The hydraulic reversible plough is used along with the tractor. A twin dispenser controls the lifting and turning of the plough. The reversible plough includes a suspension frame, a turning oil cylinder, a non-return mechanism, a ground wheel mechanism, a plough frame and a plough body. The positive and negative plough bodies on the plough frame are vertically flipped by the extension and retraction of the piston rod in the oil cylinder, and are alternately changed to the working position. The ground wheel is a dual-purpose mechanism for adjusting the depth of cultivation with a screw. The product is applicable to the cultivated dry farmland in soil and sandy loam areas by virtue of its simple structure, large cultivation and adaptation range, high operating quality, good surface leveling, good soil crushing performance, small dead furrows, etc.
