Analysis of vibrations at handles of single axle tractor and power tiller

The paper reports on the vibration level measurement results on the handles of the LABINPROGRES Super special lux one-axle tractor Alter being analysed, the results are compared to the previously measured vibration levels on the handles of the IMT - 505 LS motocultivator. The measured vibration levels are then discussed in the regard to the operator's daily exposure limits recommended By the ISO 5349 and evaluated according to the some other internationally accepted criteria (e.g. Scandinavian ergonomic check list for the forest mechanisation). According to the existing criteria, the daily operation of the Super special lux one-axle tractor should be limited in order to protect the operator.
