Tractor Lifetime Assessment Analysis

Abstract

In this paper, two different approaches in analyzing the tractor lifetime assessment are presented. The first one is basedon reliability theory and the other one is based on the relevant experience that was implemented in the ASABE standards.In this way, the dependence of tractor reliability and lifetime on working conditions is presented through two modelsverified in the paper. Tractors from two different producers were analyzed. Experimental data were collected during thetractor working engagement at the fields of Agricultural Corporation Belgrade (ACB). Analyzing the obtained data itis possible to find the mismanagement in the tractor usage. Removing them it is possible to extend the period of tractorutilization. In this way the overall organization of tractor-machinery system on a farm can significantly be improved.
