This paper presents the laboratory tests of the two types of mechanism for seed rate adjustment of grassland drills, in the same working conditions. Tests were conducted on an automated installation, which simulates the working speed of the drill, collects, measures and displays seed quantities. The main quality work indices as: the deviation in relation to the average of samples, the unevenness degree of seeds distribution on the grassland drill working width and seeding rate, were determined and compared.
