The big advantage is that the mixer can be used with a tractor at up to 1,000 rpm in continuous operation any time after the V-belt has been removed. A precondition is that the device is installed near the ground. A special compensator allows an angle adjustment of 28° in all directions and can be submerged up to 20 metres (up to 100 metres as a special version). Depending on the engine power, the propeller speed is 330 – 400 rpm. The standard shaft length is 3,200 mm. The wall plate, like the Fermix, has reinforced U-profiles for even more stability. The inclination is adjusted using two upper links which are mounted directly on the wall frame. All upper links are vibration-dampened with rubber inserts.

Basic equipment:

  • Wall frame galvanised, angle-adjustable with special compensator
  • Mixer module galvanised, shaft length 3,200 mm with electric motor and drive elements
  • Mixing propeller Ø 500 – Ø 600 (depending on drive) pusher
  • Module shafts in oil bath
