Assessment of individual reliability indicators and rational service life of agricultural tractors

Abstract

Nowadays, a case-by case approach to optimizing and rationalizing the machine usage parameters is relevant. One of the ways to improve the efficiency of the machine and tractor fleet operation with regard to individual reliability indicators is to assess the rational tractor service life. According to the proposed model, the tractor is to be decommissioned when it ceases making a profit. Aiming to test the proposed model, ten 3 kN class tractors, operated in agricultural enterprises in the Vologda district of the Vologda region, have been under research for five years. As a result, it has been found out that all the tractors under study have different reliability and, consequently, different rational service life periods.
