Abstract of the Disclosure The present invention relates to a peat machine for connection to a tractor or a corresponding power source. The piece peat machine is provided with a digging means for digging peat and a pressure screw for digged peat. In order to improve the production capacity and to reduce the power demand, the pressure screw is conically shaped so that its diameter diminishes towards the outlet nozzles. In addition, the thread of the pressure screw is, at the end facing the digging means, substantially at right angles to the shaft of the screw or inclined forwards towards the outlet nozzles. At the outlet nozzles, the thread is inclined backwards towards the digging means. (Figure 2)
