RoTeC Control coulter – The universally-usable single disc coulter

Goes right up to the limit of practical operation and placement: RoTeC Control coulters are maintenance-free and work extremely well yet with little wear and tear. Even where large amounts of straw and trash prevail they won’t block up. The combination of the sowing disc on the one side and the furrow former on the other create the perfect seed furrow and optimum seed control. The elastic polyurethane disc also helps to create the seed furrow, accurately controls the pre-set sowing depth and prevents soil from sticking to the sowing discs.


Quality and reliability throughout:

  • Coulter discs made from high grade Boron steel for an even more prolonged service life
  • Wear-resistant and self-cleaning Control 10 depth guidance discs and Control 25 depth guidance rollers for the exact adjustment of the placement depth
  • Decoupling coulter guidance and reconsolidation for a smoother coulter run and a universal response to the weather conditions


The maintenance-free RoTeC pro single disc coulter
1. Tool-free adjustment of sowing depth in 3 steps.
2. Reinforced support arm with a coulter pressure of up to 35 kg. Central coulter pressure adjustment.
3. “Control" 25 mm or 10 mm depth control and cleaning roller for an even planting depth.
4. Furrow former for a clean profile seed furrow.
5. Seed guide tube up to the furrow former for even seed placement.
6. Sowing disc ∅ 320 mm made of boron steel, working angle of 7°, for smooth operation of the coulter.
7. Exact harrow for excellent seed coverage.

Depth guidance

One of the unbeatable advantages of the RoTeC Control single disc coulter is that it is uncoupled from the coulter guide and the reconsolidation system. This means that the coulter is raised only once when passing a stone. Furthermore, the coulter and roller pressure can be adjusted independently of each other. This very even and accurately controlled way of guiding the RoTeC Control single disc coulter is ensured by the Control 10 depth guidance roller with its 10 mm wide contact area or the Control 25 depth guidance roller with its 25 mm wide contact area directly at the coulter.

The basic setting of the sowing depth takes place without tools and in 3 steps, directly on the coulter. Detailed infinite adjustment then takes place via the coulter pressure.

Coulter pressure adjustment

The coulter pressure is infinitely adjustable, either mechanically or hydraulically, and is used for easy adjustment of the sowing depth, allowing for rapid adjustment to the corresponding soil conditions.

RoTeC Control coulters operate at a coulter pressure of up to 35 kg.

Exact harrow

The exact harrow is used to cover the open seed furrows and to even out the soil; it works reliably, even if there are large amounts of straw. With its individually pivoting harrow elements, the Exact harrow follows the undulations of the soil perfectly, ensuring an even seed coverage on soils either with or without straw.

The harrow pressure is mechanically adjusted with plug pins from a central position. During hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. Thus the harrow and coulter pressure can be simultaneously adjusted with a single control valve while driving to adjust to varying soils.

Pre-emergence markers

When creating tramlines, the marker discs automatically lower and mark where the tramline will be created. This means that the tramlines are visible prior to the seed emergence.

Roller harrow

The roller harrow additionally consolidates the soil above the seed furrow resulting in the optimum germination conditions. This is especially recommended for light, dry soils when sowing spring crops or rape. An undulating surface profile that reduces erosion is the result. The particular advantage is that the roller pressure can be set completely independently of the coulter pressure.

Harrow pressure adjustment

The roller harrow is centrally adjusted via a harrow adjuster with overload protection. Thus the intensity of the roller pressure can also be very flexible adjusted for the roller harrow and the pressure rollers can also be completely switched off. Thus the pressure rollers can also be completely lifted under wet conditions, for example for seed placement in late autumn. The drag tine harrow can be accurately adjusted via a hole pattern.
