The evaluation performance of a harvester should include the energy needed for its operation, the harvesting capacity and the quantitative loss in the process. The objective of this work was to evaluate the performance of a bean harvester. Field tests were done in different operational conditions. Based on the collected data, it was concluded that the harvester header causes the greatest quantitative loss, responsible for 49.30% of the total loss. In the separation and cleaning systems the losses were 43.61 and 7.09%, respectively. The maximum harvesting capacity of the machine was 6.56 t h-1 of grains.
