The reversible plow is a core tillage machine used with tractors. It uses a double-acting distributor to control the lifting and 180-degree reversal of the plow, enabling bidirectional alternating operation. Its core structure includes a suspension frame, hydraulic reversing mechanism, screw-adjustable land wheel, plow frame, and plow body. It is suitable for 50-100kW diesel tractors, with a working width of 90-150 cm and a plowing depth of 15-35 cm. Typical models, such as the 235 reversible three-furrow plow, weigh 400-590 kg and are suitable for medium-sized tractors; heavy-duty models, such as the 330, use a double-layer plow wall structure, weigh over 1000 kg, and require ≥88kW power support.

Technical Characteristics and Advantages

Bidirectional Hydraulic Reversal

The plow frame is vertically reversed by a hydraulic cylinder, taking ≤30 seconds per reversal, saving time and fuel.

The heavy-weight depth-limiting wheel automatically changes position, ensuring constant plowing depth with an adjustment accuracy of ±1.5 cm.

Modular Design and Efficient Maintenance

Easily damaged parts such as plow points and plow legs are assembled with bolts and can be replaced individually, reducing maintenance costs by over 60%.

The plowshare is made of 65Mn high-manganese steel through a heat treatment process. The vertically inclined plow point forms a 45° angle with the traction direction, reducing soil resistance and significantly improving soil turning and breaking.

Adaptability to Multiple Scenarios

Equipped with a three-stage width adjustment mechanism (21°/24°/28°), the plowing width can be adjusted according to soil resistance, increasing efficiency by 30%.

The hydraulic system reduces the turning radius at the field edges to 4 meters, and the lateral tilt angle adaptability during hillside operation reaches 15°, breaking up the plow sole and increasing the plowing depth from 18 cm to 25 cm.

Environmental Protection and Increased Production

Buries surface weeds 20 cm below the surface, inhibiting weed growth, reducing soil bulk density by 0.3 g/cm³, and increasing nutrient and water content.

The surface is leveled to ±3 cm after plowing, with good coverage, which is beneficial for deep burial and decomposition of crop residues and weeds to improve soil fertility.
