Inter-row weeding cultivator KRN5.6 Grand Max ROW CONTROL Ferti КРН-5,6 (rigid frame, with fertilizer application system)
Grand Max ROW CONTROL Ferti КРН-5,6 is a professional inter-row cultivator built on a rigid (solid beam) frame with an integrated liquid fertilizer application system (UAN, liquid fertilizers). It is designed for intensive farming, precise nutrient placement, and efficient mechanical soil cultivation.
This model combines high structural strength, operational stability, and advanced functionality, allowing multiple operations in a single pass: inter-row cultivation, weed control, and fertilizer application.
Key feature: rigid frame + integrated fertilizer application system
Unlike folding models, this cultivator is built on a solid rigid frame, providing critical advantages:
✔ maximum structural rigidity
✔ no play or deformation under load
✔ consistent geometry across the full working width
✔ precise depth control
✔ increased reliability on heavy soils
✔ reduced vibration during operation
The rigid frame is especially effective under intensive use, ensuring durability and consistent performance throughout the season.
Integrated fertilizer application system (FERTI)
The cultivator is equipped with a built-in liquid fertilizer system, mounted directly on the machine frame.
Key advantages:
✔ synchronized soil cultivation and fertilizer application (UAN/liquid fertilizers)
✔ no need for additional trailed or mounted equipment
✔ even weight distribution across the frame
✔ improved stability during operation
✔ reduced load on the tractor
✔ simple control and maintenance
Economic and agronomic efficiency
Using the Grand Max ROW CONTROL Ferti КРН-5,6 allows you to:
✔ perform multiple operations in one pass
✔ reduce fuel consumption by up to 30%
✔ minimize soil compaction
✔ apply fertilizers precisely in the root zone
✔ improve nutrient uptake efficiency
✔ increase crop yield
This is especially important for farms using precision agriculture and resource-saving technologies.
