RoTeC pro-Schar – Das universelle Einscheibenschar (1) RoTec_pro_Exaktstriegel_114_d1_190913

RoTeC coulter – The universal single disc coulter

Reliable and precise 

RoTeC coulters are maintenance-free and work very reliably, even where large amounts of straw and plant residues prevail. The sowing disc and furrow former create the seed furrow profile and provide the 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

  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. Choice of 25 mm or 10 mm “Control” combined depth control and cleaning disc for even seed placement.
  4. Furrow former for a clean profile seed furrow.
  5. Seed guide tube up to the furrow former for an even seed placement.
  6. Exact harrow for excellent seed coverage.
  7. Sowing disc ∅ 320 mm made of boron steel, working angle of 7°, for smooth operation of the coulter.

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 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. Working with less coulter pressure is possible without any problem when sowing rape or early sowing in dry conditions.

The simple alternative for successful sowing

The TwinTeC special coulter for mounted seed drills means that AMAZONE can offer the ideal coulter for light and medium soils at speeds up to 10 km/h. At a coulter pressure of up to 40 kg/coulter, the coulter travels very smoothly through the soil and places the seed precisely and reliably.

Benefits of the TwinTeC special coulter 

  • Reduced lifting force as a result of the lightweight design 
  • Better handling on the road and in the field as a result of its compact design 
  • Good soil-seed contact provided by trailing depth guidance roller 
  • Perfect depth control and simple setting as a result of trailing depth guidance roller 
  • Cost-sensitive alternative to the TwinTeC double disc coulter 
  • Simple operation and straightforward maintenance

Easy manual adjustment

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. The placement depth is easily adjusted on the right and left of the Centaya Special. The placement depth can be infinitely variably adjusted in each case, depending on the position of the depth guidance roller. Infinitely variable

setting ranges: 

  • 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 Centaya Special.

Hydraulic coulter pressure setting with coulter lift

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

Exact harrow for the RoTeC coulter

The Exact harrow tine has a thickness of 10 mm, is low-wearing and provides excellent seed coverage. The Exact harrow serves for both coverage of the open seed furrows and for levelling. It operates without blockage, even where there are large amounts of surface straw. Individual, swivel-mounted harrow elements allow it to adapt to uneven ground and achieve an even seed coverage.4

Exact S following harrow
With its 12 mm tine diameter, the Exact S following harrow offers even more wear area and is therefore resistant to the most arduous of operational conditions.

The harrow pressure is adjusted mechanically by pre-tensioning the harrow springs. When equipped with hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. As a result, the harrow pressure and the coulter pressure can be simultaneously matched to changing soil types via just one tractor spool valve whilst on the move.

Coulter harrow on the TwinTeC special coulter

The TwinTeC special coulter can be equipped with a rear-mounted harrow as an option. The coulter harrow provides additional loose soil on top of the seed furrow.

The benefits: 

  • Depth control with a suspended harrow bracket 
  • Adjustable in seven steps up to 150 mm 
  • The intensity can be adjusted in three steps (30°, 45°, 60°) 
  • Low lifting power requirement as a result of the compact design
