The fuel consumption rates predicted by ASAE Standards D497.4 were found to be 26-53% higher compared to fuel consumption predicted by models developed. The validation for the fuel consumption models for the two implements was acceptable. Consequently, the fuel consumption rate magnitudes could be successfully predicted by the proposed models with good accuracy. It means that this accuracy (P ≤ 0.05) has been in 34-84%. Comparing the developed model with ASAE data, it was determined that the model and the data are in good treatment.
The output of this research is recommended for regions with similar soil texture. Noting that the parameters related to traction have been used in a dimensionless equation, the forecast results should not be tractor-specific. The prediction equations are capable of predicting fuel consumption values for this case study in the range of dimensionless groups contained in Table 3.
