In this study, parameters which affect tractor energy efficiencies, such as wheel drive types, fuel injection systems, and transmission types were studied. There is much more data which are relating to tractor energy efficiency in OECD Code 2 tractor test reports. While the calculation of the total efficiency, specific fuel consumption, hourly fuel consumption and power data were measured on OECD Code 2 power take-off and drawbar tests. Results have been evaluated according to tractor technical specification separately and the effect of those specifications have been determined. As well as tractor energy efficiency depends on the engine, wheel drive system, soil type and characteristics, tyres, working pressures, tractor weight, compatibility between tractor and equipment and driving efficiency; The effect of the first two parameters was found to be between 60–70%. According to the results, the average total efficiency of 293 tractors was 28.2%. Among these tractors, the average total efficiency of 4WD tractors was the lowest at 27.7%, while the average total efficiency of tractors with CVT and CRD systems was the highest at 30.8%. While the effect of the CRD injection system on the total efficiency in tractors was 9.03%, this rate was 1.99% in the CVT transmission specific to tractors. The effect of both the CRD injection system and the CVT transmission on the total efficiency of the tractors was determined as 11.2%.
