Abstract
A sowing device having a travelling framework () is described, which comprises a storage roll () for a seed strip () equipped with individual grains () of a seed, and an unwinding unit () for the seed strip () drivable as a function of the travel distance. To ensure a precise deposit of the seed grains (), it is suggested that a sensor () for the individual grains () in the seed strip () be provided in the area of the seed strip section () between the unwinding unit () and a ground-proximal deflection roll (), and a control unit (), connected on one hand to the sensor () and on the other hand to a travel distance encoder (), activate the drive () of the unwinding unit () as a function of the difference between the actual location of the seed grains () detected by the sensor () and a setpoint location predefinable with the aid of the travel distance encoder ().
