Demetra КРН-5.

Engineering Review: Demetra КРН-5.6

The efficiency of inter-row cultivation for row crops depends on the rigidity of the cultivator's frame and the precision of the working tools' penetration. The Demetra КРН-5.6 is designed for intensive farming, where frame stability is critical during operations at speeds up to 10 km/h. The backbone of the structure is a heavy-duty structural steel beam with an increased cross-section, which prevents section twisting even when navigating through compacted soil patches.

Sectional Assembly: Terrain Following

A key advantage of this model is its parallelogram suspension system. Unlike rigid mounting schemes, this configuration ensures independent ground following for each working tool. Practically, this ensures a consistent weed-cutting depth even on uneven micro-relief, preventing damage to the root systems of the cash crops.

• Working Tools: Equipped with wear-resistant sweeps featuring an optimized attack angle, effectively reducing draft force and minimizing tractor fuel consumption.
• Adjustment System: Depth control and width adjustment mechanisms utilize quick-release locks, allowing operators to reconfigure the unit for various crops (sunflower, corn) in minimal time.
• Protection Shields: Equipped with side deflectors that shield young seedlings from soil burial during high-intensity hilling operations.

Implementing the Demetra КРН-5.6 allows farmers to transition from blanket chemical weed control to mechanical intervention. This approach not only lowers production costs but also promotes soil aeration, significantly improving moisture absorption during critical crop growth stages.
