Horsch breaks new ground

The Horsch Avatar SD is a new entry into the direct drilling with discs sector. So far there has only been tine seed drills available for this sector.
At Lamma the Avatar SD was launched in 4, 6 and 12m working widths. A coulter pressure of 200kg guarantees good penetration into the soil, while the strong coulter frame eliminates sideways movement and keeps to a set sowing depth on uneven soils.
A press wheel then closes the seed furrow and consolidates the seed row.
The Avatar SD in 4m working width weighs 5,800 kg, in 6m 9,300 kg and in 12m working width 19,160 kg.
Despite the high weight, which is necessary for a direct seed drill, the horsepower requirement of the Avatar SD remains relatively low as the single disc coulters are arranged in two bars. Horsch relies on the well-proven components of its Pronto DC seed drills for hopper and metering.
The hopper size is 1,500 litres for the 4m wide model, 3,500 litres for the 6m version and 12,000 litres for the 12m wide machine.
Each assembly comprises a straight disc to cut through trash, a smaller angled opening disc and seed coulter, and an angled steel press wheel to give targeted consolidation of the slot.
Depth control of the coulters is carried out via the well-proven rubber suspension of the Pronto in a larger and stronger version which is required due to the high coulter pressure.
