Rauch develops a pneumatic fertilizer spreader for three-point attachment. Instead of using centrifugal discs, it distributes fertilizer or seeds using its rods. That brings advantages.
The Rauch Agricultural Machinery Factory will bring a pneumatic precision fertilizer spreader for three-point attachment onto the market. The company from Sinzheim in Baden-Württemberg showed a project study of the Aero 32.1 at Agritechnica.
After further development and testing of Prüfständs, in scattered halls and onthe field Rauch plans from autumn 2021 with the production of the first machines. With the Aero GT , Rauch already has a trailed pneumatic spreader on offer.
Rauch Aero: fertilizer spreader restart with new functions
The technology of pneumatic precision fertilizer spreaders is not new. Rauch stopped production of the Aero 13 years ago. The basic principle: Instead of centrifugal discs, the mineral fertilizer flies with air assistance through a rod and trickles precisely onto the target area – similar to a crop protection sprayer. That has advantages.
The fertilizer spreader distributes the fertilizer largely independently of its trickle and flight properties and is also not so strongly influenced by the wind or the slope of the field.
Technical data Rauch Aero pneumatic precision spreaders:
- 1,900 l tank, attachments increase the volume to 3,200 l
- ISOBUS control
- 4 sections
- SectionControl
- oscillating linkage with slope compensation
Precise pneumatic spreading and versatile
With a pneumatic precision spreader it is possible to spread up to the field boundary and to supply the crop with sufficient nutrients up to the edges. According to Rauch, the precision spreader also offers interesting uses in regenerative crop production because catch crop mixtures and undersown crops can be sown in the standing stand.
Part-specific fertilization
The dosing unit is driven hydraulically. This makes it possible for the four sections to distribute different application rates. The spreading of fertilizer according to application maps is therefore possible very precisely.
First aero models from 2021
In the first step, Rauch will build the aero spreaders in working widths of 27 and 30 m. Then smaller widths of 18 m, 21 m and 24 m will follow. Rauch plans a limited production in the end of 2021. Full series production is to start from October 2022, when the smaller working widths will also be available.

What else can MultiRate do?
- Together with the TaskController, the CCI1200-ISOBUS terminal controls the 30 individual cam wheel sets in order to spread over application maps.
- By specifically switching off individual outlet openings, biotopes in the field such as soils, ponds, marginal strips and running waters – even if they are in the middle of the boom area – are protected from fertilizer entry.
- The use of the deactivation of individual cam wheel sets enables precise wedge spreading in very small grids of 1.0 – 1.2 m.
- The good lateral distribution of fertilizer by the pneumatic spreader to the limit can be further optimized by adjusting the spread rate on the outermost outlet manifold and using a border spreading deflector.
