Abstract
U radu su prikazana mjerenja obavljena tijekom dvije agrotehničke sezone. Mjerene su razine vibracija koje utječu na trup rukovatelja prilikom korištenja dva različita poljoprivredna stroja (malčer i raspršivač). Korišten je traktor „Landini Powerfarm DT 100“. Mjerenje je ponovljeno tri puta u trajanju 30 minuta. Istraživanje je obavljeno na poljoprivrednoj površini Poljoprivredne i veterinarske škole Osijek. Mjerenja su obavljena sukladno normama HRN ISO 2631-1 i HRN ISO 2631-4. Prilikom korištenja malčera izmjerena je veća razina vibracija u smjeru osi x i y, dok korištenjem raspršivača veća je u smjeru z osi. Razine vibracija izmjerene iduće godine (traktor je odradio 1000 radnih sati) prilikom korištenja malčera razine vibracija povećane su u smjeru osi y, dok su u smjeru osi x i z smanjene. U drugoj godini rada s raspršivačem izmjerene vibracije u smjeru x i z osi ostale su podjednake, dok se razina vibracija u smjeru osi y smanjila.

Parallel abstract (English)
The paper presents measurements performed during two agrotechnical seasons. Quantities of vibrations which affect the hull of the operator while using two different agricultural machines (mulcher and atomizer) were measured. During the measurements the " Landini Powerfarm 100 " tractor was used. Experiment was repeated three times, each try taking 30 minutes. Agricultural land used in the study is owned by the Agricultural High school in Osijek. The device used to measure the vibrations is the IMF VM30. Measurements were carried out in accordance with the HRN ISO 2631-1 and HRN ISO 2631-4 standards. The conducted research shows that, depending on the axes we observe, vibrations affect the hull of the operator differently. When using the mulcher, the amount of vibrations by the x and y axes is greater. On the other hand, when using the atomizer the amount of vibrations by the z axis is greater. If we compare the amount of vibrations the following agrotechnical season when the same tractor had more than 1000 more working hours, we can conclude that the mean amount of vibrations when using the mulcher is increased by the y axis and reduced by the x and z axes. When using the atomizer the amount of vibrations by x and z axes remains similar and the amount of vibrations by y axis is reduced
