ABSTRACT REVERSIBLE PLOUGH A reversible plough has a headstock formed from upper and lower parts (7,3) hingedly connected about a transverse axis (9), the reversing spindle (17) being mounted in the lower headstock part (3) and carrying a crank arm (21) connected by a link (23) to the upper headstock part (7). As the reversing spindle is rotated, relative hinging movement between the two headstock parts causes the reversing spindle to tilt in a vertical plane, the load in said link (23) counterbalancing to a degree the offset centre of gravity of the plough frame and reducing the torque required to reverse the plough frame.
