Machinery to plough land, having a moderately-even surface. The heavy engine is not required to move up and down the field with the ploughs, but is stationary whilst they are working from the hedge on each side up to the engine, when it is advanced the width of the part ploughed each trip. These ploughs are made to travel at five miles per hour.
