ABSTRACT:
This invention provides a new method of ploughing in which the cut ridge is inverted in its own furrow. The plough for doing this consists of at least two upright main bodies (4) parallelly spaced and elongated in the ploughing direction. At the front portion the respective main body is provided with a ploughshare (6) extending in the horizontal plane. A mouldboard (7) designed in known manner extends from the rear edge of the share on the side of the one main body facing the second main body, while a second mouldboard (8) is arranged on the other main body on the side thereof facing the first main body. The second mouldboard (8) turns from an upright position connecting to the front portion of the main body (4) to a position where the lower edge of the mouldboard diverges from the main body at an even level while the upper edge of the plate (8) approaches that level.
