In this paper we present the technical performances of the precision sowing machines MONOSEM NG and MONOSEM NG PLUS that were tested on the stand and in working conditions. The machines were tried at different working speeds and we monitored in particular the seed distribution evenness reached by distribution devices. We could see that, though mechanic-pneumatic distribution apparatuses have a more complicated structure, they operate well and achieve a sowing precision corresponding to the crop requirements. Data showed that sowing speed should be limited to 8 km/h and that higher speeds leads to a decrease of seed distribution evenness below admitted limits.
