An agricultural roller construction includes a tow-bar (12), a roller (1) comprising a plurality of swingable roller-sections (3-5), and transport wheels (15, 16) which in the working position of the roller are free from the ground, but which can be lowered to a roller-transport position by means of a hydraulic piston-cylinder device (13). The roller-sections include a main roller-section (4) provided with a section-frame (7) to which there is rigidly connected an arm (20) provided with a pivot device (14) for connection to the tow-bar (12). Also rigidly connected to the main-section frame (7) are carrier arms (17, 18) which carry the transport wheels (15, 16), and a further arm (19) which is provided with a pivot device (22) for connection to the hydraulic piston-cylinder device (13), this device also being connected to a pivot device (21). The roller is moved from its working position to its transport position, by swinging the roller through approximately 90 DEG in two movement stages. In the first of these movement stages, the shaft carrying the roll-pack (10) of the main roller section (4) forms the pivot shaft about which pivotal movement takes place until the transport wheels (15, 16) rest on the ground. The shafts of the transport wheels (15, 16) then form pivot shafts until the roller has been swung free from the ground to its transport position. The side roller-sections can then be swung in manually. |
