The main objective of this study was to evaluate if a feed-back system, vibration indicators, could help the tractor driver to lower the exposure of whole-body vibrations. In the first step a literature study were carried out and in the next step a field study, where the vibration indicator was evaluated. The tasks carried out were spraying sowing, rolling and manure spreading. The literature study indicated that silimar studies haven’t been performed earlier and that there are very few whole-body vibration measurements made on agricultural tractors. The interviews with the drivers showed that they found the vibration indicator user-friendly, but difficult to adopt.
