<p>A rake provided with a frame (10) with vertical uprights (12, 13) on wheels (14, 15), in which the gathering arms (21, 22), each equipped with a plurality of rake wheels (23,24), are of unequal length, the longer arm (e.g. 21) being hinged to one of the vertical uprights in an intermediate point, so as to project beyond said frame (10). In operation, the arms (21, 22) are rotated about the intersections with the uprights (12,13), so as to form, in horizontal projection, a Y. With said arrangement, the first of the wheels (e.g. 23) of the longer arm (e.g. 21) surmounts the first rake wheel (e.g. 24) of the other arm (e.g. 22), in this way guaranteeing that all the material (grass or hay) to be gathered is effectively gathered.</p> |
