The output capacity of the machine for top spreading the soil with solid mineral
fertilisers can be raised by means of increasing its working width. The authors have carried out
field trials and field experiment investigations with the MVU-8 granulated mineral fertilizer
spreading machine equipped with two prototype units of the centrifugal fertiliser spreading tool,
in which the axis can be tilted at different angles to the vertical line. In accordance with the results
of the completed investigations, it has been established that setting the axial tilt angle of the
centrifugal operating device in the fertiliser spreading tool within the range of 25–30° provides
for achieving a productivity of the combined tractor-implement unit for applying mineral
fertilisers at a level of 35–40 ha per working shift hour. The best performance in the fertiliser
application with regard to both the working width and the fertiliser placing distribution uniformity
is ensured at angles of inclination of the disc in the fertiliser spreading tool with respect to the
horizontal plane within the range of 25–30°. At these angles, the uneven distribution of the
fertiliser over the working width is equal to 19.2%, the uneven distribution of the fertiliser along
the unit’s line of travel is equal to 8.9%, while the deviation in the dosage of the applied fertilisers
from the set value is equal to 7.5%.
