The subject of the invention is an operating coupling for controlling the operation of the gripping devices (4,5) of a loader harvester bulk handling device. In the operating coupling according to the invention, the coupling of the valve (18) with the operating device of the loader harvester's cross-cutting device, and with the tilting mechanism of the tilting frame, is arranged to operate in conjunction with the cutting device and felling so that the gripping devices (4 and 5) are normally in the closed position. The gripping devices are arranged, at least in the felling position, to always open when the guide bar or equivalent cutting device is operating or when the harvester head turns to the delimbing position, and to close immediately after the operation in question.
