Harvesting Technology - ROOTSTER | ROOTSTER 604

6-row, 4 t bunker, trailed overloading harvester

Simple and robust, this is the formula for the development of the trailed beet harvester ROOTSTER with 4 t overloading bunker, which are available as 6-row variant. All machine functions can be conveniently controlled via an operator terminal. All other drives are mechanical and of low-maintenance design. This does make it easier to carry out repairs and reduces the required power (from 136 kW / 185 HP). Use of the ROOTSTER as 1-phase system by using the FT 300 or FM 300 or the 2-phase system by using the BM 300. Machine setting to 45 or 50 cm row width.

Hydraulic articulated drawbar for exact digging depth adjustment for optimum digging results

Hydraulically driven Oppel wheels for all digging conditions

Low maintenance and reliable, mechanical drive, bunker filling elevator and unloading elevator hydraulically driven


  • Digging, cleaning and transferring:
    • efficient and economic alternative for beet harvesting.
    • high operating comfort
  • 2-phase system with centre discharge
    • extraordinary maintenance friendly
    • for 6-row harvesting worldwide
    • large volume 6 m³ buffer bunker for non-stop use
  • especially affordable:
    • all 1- and 2-phase systems can be pulled by existing tractors.
