Abstract:
1. Assembly for the precision drilling of seed grains, comprising: a drilling machine with at least one row unit which is assigned a drive set up for instigating delivery of a seed grain into a furrow, and a control system, which is connected to a position-determining system, to a memory unit for storing delivery positions of seed grains, to the drive of the row unit and to a seed material sensor for detecting an actual delivery position of the seed grains and which can be operated to control the drive based on signals from the position-determining system, the memory unit and the seed material sensor so that the seed grains are deposited successively at the delivery positions, wherein the seed material sensor is adapted to detect the final position of the seed grain in the furrow; and wherein the control system can be operated to evaluate on the basis of the signals from the seed material sensor a time stagger (Δt) between activation of the drive and the moment the seed grain reaches its final position in the furrow and to take this into consideration together with a current machine forward drive speed (v) when controlling the drive.
