about a pivot 40, 45 to allow it to be lifted so that the machine can be made compact during road travel or during movement over the field. The transverse dimensions of the machines are very narrow because the two pivots are very close together, coinciding with the arms 43 of the spiders of the universal joints that transmit the power from the central gearbox. An initial offset of the arms 43 of the spiders is necessary. When the harrows are raised by rotation, an automatic offset between the two arms 43 of the spiders is brought about, in line with the pivots 40, 45. <IMAGE>
