Eco-Friendly and Biodiversity-Focused

The CMN Kvik-Killer is engineered with environmental sustainability in mind. Its slow-moving rotor protects biodiversity by sparing earthworms and other beneficial organisms, while effectively removing tough weeds like couch grass, thistles, and mugwort.

Safety and Durability You Can Rely On

  • Automatic Clutches on all rotors protect against overload.
  • Stone Protection on each rotor tooth prevents damage.
  • Free Replacement Policy: Broken tooth? We’ll replace it at no cost!

Models and Applications

The CMN Kvik-Killer is available in working widths of 2, 3, 4, and 6 meters, with or without a stubble harrow. Choose the model that fits your needs:

  • Trailed Models: Ideal for larger operations with better clearance between harrow tines.
  • Mounted Models: Flexible and easy to maneuver.

For some tasks, the rotor can be used alone, provided the soil is pre-processed with a stubble harrow.

How the CMN Kvik-Killer Works

  1. Soil Loosening: The stubble harrow’s powerful tines with 48 cm-wide wing shares loosen the soil.
  2. Gentle Lifting: The rotor gently lifts organic material to the surface for drying.
  3. Adjustable Working Depth: Depths of 8–14 cm, depending on soil type, ensure optimal root control.

The Benefits of CMN Kvik-Killer

  • Reduce Yield Loss: Prevent yield losses of up to 50% caused by couch grass.
  • Minimize Nitrogen Leaching: Promote soil health by retaining nitrogen and enhancing carbon content.
  • Achieve Up to 80% Weed Reduction after the first treatment.

Recommended Weed Control Strategies

  • After Harvest: Perform a full pass to control weeds effectively.
  • Before Plowing: Repeat the process to ensure weeds don’t survive the winter.

Efficient Grassland Renovation

The CMN Kvik-Killer excels in breaking down old grass swards during the renovation of grasslands and seed fields, improving soil conditions and preparing the land for new crops.

Meaning of Couch Grass

Couch grass is a greedy plant that competes with crops for light, water, and nutrients. It can reduce yields by 30–50%. The table below shows yield losses in spring barley at various levels of couch grass infestation. Source: National Centre for Crop Production.

Effective Weed Control with the CMN Kvik-Killer

 

The combination of the slow-moving pickup system and the soil’s high density makes the CMN Kvik-Killer a highly efficient and gentle solution. The machine ensures that soil, stones, and beneficial organisms like earthworms pass easily beneath the pickup, while organic material such as weed roots is lifted and placed on the soil surface to dry or be collected.

 

Optimal Weed Control and Timing

 

To achieve the best results, weed control should begin immediately after harvest:

 

  1. First Pass: Perform a full cut to bring couch grass and other root weeds to the surface. This treatment eliminates up to 80% of root weeds.
  2. Cover Crops: Simultaneously sowing cover crops improves soil structure and reduces nitrogen leaching. Rapid decomposition of chopped straw increases soil carbon content while reducing working hours per hectare.

 

Preparation Before Plowing

 

Before plowing, an additional treatment with the CMN Kvik-Killer is recommended to:

 

  1. Incorporate cover crops and organic material into the soil.
  2. Expose any remaining weed roots that may have survived the winter.

 

These exposed weed roots can be buried deep at the bottom of the plow furrow using a properly adjusted front plow, preventing them from sprouting again. Proper sorting and adjustments are critical for successful root weed control.

 

CMN Kvik-Killer with Seeder: Two Solutions in One

 

For even greater efficiency in root weed control, the CMN Kvik-Killer can be equipped with a seeder. This combination allows you to manage weeds and establish a new crop in a single operation.

 

System Advantages:

 

  • Surface-Level Control: Weed seedlings and small roots in the topsoil layer (5–7 cm) are effectively removed. Any remaining roots are exposed during seeding and dry out.
  • Weather-Independent Results: With the CMN Kvik-Killer, you don’t need long dry periods to achieve effective results.

 

Long-Term Benefits of the CMN Kvik-Killer

 

With the CMN Kvik-Killer, you can:

 

  • Reduce the need for chemical weed control.
  • Promote a healthier soil structure with greater biodiversity.
  • Achieve efficient root weed control, ensuring better yields and long-term field productivity.
