Mineral spreader eco-design: method and real application examples.

This paper shows how information enclosed in the 3D spread pattern measurements obtained with the CEMIB test bench can be used to support scientifically spreader improvements. The main aspects to consider during this first step of improvement are described and explained using real examples. The importance of an adapted choice of mean projection distance is shown, as well as the necessary choice of working width ranges for each disc Then specifications are expressed, as robustness evaluation of the transverse curves, since the beginning of the design. Relation with fertiliser characteristics is introduced, as well as the development of a spreading simulator. Results, mainly articulate around the SULKY X Range spreader design, highlight the technical choices made by SULKY, and the performances reached, as well for main field or border applications.
