A machine for digging moor peat comprises a frame (10), carrying power transmission equipment (13) to operate both an excavator disc (14), and a press (18) filled by the action of the disc (14). The press (18) includes a transfer screw rotary within a nozzle box (21) provided with nozzle openings for compressed product. In order to minimise blockage by woody material of these outlet nozzles the box (21) of the press is provided with a return pipe (20) for the peat mass, by-passing the zone of the nozzle openings, whereby a recirculation of a promotion of the peat mass is obtained, to promote a grinding action and thereby reduce the tendency to nozzle blockages. <IMAGE> |
