A seed planted at the correct depth will emerge at the right time and get a competitive edge against both pests and weeds. Knowing this, every part of the Spirit seed coulter is constructed with precision in mind.
Uneven ground
Having each seed coulter mounted on its own arm allows the seed coulters to respond to any irregularities on the field. The working depth is constantly maintained over the entire working width.
Varying soil types
To adapt to varying soil conditions, the coulter pressure can be altered from the cab on the move. The result is a consistent seed depth over the entire field, despite variations in soil types. The wide press wheel has a great ability to stay on top of the field surface, reducing the need to adapt pressure.
Hilly terrain
To ensure an even seed depth in hilly terrain, Spirit is equipped with active seed coulter pressure. The machine immediately registers if it is located on a crest or a trough. If so, automatic valves directly compensate for an increased or decreased pressure. The seed coulter pressure is kept at a constant pre-set value, irrespective of which working angle the seed coulters are in, relative to the rest of the machine.
