Avant-Säeinheit mit TwinTeC-Schar (1) TwinTeC-Schar_76_d1_190708

Avant seed rail with TwinTeC coulter

The high-performance double disc coulter, clean and precise seed placement

Advantages of the double disc coulter:

  • Extremely precise seed placement thanks to the extremely smooth and clean running of the double disc coulter
  • Consistent sowing depth thanks to the high constant coulter pressure of up to 60 kg
  • Optimum contour following due to the coulter guidance in the parallelogram
  • Simple central seed depth adjustment
  • Effective sowing even under difficult conditions thanks to a high through passage and low angle of attack of the discs



  1. Adjustable harrow: the angle of attack is adjusted according to the degree of straw residue present.
  2. Perfect parallelogram with the top link for infinitely variable and precise adjustment of the sowing depth from 0 to 6 cm.
  3. Centralised, 100% independent adjustment of the placement depth and coulter pressure.
  4. TwinTeC coulters mounted on rubber elements for shock absorption and central adaptation of the coulter pressure from 0 to 60 kg.
  5. Protective front panel
  6. Removable shims to compensate for disc wear.
  7. Discs fastened at 5 points with recessed Torx screws. No wear on the fixing discs.
  8. Maintenance-free bearings. No lubrication points on maintenance-free coulter.
  9. Double disc ∅ 340 mm, angle of 10°, row spacing 12.5 or 15 cm. 
  10. Internal scraper – as an HD variant.
  11. Depth control and press rollers with 50 or 65 mm width (scrapers optional).

Simple and central adjustment of the depth control

The sowing depth of the TwinTeC double disc coulter can be centrally adjusted on the coulter frame. A depth guidance roller provides exact depth control behind every TwinTeC coulter, so that the sowing depth of each individual TwinTeC coulter is maintained. Thanks to the large coulter clearance of 195 mm and the connection to the depth guidance roller via the top guided roller carrier, sufficient space remains so that blockage-free operation is maintained. Due to the sowing discs’ low angle of attack of 10°, a superb passage of material is ensured even at high forward speeds and in copious amounts of crop residues. There is a choice of two different depth guidance rollers. The Control 50 mm depth guidance roller has a large passage and is suited especially for heavy soils that have a good carrying ability. On the other hand, the Control 65 mm depth guidance roller offers a higher carrying capacity, which is ideal for lighter locations.

Removable Avant seed rail

The rotary cultivator and the Avant seed rail can be very easily separated to allow the rotary cultivator to be flexibly used elsewhere. Despite a working width of 6 m, the complete seed rail can be dismantled in just 30 minutes. The Avant with a 3 m or 4 m working width can be converted for solo operation in approx. 5 minutes thanks to QuickLink.

Coulter harrow on the TwinTeC coulter

As an option, every TwinTeC coulter can be equipped with a directly suspended harrow. The coulter harrow creates additional loose soil over the furrow.


The benefits:

  • Depth guidance with sprung harrow carrier
  • Adjustable in 7 steps up to 150 mm 
  • Adjustable intensity in 3 stages: 30°, 45°, 60°

Coulter pressure adjustment

Since all the coulters are suspended in a parallel guided frame, central and stepless adjustment of the coulter pressure is possible. For example, the coulter pressure in the area of the tractor wheels can be increased by a further 6 kg by means of additional tensioning springs.

Hydraulic coulter pressure setting with coulter lift of up to 145 mm

The hydraulic coulter pressure adjustment enables the coulter pressure to be comfortably adjusted from the tractor cab. The coulter can also be lifted by up to 145 mm. The coulter lift is an extremely useful option for working in field corners.

Avant seed rail with RoTeC coulter

The universal single-disc coulter, reliable and precise right up to the limit

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. The row spacing is 12.5 cm. The RoTeC coulter system: tried and tested 1,500,000 times over!


  • 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


  1. Precise depth adjustment from 1 cm to 6 cm.
  2. Reinforced support arm with a coulter pressure of up to 35 kg. Central coulter pressure adjustment.
  3. Choice of 25 mm or 10 mm “Control” combined depth control and cleaning roller for even seed placement.
  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.

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 takes place without tools and in 3 steps, directly on the coulter.

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.
