Cilj ovog rada je bio utvrditi razinu buke kod traktora marke Deutz-Fahr različite starosti i broja radnih sati, da li prelazi dopuštenu graničnu vrijednost i međusobno ih usporediti. Razina buke mjerena je pri uhu rukovatelja sa zatvorenim i otvorenim prozorima, kao i vanjska buka traktora u svim stupnjevima prijenosa. Ispitivanja su provedena u skladu s postupkom propisanim međunarodnim normama ISO 5131 i ISO 362, a dobivene vrijednosti su uspoređene u odnosu na dopušteno vrijeme izlaganja buci obzirom na razinu buke prema ISO normama i Zakonu o zaštiti od buke. Mjerenja su pokazala da najmanje buke emitira traktor Agroplus 310 Ecoline koji je ujedno i najnoviji.Given the proven negative effects of excessive noise on human health, as in other branches of the economy and in agriculture are increasingly pay attention to the protection of workers from noise. The aim of this study was to determine the level of noise of tractors Deutz-Fahr different ages and the number of working hours, whether exceeds the threshold value and compare them with each other. The noise level was measured in the ear operator with closed and open windows, as well as external noise of tractors in all gears. Tests were conducted in accordance with the procedure laid down by international standards ISO 5131 and ISO 362, and the values obtained were compared with respect to the allowed time of exposure to noise due to the noise level in accordance with ISO standards and the Law on Noise Protection. Measurements have shown that at least the noise emitted tractor Agroplus 310 Ecoline who is also the newest
