Fully hydraulic drive

The fully hydraulic drive allows the speed of all cleaning units to be controlled automatically. All cleaning units can be supplied at maximum power at a PTO speed of 450 rpm. In order to adapt to different harvesting conditions the cleaning elements can be controlled independently from the engine speed over the entire speed range. If full power is not required, the PTO speed and engine speed can be further reduced.

Unique drive concept

  • Many settings can be made directly at the picking table, optionally also at the terminal
  • Fast and convenient adjustment of the machine for variable harvesting conditions, up to 6 lifting programmes can be saved
  • Fully hydraulic drive of the complete harvester, thus extremely low vibration and reduced noise
  • No chains, belts and tensioners, i.e. no adjustment, less wear parts, increased operational reliability
  • Only one articulated shaft, therefore fewer lubrication points
  • Significantly reduced noise level, more comfortable for sorters

  • All cleaning units maintain their optimal speed independently of the PTO speed
  • The leaf chain speed can be reduced by up to 20 % in relation to that of the sieve conveyors

  • Automatic function of sieve conveyors controlled by driving speed for gentle harvesting
  • Soft start of all belts and cleaning units

  • Continuous pressure monitoring with overload warning for the hydraulic system prevents the harvester from overrunning
  • Mechanical slip clutch not necessary – significantly improved power transmission
