Today a significant part of solid fertilizers are spread by centrifugal spreaders all over the world, and it is general in Hungary as well. Their popularity is due to their multiple usage, simple construction, low maintenance demand, easy operation and low price. The field performance of spinning disc fertilizer spreaders basically depends on two factors: the forward speed and the working width. As there are some technical, operational and energetic limits of increasing the forward speed, my set objective in this study is to make further developments related to these machines' working width. Rising the working width one can lower the damage of the soil, the costs of operation, and at the same time the area of overlapping falling on unit area, and so the unevenness of spreading. Uneven fertilizer distribution will result in yield loss. The main objectives of the examinations presented hereinafter were to explore the relationships between the parameters considered important from the above mentioned point of view.
