Hydraulic variable width reversible plough is an upgraded heavy-duty farm tillage machine matched with tractor three-point hitch system. It integrates hydraulic 180° turnover function and hydraulic width adjustment function. Different from ordinary fixed-width reversible ploughs, this model can remotely adjust the total working width via hydraulic control during operation. The plough body can flip bidirectionally at the end of the field to realize back-and-forth soil turning without large-radius turning of tractors. This equipment is widely used in large farmland, grain planting bases, agricultural cooperatives and land consolidation projects. It can complete deep tillage, soil inversion, straw burial and weed suppression in one operation. It is suitable for dry land, loam soil, sandy soil and moderately sticky soil. It can adapt to different agronomic requirements and variable plot conditions, effectively solve the limitation of fixed working width of traditional ploughs, reduce repeated land preparation and improve the uniformity of ploughing quality.

1. Dual hydraulic control system, reversible and variable width. The hydraulic circuit controls plough body 180° reversal and working width adjustment. Operators can adjust the total tillage width directly from the tractor cab, no need to stop working or manually disassemble and reposition plough bodies. Flexible adjustment adapts to different row spacing and plot width.
2. Heavy-duty reinforced frame structure. The main beam adopts thickened high-strength rectangular steel pipe, which is resistant to torsion and bending under heavy deep plough load. The plough share and mouldboard are made of boron steel with quenching treatment, high hardness and excellent wear resistance.
3. Graded mouldboard plough body design. The plough surface has good self-cleaning performance, less mud adhesion when working in sticky soil. The soil turning and furrow inversion effect is neat, straw and crop residues are fully buried under the topsoil, and soil clods are broken evenly.
4. Safety protection mechanism. Each plough leg is equipped with safety shear bolt. When encountering underground stones, tree roots and hard obstacles, the shear bolt breaks preferentially to protect the plough frame and plough body from permanent deformation or damage.
5. Standard three-point hitch connection. Universal mounting structure matches high-horsepower wheeled tractors. Installation and disassembly are fast, simple commissioning, stable connection during high-speed operation.
6. Adjustable tillage depth. Equipped with depth control wheel, the working depth can be adjusted continuously according to agronomic standards to meet different requirements of shallow tillage and deep tillage.

Soil inversion and deep tillage: Turn over topsoil, break the compacted plough pan, improve soil aeration, water permeability and soil water storage capacity, optimize soil structure.

Crop residue burying: Bury straw and weeds deep into soil to accelerate organic matter decomposition, increase soil fertility and reduce the overwintering population of pests.

Hydraulic variable width operation: Adjust working width freely according to plot size, tractor power and planting mode, improve the adaptability of tillage operation.

High-quality land preparation: Bidirectional ploughing eliminates unilateral ridges and furrows left by single-sided plough. The ground after ploughing is flat, reducing the workload of subsequent harrowing and sowing.

Multi-terrain adaptability: Suitable for large flat fields and irregular plots. It can work continuously on dry farmland, loam and sandy soil.

Flexible working width adjustment. Compared with conventional fixed-width reversible plough, this model supports hydraulic width adjustment without shutdown. Users can match the working width with tractor power and field condition in real time, avoiding overload of tractor or insufficient ploughing coverage.

Superior ploughing quality. Bidirectional turning design leaves no furrows on the field surface. The straw burying rate is high, soil inversion is complete. The variable width function ensures consistent tillage effect on irregular plots.

Strong structural durability. Heavy-duty thickened beam and heat-treated boron steel wearing parts greatly extend service life. The shear bolt protection reduces maintenance cost and downtime caused by underground obstacles.

High operation efficiency. Bidirectional ploughing reduces turning time at field ends. Hydraulic width adjustment saves manual adjustment time. The overall working efficiency is improved by more than 35% compared with fixed-width reversible plough.

Wide market compatibility. It matches mainstream high-horsepower tractors. It is ideal equipment for large farms and agricultural service companies. The machine has strong universality of spare parts, convenient after-sales maintenance.

Good economic return. It can complete deep tillage and straw returning in one pass, reduce repeated operation and fuel consumption. One machine can cope with multiple field conditions and agronomic schemes, lowering the total investment of agricultural machinery.
