Abstract.

Nowadays the actual problem is an individual approach to optimization

and rationalization of machine use parameters. As to individual reliability indices, one

of the ways to improve the operation of the machine and tractor park is the choice of

the rational service life of tractors. According to the proposed model, it is reasonable

to take the tractor out of service when it becomes unprofitable. To verify the proposed

model, 10 hauler tractors of 3,0 category, operated in the agricultural enterprises of

the Vologda district, Vologda region were subjected to studying during five years. It is

revealed that all the tractors under study have different reliability and different rational

service life.

Keywords:

tractor, reliability index, operation time, service life, costs, profit,

individual, rational.
