<p>A traction and control mechanism for work implements such as an agricultural roller intended to be pulled by a tractor or similar means, comprising at least two implement sections (2, 3) attached to swivel arms (4, 5), which can be slewed in the horizontal plane between a transport position in which all sections (1, 2, 3) are one behind the other in the direction of pull and a working position in which the side sections (2, 3) are slewed out at either side of the implement's centre line. The swivel arms consist in a long swivel arm (4) and a short swivel (5), each swivel arm being provided with a fixed implement holder (6). The implement holder (6) of the long swivel arm (4) is behind the implement holder (6) of the short swivel arm (5) when the swivel arms (4, 5) are slewed backward towards the direction of pull, towards one another and parallel to the centre line of the implement. It is advantageous for the long swivel arm (4) to be capable of being slewed about a main spindle (7) linked with a traction device (15) which is connected to the tractor. The short swivel arm (5) can be slewed about a pivot spindle (8) linking the swivel arms (4, 5). The distance between the main spindle (7) and implement holder (6) of the respective swivel arms (4, 5) is the same when the swivel arms (4, 5) are slewed out to the working position.</p> |
