ABSTRACT An agricultural roller has two or more pivotably connected sections arranged side by side. A central frame has a tow- ing bar pivotably connected to the central frame. The rol- ler has roller sections (4, 6) on either side of the cen- tral frame (8) and transport wheels (15, 16), which are settable between an inactive position above the ground in the work position of the roller and a transport position where the roller means are lifted up from the ground and swung towards each other to achieve a small transport width. The two side sections (4, 6) situated closest the central frame (8) carry the transport wheels connected to the sec- tion frames, and between the sections there are pivot joints (17, 18) implemented such that the sections can ad- just themselves to irregularities in the ground in the working position of the roller. A hydraulic cylinder (21) is arranged between -the towing bar (2) and central frame (8), and can swing the central frame and the roller sections (4, 5,6) connected thereto about 90° about a pivoting axis trans- verse the driving direction to an "on edge" or intermediate position,where the roller rests on the trans- port wheels (15, 16). By driving the tractor forwards the side sections (4, 6) are caused to swing towards each other into the transport position.
