Abstract
A windrower has a transverse support positioned at an angle to the travel direction of the apparatus and attached by a towing bar to a tractor and the like. The transverse support is provided with a plurality of crop-transfer drums, which are attached rotatably under the transverse support parallel to each other, and displaced from each other. At least one crop-transfer drum is swingable about its adjacent crop-transfer drum 180.degree. with respect to the axis of the adjacent crop-transfer drum in such a way that its axis retains its angle to the ground. Thus the crop-transfer drums have at least two configurations, in one of which all the crop-transfer drums are side-by-side with an equal spacing between adjacent drums of a width which is much smaller than the width of a crop-transfer drum, and in another in which there is at least one comparatively large gap between two adjacent crop-transfer drums substantially equal in width to the diameter of the crop-transfer drum.
