RoTeC Control coulter – The universally-usable single disc coulter

RoTeC coulters are maintenance-free and work very reliably, even where large amounts of straw and plant residues prevail. The sowing disc and a furrow former create the seed furrow profile and provide optimum seed placement into the soil. The Control 10 depth guidance disc or the Control 25 depth guidance roller prevent the soil from sticking to the sowing disc, thereby ensuring that the pre-selected sowing depth is precisely maintained.

Row spacings of 12.5 cm and 15 cm can be chosen.


Advantages of the RoTeC coulter 

  • High-performance single disc coulter for wet and cohesive soil types 
  • High level of self-cleaning through the depth guidance roller 
  • Decoupling of coulter guidance and reconsolidation 
  • Up to 35 kg additional coulter pressure

Ingenious independent depth control of coulter and following harrow

One of the unbeatable advantages of the RoTeC coulter is that there is no connection between depth control and the reconsolidation system. This means that the coulter is raised only once when passing a stone. Furthermore, the coulter and harrow pressure can be adjusted independently of each other. This very even and accurately controlled way of guiding the RoTeC coulter is ensured by the Control 10 depth guidance disc with its 10 mm wide contact area or the Control 25 depth guidance roller with its 25 mm wide contact area mounted directly on the coulter.

The basic setting of the sowing depth is carried out directly on the coulter in 3 steps without the need for tools.

Coulter pressure adjustment

RoTeC coulters are operated with a coulter pressure of up to 35 kg. In this case the actual effective coulter pressure is comparatively higher with AMAZONE, because the pressure is not distributed between the coulter and the following press roller, but acts solely on the coulter. When sowing rape, or early sowing in dry conditions, working with less coulter pressure is possible without any problem.

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.
