Abstract: The paper demonstrates how different levels of shaft revolutions affect the performance of mono-disk rotary and pendulum fertiliser widely used by Slovenian farmers. Tests have been conducted on mono-disk rotary spreader manufactured by the Italian company AGREX, and on a pendulum spreader manufactured by Slovenian companz CREINA fr5om Kranj. To establish the impact of different revolution levels on the transverse spread-dispersion, spread width and flow of a fertiliser, both types of spreaders have been submitted totesting at different rpm levels of the tractor drive shaft: at 290 rpm, 410 rpm, and 540 rpm. It has been astablished that the spread width on both spreaders statisticaly significant (P>0.05) increases with the increase of the rpm`s. The fertiliyer flow statistically significant (P<0.05) changes onlyon the pendulum spreaders, whereas on rotary spreaders it has been found out that the fertilizer flow does not depend on the rpm`s.
