Harvesting Technology - BM - series | BM 300

6-row, efficient, maintenance friendly

The defoliator type BM 300 is a six-row trailed defoliator equipped with a steel flail shaft and two cleaning shafts. The machine is mainly used in a so-called two-phase harvesting process for beets, chicory roots and celeriac. The leaf is chopped at full width of the machine and deposited Inline between the (beet) rows. Row widths between 45 cm and 50 cm resp. 18" and 20" available for the BM 300.

Clean defoliating

The steel flail shaft and the two counter-rotating cleaning shafts ensure a perfectly defoliated crop. 

Simple and effective:

Low maintenance drive of the shafts, using v-belts on the r/h and l/h-side of the machine.


  • Clean chopped leaves are the basic for a good start into the harvest.
  • Clean removing of weed between the rows
  • Reliable defoliating by use of one steel flail shaft and two counter rotating cleaning shafts with rubber flails.
  • Avoids blockages in the harvester and give clean harvested crop
