Contour sowing unit
Smooth running for precise placement
The AMAZONE Contour sowing unit is ideally suited to both mulch sowing and when working after the plough. The outstanding feature of the AMAZONE Contour sowing unit is the low singling disc position with a drop height of only 140 mm. The sophisticated coulter technology creates a seed furrow, virtually free from any organic matter. The sowing coulter undercuts the clearing disc, resulting in a well re-consolidated wedge shaped groove.
These are the optimum pre-conditions but, under very light and sandy soils, the additional carrying wheel can be fitted on to the Contour sowing coulter to prevent it sinking too deeply into the soil. In this way the placement depth can be maintained significantly better.
The Contour sowing unit is guided via a longitudinal tandem, supported at the front by a one-sided press roller and at the rear by a V-press roller or Farmflex tyres. In this way the influence of the ground contours on the smooth ride of the unit is significantly reduced. Clods do not make the unit jump but it smoothly runs over them. So, any change in placement depth due to an uneven soil surface is minimised.
The front press roller has been deliberately mounted just on the one side so that the soil, thrown up by the fertiliser coulter, does not create additional movement on the unit. Thanks to the suspension in the longitudinal tandem, the unit can, on the one hand, optimally match the field contours and on the other hand it maintains a very smooth run at high forward speeds and on rough ground. Both factors result in an optimum accuracy of work with a precise placement depth. The weight distribution on the two press rollers in the longitudinal tandem can be adjusted. Depending on the soil conditions, always the right operating settings can be found.
