A rotary mowing attachment 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 mowing drums, which are attached rotatably under the transverse support parallel to each other, and displaced from each other. At least one mowing drum is swingable about its adjacent mowing drum 180.degree. with respect to the axis of the adjacent mowing drum in such a way that its axis retains its angle to the ground. Thus the mowing drums have at least two configurations, in one of which all the mowing drums are side-by-side with an equal spacing between adjacent drums of a width which is much smaller than the width of a mowing drum, and in another in which there is at least one comparatively large gap between two adjacent mowing drums substantially equal in width to the diameter of a mowing drum.
In a rotary mowing attachment for a tractor and the like comprising a transverse support attached to said tractor by a towing bar orientable at an acute angle to a travel direction of said rotary mowing attachment, a plurality of mowing drums attached under said transverse support parallel to each other so as to each be rotatable, said rotary mowing drum being offset from each other in said travel direction of said rotary mowing attachment, the work zones of said rotary mowing drums overlapping, the improvement which comprises means for swinging at least one of said mowing drums through substantially 180.degree. around an upright axis of a neighboring mowing drum with the angle of an axis of the swingable mowing drum with respect to the ground maintained unchanged.
