Vibrations are dynamic phenomena occurring in elastic or quasi-elastic media after a local excitation and becoming manifested by propagating the excitation within the medium in the form of some elastic oscillations. Thus, depending on the phenomenon

In this paper was performed a thorough analysis of the effects of the conservative system of mechanized works, minimum-till (hard disc and scarifier) and no till (direct sowing), compared to the classic system (ploughing), highlighting the influences
