AMAZONE moved a huge step forward with the so-called hoop ring rollers on each coulter to the left and right of the seed furrow. These provide individual and reliable control of the depth of each coulter. In addition, the seed furrow is uniformly closed with loose and finely crumbled soil, even in very wet soils or wet patches. And all this even at forward speeds of up to 18 km/h.
That means: no matter how much soil is thrown to the side by the chisel opener, the two round discs deflect most of it back over the seed furrow. The angular adjustment of the discs adds a slight pressure from both sides. What the rollers do not manage to bring back in is finished off by the Exact harrow. This also ensures a level field. The Roller harrow brings up the rear and can consolidate the loose soil above the seed furrow if necessary.
- Good seed/soil contact as a result of the chisel opener clearing the seed furrow.
- A large amount of fine-crumbed soil in the seed furrow which leads to quick warming of the soil in the seed area.
- Perfect germination conditions
The hoop ring consists of Reflex discs and the hoops as supporting elements. The hoops fitted to the outer side of the reflex discs are made of thin material and guide both the chisel opener and the Reflex discs at the desired depth at all times – irrespective of the forward speed! Due to their especially narrow shape no bulldozing is created, even in moist soil – so that the machine can be still be utilised even when the soil is still very wet. And all this without scrapers, which, as everyone knows, tend to carry along a mixture of straw and soil, resulting in a significant braking effect and the relevant wear.
The sowing depth is easily adjusted in groups via crank handles mounted centrally on each coulter module – very simple and quick.
