Improvement of machines for the application of mineral fertilisers is an urgent task both in terms of increasing productivity and uniform distribution across the working width. The disc centrifugal apparatus, as a rule, have a vertical axis of rotation. A working hypothesis has been suggested that the inclination of the axis of rotation in this case makes it possible to increase the spreading distance of fertilisers and thereby increase the working width of spreading. For experimental research a special stand was developed that allows to study distribution depending on the inclination of rotation axis of the fertiliser distribution disc, the disc rotation frequency and a number of other parameters. The investigations were carried out using ammonium nitrate. It was found that an increase in the rotational frequency of the disc of the new working body 500…1100 rpm, and the angle of inclination of rotation axis to the horizontal plane 55…95 º leads to a significant displacement of the entire mass of fertilisers from the spreading working body in the direction of their distribution. Better performance of the technological process of the fertiliser application by the range and uniformity of distribution takes place, when the angle of inclination of rotation axis of the disc of the new fertiliser distribution working body in the horizontal plane is within 55…60 º.
