A ballast plough (1) consists of a machine frame (6) supported on on-track undercarriages (2), with which is associated a centre plough (5) which is vertically adjustable by means of drives and on each longitudinal side of the machine a vertically adjustable shoulder plough (8) having a plough blade (20) which may be brought into contact with ballast. The said shoulder plough is provided with an articulation point (13) and a telescopically extendable carrier frame (12) extending perpendicularly to the longitudinal direction of the machine. The articulation point (13) is situated in each case - viewed in the transverse direction of the machine - on the longitudinal side of the machine which is further away from the associated plough blade (20) of the shoulder plough (8). The plough blade (20) is mounted for pivoting about an axis (21) extending in the longitudinal direction of the machine and is connected to a shoulder angle adjustment drive (15).
