Planting technology - Cup planter | GL 420 Exacta

4-row, up to 2 t hopper, in combination with soil cultivation

The GL 420 Exacta is a short, combined and carried potato planter with the proven arrangement of the planting elements. The unique design of the machine of our potato planter Type "GL 420 Exacta" results in the smallest distance between tuber discharge and ridge form plates, which is available on the market. The small distance ensures that even on slopes the tubers do always lie perfectly in the middle of the ridge. Due to the mechanical coupling between the furrow opener and the ridge forming plate an "exact" planting depth is ensured. For the operation with a tractor (from 110 kW / 150 HP) with wide wheels either a rotary harrow or full width tiller is available. The compact design of the machine without running wheels, avoids soil compaction behind the cultivator. The distinctive construction is advantageous in small, odd shaped fields and on slopes.

Simple connection between the tank system in the tractors front and the potato planter at the tractors rear side, using interfaces which are provided for this purpose

Compact and short design

Even filling of the planting elements via feeding belts

Carrying roller to even the ground between the tractor wheels

Benefits

  • The powerful planting element enables a simple adaption to the tuber size and ensures therefore an exact planting distance
  • Planting element arrangement in the proven design.
  • The combination of specially developed furrow opener, planting cups, the longest singling way, an adjustable drop rod and a low drop height enable an even planting distance in the required planting depth.
  • Different setting options of the machine together with good calibrated seed enable a high planting speed.
  • Very short combi potato planter in conjunction with GRIMME Rotary Tiller GR 300 or Lemken Zirkon 12 for soil cultivation
  • The compact design of the machine without running wheels, avoids soil compaction behind the cultivator
  • The furrow openers are directly connected with the shaping board and achieve an even planting depth ensuring good growth
  • Optimum singling of the tubers via automatic planting element filling with sensor operated feed conveyor
  • Less seed potatoes required with the automatic single row deactivation of the planting elements with Section Control and hydraulic single row drive
  • Clever Planting realizes better tuber growth as the planting distance is smaller next to the spraying tracks, as well as using the nutrients and light from the spraying tracks.
  • The GRIMME nozzle system ensures complete dressing of the tuber, and the GRIMME tank system enables a safe handling as well as a proper crop protection
  • Option to applicate micro granular directly into the furrow for an optimum growing start or for seed protection
