Abstract
The necessity of using the apparatus of mathematical statistics to obtain high reliability of the results of the evaluation of thereliability indicators of agricultural machinery in comparative tests is justified.
Two models of plant protection machines have been tested and the main numerical characteristics of the indicator production till failure of the failure-free feature have been obtained.
The application of the Student’s criterion for proving the statistical significance of the difference in the tested reliability indicator is justified.
