Optima HD II Sowing Unit

Sowing unit 


Universal sowing unit for mulch and conventional sowing

The Optima HD-II row is the universal sowing unit for all conditions from light to heavy soil or in conventional or mulch conditions. The HD-II row can be combined with all Kverneland frame models. It allows safe operation despite plant residues.


Seeding heart without seals

The patented seeding heart by Kverneland has reduced maintenance costs to a minimum. No friction, no wear, low drive torque, minimum maintenance: The seed disc rotates in the seeding heart together with the vacuum chamber. This seeding drum is connected to the vacuum fan via a hollow shaft. This seed heart principal results in no loss of vacuum, and therefore a low vacuum requirement.

  • Optimal depth control even under extreme conditions, due to the heavy basic weight of the sowing unit with the possibility to add additional pressure (up to 100kg) onto each individual sowing unit via the spring-loaded system.
  • Effective ground contour following, due to the large lateral depth control by open gauge wheels (Ø410mm, width 120mm).
  • Precise seed placement by the small coulter which forms a clean furrow. Light re-compaction and seed covering is done by the intermediate press wheel (as option: heavy stainless steel) and the multi-adjustable V-press wheel – to ensure maximum field emergence.
