Harvesting Technology - FM - series | FM 300

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

The front-mounted 6-row defoliator, type FM 300, is developed for harvesting beets in a 1-phase process. A counter rotating multi shaft and a cleaning shaft which is rotating in driving direction defoliate the crop in a very gentle way. Up to 4 % more mass yield per hectare are possible, compared to the usual procedures with flail topper and scalper. Machine setting to 45 or 50 cm row width.

Very gentle defoliating of the crop

Two flail shafts are fitted to the defoliator and therefore a scalper unit is not required.

The Original - GRIMME FM defoliator

Clean defoliation without a scalping for over 10 years.

Up to 4 % higher mass yield for beets

Since the rubber flails of the FM front mulcher clean the beets all around and also remove withered beet leaf very well in dry stands, less beet leaf get in the clamps than with other defoliation systems.

Easy and fast maintenance

Due to the special design, the rubber flails can be replaced individually.


  • Very gentle defoliating of the crop
  • Clean defoliating without scalping
  • Up to 4 % more mass yield per hectare are possible, compared to the usual procedures with flail topper and scalper.
  • Perfectly harmonized speed settings of the multi shaft and the cleaning shaft to realise a clean defoliating
