Central setting of the sowing depth
A depth guidance roller behind each TwinTeC coulter provides precise depth guidance, thereby ensuring that the placement depth of each individual TwinTeC coulter is maintained. Thanks to the large coulter clearance of 195 mm and the connection to the depth guidance roller via the top guided roller carrier, sufficient space remains so that blockage-free operation is maintained. Due to the sowing discs’ low angle of attack of 10°, a superb passage of material is ensured even at high forward speeds and in copious amounts of crop residues.
There is a choice of two different depth guidance rollers. The Control 50 mm depth guidance roller has a large passage and is suited especially for heavy soils that have a good carrying ability. On the other hand, the Control 65 mm depth guidance roller offers a higher carrying capacity, which is ideal for lighter locations.
