ABSTRACT OF THE DISCLOSURE A plough for burying cable or pipe comprises at least two cutters laterally spaced apart, one being offset at an angle relative to the other for making two spaced apart cuts in a substrate to form a wedge of material. Means are provided for lifting and moving the wedge upwards and sideways to form a trench and for guiding the cable or pipe into the trench under the lifted wedge. The plough cuts an improved furrow shape, lifts the furrow slice through the minimum height in order to permit the cable or pipe to be inserted below it and allows the material to be replaced with minimum disturbence.
