Increasing the efficiency of machine usage for transport services in agricultural holdings can be achieved by creating stocks of aggregates and units in company warehouses based on a predetermined gamma-percentage of available resources.
This study proposes a methodical approach to determine the 80% of gamma-percentage resource for forklift elements, considering both known and unknown distribution laws for their resources. It includes truncated and repeatedly truncated samples.
The results obtained from this study can be utilized for planning purposes and establishing stock levels to ensure the operational readiness of Bulgarian forklifts.

On the basis of theoretical and experimental studies with the application of the similarity and dimensional theory and planning of multifactorial experiments typical similarity criteria, criterion equations and regression mathematical models of reduction processes are obtained, verification of their adequacy and optimization by means of a steep ascent method is conducted.
The physico-mechanical properties (adhesion strength, hardness, wear resistance) of the obtained metal coatings are investigated and resource-saving technological processes are developed for recovery of worn-out parts of agricultural machinery via iron-plating, electroplating and electric-spark alloying in order to increase their reliability.

As a result of researches the original compositions of electrolytes, accessories and recovery modes are worked out, the novelty of which is justified by appropriate patents and author’s certificate for invention.
