In the controller, the coupling of a valve with the operating device of the loader harvester's cross-cutting device, and with a tilting mechanism of a tilting frame, is arranged to operate in conjunction with the cutting device and felling so that the gripping devices 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.
