Abstract: A controller for controlling the operation of gripping devices of a loader harvester bulk handling device. 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.

Abstract: The subject of the invention is a grapple harvester which is equipped with a felling and cutting device (14), a feeder (12) and delimbing devices (9, 10, 11, 13). The grapple harvester according to the invention is equipped with a bulk handling device (4) which is arranged to grip together several trees, which are usually gathered one by one and, preferably, whilst in the vertical position, for cutting by the grapple harvester.

Abstract: 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.
