КРН 4.

Technical analysis of the KRN 4. inter-row cultivator

The efficiency of inter-row cultivation is defined by the rigidity of the parallelogram linkage and the accuracy of the working tools' penetration depth. The KRN 4. model provides a reliable solution for row crops, where stability is the primary factor. Unlike lightweight designs, this unit features a reinforced tool bar that absorbs vibrations during high-speed operation, preventing the sweeps from wandering off the row line.

Key components and functional design

• Parallelogram mechanism: Provides accurate ground contour following. The hinge points are equipped with grease nipples to keep play at a minimum, which is critical for maintaining a consistent operating depth when the tractor crosses uneven terrain.
• Working tools: The standard setup includes sweeps designed for cutting weed roots and aerating the soil. The pitch angle adjustment is managed through robust pressure screws, allowing the operator to adapt quickly to varying soil compaction levels.
• Structural integrity: The frame is engineered for heavy-duty service. The geometry of the transport mechanism minimizes stress on the tractor's hydraulic system by optimizing the center of gravity.

In practice, the KRN 4. is essential for three primary objectives: breaking the soil crust to retain moisture, controlling weed growth during early vegetative stages, and applying fertilizers when equipped with the optional system. The structural durability of the frame allows for the integration of additional attachments, making the cultivator a versatile asset for modern field management.
