Impressive seed placement
The pneumatic seed drill Spirit 600-900S meters out the seed via two distributor heads, thereby enabling the driver to conduct half machine shut off, directly from the driver seat. To ensure an even seed depth also in hilly terrain and at varying soil types, Spirit 600-900S is equipped with an active seed coulter pressure.
- The sensors in the hydraulic system immediately registers if Spirit is located on a crest or a trough. If so, the valves directly compensates for an increased or decreased pressure. Thereby 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. The result is seen in an impressive seed placement and an even emergence over the entire field, says Johan von Mecklenburg, product manager for seed drills at Väderstad.
