<p>This invention relates to a mowing machine for cutting grass or other crops, the machine being of the kind which is intended in use to be traversed over a standing crop by means of an agricultural tractor. In accordance with the invention and as shown in one example in the accompanying drawing, the mowing machine comprises a V-shaped frame lO arranged so that the apex of the vee will be foremost, having regard to the direction of travel, as the machine is traversed over the standing crop. Mounted on each of the arms ll and l2 of said frame are at least two cutting units in the form of drum-type rotatable cutters l6 and connected to each of said arms is a crop conditioning means comprising an apparatus l7 having a pair of doors which are each hinged about a vertical axis, the hinged edges being remote from each other so that the drums can be set in a position in which their inner, adjacent, edges also extend vertically but spaced from each other to form a gap or opening of variable widths through which the cut crop will in use be expelled, the two streams of cut crop so expelled from said pair of crop conditioning apparati converging to form a single swath.</p> |
