Reece, A R

This patent describes a plough for burying cable or pipe which plough comprises: a plough body having fixed thereto at least a first and second cutter offset to each other so as to make two spaced apart cuts in a substrate to form a wedge of material and the second cutter being able to move laterally with respect to the first cutter. The first cutter comprises a substantially vertical portion having a substantially horizontal cutting edge projecting from its lower extremity there being an inclined plane of substantially the same width as the substantially horizontal cutting edge rising upwards and to the rear of the cutting edge. The width is sufficient to lift the wedge of material upwards and sideways to form a trench there being a passage through the plough body down which the cable or pipe is guided into the trench.
