Simulator training helps provide safe and cost-effective training for operators of modern forestry machines.
The logging machines require high motor skills, constant concentration, and proper planning. Researchers aimed to analyse the learning curves of the trainees in order to determine the period during which most development takes place. In this study, 11 trainees were trained on a John Deere harvester simulator for approximately 15 hours each. In each case, a clear learning curve could be identified, despite high inter- and intra-person variability. Effective time showed a steady decrease during training, with a group minimum at the end of training. Crane tip distance per tree dropped rapidly in the first 3 to 4 hours, followed by a more gradual decrease. Crane control showed a significant increase by the 9th hour of training. Several crane functions used simultaneously increased more rapidly to almost a maximum value already in the 5th hour.
The individual curves for each trainee were highly variable, showing a wide range of values and shapes. In conclusion, most personal development occurs during the first phase of simulator training, which typically takes approximately 9 to 10 h. It is important to consider significant inter-personal variability and tailor the duration of simulator training to individual needs.
