For each new machine designed operational parameters exist and the realisation of these parameters determines the ability to perform the operations which it is designed for. It was proved both technically and practically that there is an impact of the using time of machines on the level of realisation of the operational parameters. based on a selective the statistic survey, the impact is analysed in the article of the using time of selected agricultural machines and tractors on the residual market price, repair costs, and the trend of annual utilisation. The outcome is a functional dependency of decreased residual market price, the growth of repair costs, and the trend of annual utilisation. The changes are presented by means of the proportions to the designed parameters and the outcomes can be used for the calculation of operational costs of the machines. |
