Babassu biodiesel can contribute to the replacement of regular diesel. The hypothesis given was that the use of diesel B S1800 and B S50 and proportions of babassu biodiesel did not alter the performance of agricultural tractors and nor compromise their operation. The objective was to evaluate the power in the drawbar, travel speed, fuel consumption: mass, volume and time specific, as well as the opacity of the exhaust gas. The experiment was conducted at UNESP/FCAV - IPBEN - Machine Testing Unit, at the Rural Engineering Department located in Jaboticabal, SP, Brazil. For the dynamic test, a test tractor was used. It ran three 40 m parcels with a 15 m space between them. At the end of the course, the tractor parked and the opacity of the exhaust gas was measured. When comparing it with the B S1800 and B S50 diesel, the babassu biodiesel showed an 11.1% and 14.3% increase in specific fuel consumption and a reduction of 68.6% and 58% in gas opacity, respectively. Thus, proportions of babassu biodiesel with diesel B S1800 and B S50 do not compromise the operation of tractor engines
