The seed drill has supporting wheels (26) which are hingeable to a transport position. To divide the weight of the machine to all wheels of the tractor, there may be a large hopper (43) supported on the front side of the tractor. The said material is then transported by an air stream from the large hopper (43) to the seed drill behind the tractor. If no further machine is installed, the seed drill may be fixed to the tractor through a trestle (31).</p> |
