Велес-Агро ПНВБ-3-40+

Engineering design of the Veles-Agro PNVB-3-40+

The Veles-Agro PNVB-3-40+ semi-mounted reversible plow is built for heavy-duty soil tillage. The core of its design is a high-strength steel modular frame, engineered to absorb torsional stresses while working in demanding field conditions. The profile thickness is optimized to maintain structural integrity at operating speeds of up to 10 km/h, ensuring high output without compromising the durability of the metal parts.

Work components and durability

The plow utilizes semi-helical moldboards designed to provide superior soil inversion and crop residue burial, even in high-moisture conditions. The geometry of the moldboard reduces draft resistance, keeping fuel consumption efficient for tractors in the 105–130 hp range. A critical technical detail is the use of high-grade wear-resistant steel for shares and chisels, which maintains their sharpness and shape over long cycles, ensuring consistent furrow depth.

Reversing mechanism and stability

The hydraulic reversing system is powered by a robust cylinder, allowing for smooth, shock-free transitions during operation. The semi-mounted configuration, supported by a depth-control wheel, balances the weight across the tractor’s three-point hitch, reducing strain on the tractor hydraulics and improving maneuverability at headlands.

• Shear-bolt protection: Each shank is equipped with a shear-bolt mechanism that protects the frame from damage upon hitting hidden rocks or heavy obstacles.
• Versatility: The adjustable cutting width allows operators to match the implement load precisely to soil resistance and engine power.
• Ease of maintenance: The modular layout ensures that individual components can be inspected or replaced quickly in the field.

The PNVB-3-40+ is a practical solution for farmers who prioritize classic moldboard plowing combined with long-term mechanical reliability and ease of service.
