| Abstract: | Now a large number of tractors, especially middle and large scale tractors, are not used in an economical state. These tractors need to bereplaced urgently. Taking the Dongfanghong-75/54 tractors as an instance,the author studied the economical life of the overhaul-repair-system tractors, and advanced a new calculating model. The paper provides a scientific basis for formulating the replacement policy of the tractors. |
