The BAUER Lagoon Mixer in the heart of France

French company Listech has been a dealer of Bauer slurry tech­nol­o­gy and man­u­fac­tur­er of umbil­i­cal systems for many years. Listech showed Growing News how the Bauer Lagoon Mixer is used in a biogas plant.

In Villers-Les-Ormes, a 460-strong com­mu­ni­ty in the depart­ment Indre in central France, we meet Fréder­ic Lagenette, who, as oper­a­tions manager of the Ceres machine com­mu­ni­ty (French: CUMA), manages an area of around 3,000 hectares. Fur­ther­more he is also respon­si­ble for diges­tate man­age­ment of the company Méthavert who oper­ates a biogas plant pro­duc­ing 15,000 cubic meters of diges­tate per year.

We follow the oper­a­tions manager to one of the lagoons where the diges­tate is stored to see their Bauer MTXH‑L mixer in action, bought on the advice of Bauer dealer Listech. The mixer plays an impor­tant role in spread­ing the diges­tate. Because only if the medium is pre­pared accord­ing­ly and the surface crust and the liquid form a homo­ge­neous mass the diges­tate can be spread onto the fields with the umbil­i­cal system without any problems.

Optimal posi­tion

Driven by a tractor, the seven meter long mixer is put into oper­a­tion and slowly lowered into the 5,000 cubic meter lagoon. In com­bi­na­tion with the tractor’s lifting mech­a­nism and a hydraulic upper linkage, the optimal posi­tion of the agi­ta­tor rod in the lagoon can be easily adjust­ed from the driver’s seat. First, the diges­tate is mixed on the surface for a few hours. After that, the mixer is lowered to stir the liquid at the bottom of the lagoon. The Bauer MTXH‑L mixer can be used at a speed of up to 1,000 rpm (in this case however, Listech rec­om­mends 600 to 700 rpm).

To ensure that the entire lagoon is mixed, the mixer is used at dif­fer­ent points. “It is impor­tant to start the mixer 24 hours before the start of spread­ing and to keep it running during this time so that the diges­tate is opti­mal­ly mixed and can be easily spread onto the fields with the umbil­i­cal system,” says Lagenette. After use, the mixer only needs to be washed and greased.

Perfect cutting performance


Designed for an output power of up to 250 HP (180 KW) at 1,000 rev­o­lu­tions per minute at the PTO shaft, the mixer pro­duces a homog­e­nized, easy-to-spread natural fer­til­iz­er. The mixer con­sists of: lifting frame, agi­ta­tor rod, agi­ta­tor head with agi­ta­tor blades and pro­tec­tive bar as well as a stable framework.


  • Easy to use – espe­cial­ly in one-man-operation
  • Minimal power require­ment: The lagoon mixer con­verts very effi­cient­ly drive power into pres­sure thrust.
  • The mixing- and cutting per­for­mance of the Bauer mixing blades has been opti­mized for use in liquids con­tain­ing solid matter or surface scum.
  • The special design of the guard-ring increas­es the cutting per­for­mance of the mixer. It not only pro­tects the razor-sharp mixing blades from damage in narrow pits and during trans­porta­tion, but also serves to prevent accidents.
  • The Lagoon slurry mixer is avail­able in lengths of 7, 8, 9 or 10 metres. The mixing blades with a 20 mm larger diam­e­ter allow them to achieve up to 50 percent higher performance.
