Demetra ДМТ Discs: Precision Tillage for Moisture Conservation

The Demetra ДМТ series of disc harrows represents a strategic balance for farmers needing intensive soil cultivation without the soil compaction typical of heavier, overkill equipment. Unlike ultra-heavy discers that often pulverize topsoil, the ДМТ design focuses on creating a crumbly, stable soil structure essential for moisture retention.

Engineering and Performance

• Proprietary Disc Profile: The working geometry ensures a consistent angle of attack, allowing effective soil penetration up to 15-18 cm, even in fields with heavy crop residue.
• Damping System: Integrated shock absorbers on the disc gangs mitigate stress from rocks or compacted layers, protecting the frame from fatigue and structural damage.
• Frame Geometry: The weight distribution across the working width is optimized to reduce vertical bounce and vibration, allowing for stable operation at speeds up to 12 km/h.

Pros and Cons

The standout feature of this series is the predictability of the seedbed. While some harrows tend to "float" out of dry, compacted soil, the ДМТ maintains its set depth consistently, minimizing field ridging and ensuring a level surface that simplifies subsequent planting passes.

As with mid-range agricultural equipment, maintenance of the hub assemblies is the key to longevity. On highly abrasive or stony fields, the bearing points require consistent daily inspection and greasing to avoid premature wear. This is a maintenance-intensive machine, but one that rewards the operator with precise cultivation results.

Target Operations

The ДМТ lineup is best suited for medium-to-large scale operations running tractors between 150 and 250 horsepower. It is a workhorse for farmers shifting toward minimum-tillage practices who cannot afford to sacrifice speed or fuel efficiency. If your focus is on uniform residue incorporation and consistent depth control, the Demetra ДМТ offers a reliable return on investment.
