Abstract

The paper presents measurements performed during two agrotechnical seasons. Quantities of vibrations which affect the whole body 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 and each taking 30 minutes. Agricultural field where study was performed is owned by the Agricultural High school in Osijek. The device used to measure the vibrations is the MMF 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 whole body 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 from following agrotechnical season (when the same tractor had more than 1000 more working hours), can be concluded 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.
