Control arrangement for control of overcharging agricultural crop from a harvester to a transport vehicle

The invention relates to a control arrangement for controlling the overcharging agricultural crop from a harvesting machine (10) on a a loading container (18, 18 ') complete transport vehicle (12, 12'), with a first transmitting means (148) for electromagnetic waves in the radio frequency range cooperating and to the first transmitting means (148), first receiving means (150) which is connected to a control means (112) operable, based on the signals of the first receiving means (152) the position of the discharge end of a discharge device (40) to control automatically. It is proposed that the first receiving means (150) is arranged to detect the propagation time of electromagnetic waves between said first transmission means (148) and the first receiving device (150).
