Abstract

The paper presents the results of research conducted in 2010, 2013 and 2015. The study was carried out three years in order to measure the noise produced on agricultural tractors. Measured were noise levels in accordance with the prescribed standard ISO 6395 which refers to the measurement of external noise of the moving tractor and standards ISO 6396 and ISO 5131 relating to the measurement of internal noise at the operator working place of the moving tractor. The study was carried out in the test area Belje d.d. near Mirkovac. Research was carried out on three tractors Fendt model 410 to determine the changes of produced noise level compared to the changes of the tractor operating hours. The results show that none of the tested farm tractors produced higher noise levels than the permitted 90 dB, and it was also established that the tractors from 2016, with an increase in the number of hours broadcast a higher level of external noise. Tractors from 2015 emit higher levels of internal noise, which is not in accordance with the set hypothesis research.
