Evaluating tractor’s capacity and identifying the best working modes are basic and profound phases to fully exploit and make wise and rational combinations of traction vehicles and various agricultural and industrial implements. What goes parallel with this is the question of energy sources. This paper aimed to assess the use of diesel-biogas fuel and assess its traction characteristics. As a result, the characteristic curves of both diesel alone and diesel-biogas tractors show similar characteristics of power, at a speed of , and traction force of 17kN, with the exceptional difference in the quantity of specific fuel consumption that is and for diesel and diesel-biogas fuels respectively. | Assessment of the traction characteristics of a tractor running with Diesel-biogas fuel
