Abstract

A sowing device having a travelling framework (2) is described, which comprises a storage roll (3) for a seed strip (4) equipped with individual grains (5) of a seed, and an unwinding unit (6) for the seed strip (4) drivable as a function of the travel distance. To ensure a precise deposit of the seed grains (5), it is suggested that a sensor (15) for the individual grains (5) in the seed strip (4) be provided in the area of the seed strip section (14) between the unwinding unit (6) and a ground-proximal deflection roll (8), and a control unit (16), connected on one hand to the sensor (15) and on the other hand to a travel distance encoder (18), activate the drive (17) of the unwinding unit (6) as a function of the difference between the actual location of the seed grains (5) detected by the sensor (15) and a setpoint location predefinable with the aid of the travel distance encoder (18).
