WS suffolk coulter

The robust and precise, plough-based coulter for the Cataya Special

The WS Suffolk coulter is particularly well-suited to seeding after the plough or if there is only a little straw, for example, after harvesting oil seed rape or turnips. The cast material in the coulter point has an exceptionally long service life. Worn coulter points can be replaced by releasing just a single screw in the case of large-scale operations with particularly aggressive soils.

The 3-row layout and the large coulter stagger prevent blockages in the coulter area. A funnel in the coulter guides the seed precisely behind the coulter tip. The back-up flap prevents the coulter outlet from being blocked when the machine is set down.

RoTeC-Control-Schar (Cataya)

RoTeC coulter – The universal 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

The maintenance-free RoTeC single disc coulter

1. Precise working 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. “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.

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 the coulter guidance and the reconsolidation system. This means that the coulter is raised just once when going over 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 3-stage, basic setting of the sowing depth is carried out directly on the coulter without the need for tools.

Coulter pressure adjustment

RoTeC Control coulters operate at 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. 

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

Simple setting of the placement depth on the right and left at the rear of the Cataya Special
In order to ensure that the placement depth of each individual TwinTeC special coulter is retained, there is a Control 50 depth guidance roller behind each double disc coulter to ensure precise depth control. Setting of the placement depth is carried out by two spindles on the right and left around the back of the Cataya Special. The placement depth can be infinitely-variably adjusted in each case, depending on the position of the depth guidance roller.

Infinitely-variable setting range: 

  • Lower position of depth guidance roller: 1 to 4.5 cm 
  • Upper position of depth guidance roller: 2.5 to 6 cm

Setting the coulter pressure is carried out centrally via a spindle in the middle at the back of the Cataya Special.

TwinTeC coulter – The high-performance double disc coulter for the Cataya Super

TwinTeC-Schar (1)

Precise high-performance at up to 60 kg coulter pressure
Equipped with the high-performance TwinTeC coulter, the seed drill offers a precise and robust double disc coulter. With a disc diameter of 340 mm, the coulter provides very precise and tidy seed placement at a coulter pressure of 60 kg, even at higher speeds and on inconsistent soils. Thanks to the parallelogram guidance of the coulter, the coulter pressure and the placement depth can be adjusted independently, so that optimum seed placement is ensured. The coulter impresses with its smooth running, even under the most difficult of conditions.

Advantages of the TwinTeC double disc coulter 

  • Its highest levels of flexibility permit central independent adjustment of the placement depth and the coulter pressure 
  • High-precision seed placement as a result of its very smooth and tidy running 
  • Consistent sowing depth with the high, constant coulter pressure of 60 kg 
  • Best ground contour following for the coulter, based on the parallelogram coulter guidance 
  • Simple central working depth adjustment 
  • Reliable blockage-free sowing, even under difficult conditions, as a result of the high throughput ability 
  • Maintenance-free

Central setting of the sowing depth

A depth guidance roller behind each TwinTeC coulter provides precise depth guidance thus ensuring that the placement depth of each individual TwinTeC coulter is maintained. Thanks to the large coulter clearance of 195 mm and the linkage to the depth guidance roller via the top guided roller carrier, sufficient space remains, meaning that blockage-free operation is possible. Due to the low angle of attack of the sowing discs of 10°, excellent material passage is ensured even at high forward speeds and with large amounts of crop residues.

There is a choice of two different depth guidance rollers. The Control 50 mm depth guidance roller has a high through passage and is ideal for heavy ground with good carrying capacity. On the other hand, the Control 65 mm depth guidance roller offers a higher carrying capacity, which is ideal for lighter soil types.

Easy and quick – mechanical coulter pressure adjustment

Roller harrow for the Cataya Super with RoTeC coulters

The roller harrow for the Cataya Super additionally consolidates the soil above the seed furrow, providing the optimum germination conditions. This is recommended especially for light, dry soils when sowing spring crops or rape. An undulating surface profile that reduces erosion is the result. The roller harrow, adjustable separately from the coulter pressure, can follow the ground contours over a range of ± 100 mm.

Harrow tines on the TwinTeC coulter

As an option, every TwinTeC coulter can be equipped with a directly suspended harrow. Due to its profile, a shorter space and less lift capacity is required. Even in undulating ground, depth guidance is carried out without any problem thanks to the suspended harrow bracket.

In addition, every harrow can be adjusted as required. To compensate for wear and tear, the harrow can be readjusted in 7 steps down to a length of 150 mm. In addition, the intensity of the harrow can be set by repositioning a pin in three steps (30°, 45° and 60°).

Due to the close proximity of the harrow, it is possible to sow right up to the field margins.
