Abstract

The purpose of research is to justification of methods for the determination of indicators to measure the operational efficiency of domestic wheeled tractors with hydromechanical transmission. Objectives of research include analysis of existing assessment indicators of operating effectiveness of the tracked skidders, analysis of  indicators to measure performance for agricultural tractors and industrial purposes, the analysis of design features of wheeled skidders with hydromechanical transmission, as well as analysis of existing theoretical propositions of forest transport machines interaction  with the subject of labor and portage followed by justification of new assessment indicators of their operational efficiency. The connection of the tractive efficiency factor of wheeled skidder with its operating modes. It is proposed to take into account in the overall coefficient of resistance to movement of skidding resistance coefficient to her turn. It is proposed a new evaluating indicator of the effectiveness of exploitation wheeled skidders with hydromechanical transmission, which is a multiplication of tractive efficiency factor of tractor on the load factor of the engine on capacity.
