This research is mainly conducted to obtain basic ergonomic data about tractor operator performance and to analyze the mastering process of tractor operation, especially walking types. This paper mainly deals with the analysis of learning curve patterns of beginner operators to assess the necessary expertise level through a comparison with skillful operators.In the results, we noted that there was positive correlation between physiological strain levels and the levels of technical performance. We thought that the high error levels of the beginners in the beginning of their operation experience were strongly affected by the high mental pressure and inefficient task motion, which was expressed by the high level of physiological strain. The physiological strain level decreased as technical error decreased. The analysis results proved that about 24 hours of effective-working time was necessary for beginners to reach the necessary level of performance and psychological stability. In this regard, we define 3 steps of mastering process of the tractor operation in this paper.
