Hoop ring rollers on every coulter
AMAZONE moved a huge step forward with the so-called hoop ring rollers on every coulter mounted in pairs on either side of the seed furrow created by the chisel. In this way, every coulter is individually and reliably guided at its preset sowing depth and, in addition, the individual seed furrow is always absolutely closed, again and again, with loose soil, even with very moist soils or wet patches. And all this even at forward speeds of up to 18 km/h. That means: how much or how little soil is thrown to the side by the chisel opener “driving” through the soil – the two round discs deflect this soil again over the seed furrow. In addition a slight pressure from both sides is applied and a slight pressurising by the exact harrow or the roller exact harrow. In this way the seed is properly covered and the surface above the seed grains is maintained a little open – relatively loose and this allows – a quicker soil warming around the seed. This, however, only works properly if the entire seed is delivered to the moist bottom of the furrow. This functions on the chisel openers due to the long-travel, precise seed guidance system located very close behind the chisel opener. The hoop ring roller consists of the Reflex discs with the hoops serving as the supporting elements. It is wear-resistant and is cast from one piece. The hoop rings fitted to the outer side of the reflex discs, which is made from thin material always guide both the chisel opener and also the Reflex discs at the desired depth – irrespective of their 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.
