Different setting options of the machine together with good calibrated seed enable a high planting speed. The machine design with large covering discs in front of running wheels enables easy pulling of the machine, pre-shapes the ridge and avoids soil compaction of loose soil by the running wheels.

Benefits

  • The powerful planting element enables a simple adaption to the tuber size and ensures therefore an exact planting distance
  • 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.
  • 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.
  • Operation via ISOBUS from the tractor terminal
  • 4 wheels following the covering discs ensure a good weight distribution, stability and good traction.
  • A combination with a cultivator is possible for an optimum soil preparation.
  • Various hopper options: Tipping hopper flat (2000 kg), fixed hopper (1200 kg) or tipping hopper low (1700 kg)
  • Uniform growing through constant soil covering of the tubers via hydraulic depth control of the furrow opener and automatic shaping board steering
  • Different options for the ridge shaping, shaping board for a loose to firm ridge with a smooth surface or cage rollers for a more fine crumbled ridge structure
  • 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
