CMN Straw Harrow – Efficient Straw Distribution and Weed Seed Activation Exhibitor: CMN Maskintec A/S (Denmark) Hall 5 – Stand 18The CMN Straw Harrow is the efficient solution for stimulating weed seed germination, ensuring even straw distribution, and incorporating organic residues into the upper soil layer after harvest.
At the same time, the machine helps reduce slug populations by drying the soil surface and improving decomposition.Design and Function
The CMN Straw Harrow is available as a trailed model (up to 16 m working width) or as a mounted 3-point version – ideal for all farm sizes and soil conditions.
It can be equipped either with fixed tines or with hydraulically adjustable tine angles, allowing precise adaptation to varying soil and residue conditions.Main specifications: Row spacing: 50 cm / effective spacing: 10 cm Tine diameter: Ø 16 mm Free tine height: 65 cm Double-wound springs for optimal vibration and stabilityThis combination enables the Straw Harrow to work clog-free even with large amounts of organic material, ensuring even mixing and surface activation.Vario Model – Hydraulically Adjustable Tine Angle
The Vario model features straight 16 mm tines whose angle can be hydraulically adjusted from 90° (vertical) to 45° (rearward).
Thanks to the serial hydraulic control, each tine applies equal ground pressure, providing uniform working depth and consistent performance across the entire width.Optimal Use and Agronomic Benefits
The best decomposition effect is achieved when the Straw Harrow is used immediately after the combine harvester, as microbial activity in the soil is highest at this time.
This ensures rapid straw composting, improved soil aeration, and targeted germination of weed seeds for subsequent mechanical weed control.Available Working Widths
Available in 3 m, 6 m, 8 m, 12 m, and 16 m working widths – suitable for various tractor classes and field conditions.New for 2025 – Vario Model with Stubble Rollers
The CMN Vario Straw Harrow is now available with hydraulically controlled stubble rollers, allowing a two-stage working process: Distribution and activation of straw and weed seeds Crushing and incorporation of stubble for faster decompositionThe hydraulic roller control enables precise adjustment of contact pressure between tines and rollers, ensuring optimal performance under all soil conditions.CMN Maskintec A/S – Innovative Danish manufacturer of machinery for mechanical weed control and soil cultivation (since 1988)
