The use of biodiesel as a renewable, non-poison and eco-friendly fuel is a significant solution in this area. In this relation, evaluating the performance characteristics of biodiesel has vital importance. In this research, the experiments were performed using 0, 10, 20 and 30% biodiesel mixed with diesel in a sub-scale tank for evaluating the mixture performance in tractor traction. Diesel fuel was used as the basis for comparisons. The experiments were performance in three tillage depths of 20, 25 and 30 cm, and in three forward speeds of 1.8, 3.6 and 5.4 km/h. For drawbar force measurement an octagonal ring drawbar dynamometer and for real speed a radar were used. The tests were performed in the factorial completely randomized design. The different fuel factors effect were measured on tractor performance parameters (real speed, drawbar force, slip, traction power) in a soilbin. Analyses of variances for the experiments showed that the real speed, slip, drawbar power, traction force and their interaction effects were significant at 5% and 1% of probability level. Adding biodiesel for tractor fuel increased the values for drawbar force and drawbar power. <br />  <strong>Abstract</strong> <br />By depletion of fossil fuel resources in the world, the need for the new resources in the various field and among them in agriculture has raised.
