6-row, front attachment, gentle defoliating of the beet head

The 6-row Inline front mulcher FM has been developed for the 1-phase process in combination with the ROOTSTER 604. A counter rotating multi shaft and cleaning shaft rotating in driving direction very gentle defoliate the beet. The result are beet heads without any leaves and this achieves up to 10 % higher volume yields then with the conventional scalping method. Machine setting to 45 or 50 cm row width.

Gentle defoliating of the beet head via multi and cleaning shaft without scalper unit


  • Very gentle beet defoliating
  • Optimum set speed of the multi and cleaning shaft realise clean defoliating
  • Up to 10 % more material yield per hectare compared to the usual procedures with the flail topper and scalper.
  • non-scalped beet enable better long-term storing
