ABSTRACT OF THE DISCLOSURE A reversible plough comprising a headstock adapted for connection to a tractor and having bearing means providing a reversing axis; a reversing spindle rotatably mounted in the bearing means along the axis; a plough frame secured to the reversing spindle for rotation therewith and for supporting left and right handed plough bodies; a hydraulic ram for rotating the reversing spindle to effect reversal of the plough frame; a stop member rotatable about the reversing spindle and having a pair of stops corresponding to right and left handed ploughing positions of the frame respectively and being adjustable in position relative to the member to enable pre- setting of the ploughing positions relatively to the headstock and an abutment fixed to the reversing spindle to rotate there- with whereby, upon rotation of the reversing spindle by the ram to effect reversal of the plough frame from one to the other of the ploughing positions, the abutment engages the member, the member thereafter rotating with the reversing spindle until the stop corresponding with the other ploughing position engages the headstock to prevent further rotation of the plough frame and to locate the plough frame in the other ploughing position as pre-set.
