Although the origins are varied and losses occur both before and during harvesting, approximately 80% of them occur by mechanisms of action of the harvester cutting platform. It is necessary to know the causes of losses, whether physical or physiological operational. Thus, the objective was to conduct a survey of potential losses and / or environmental factors that affect machinery and effectively and should be prioritized in a management program in order to raise the efficiency of harvesting. From the collected data determined if the potential of critical failures through the method of analysis and failure mode effects, using a questionnaire listed with the selected quality indicators. It was concluded that in the mechanical harvesting of cotton harvested product loss and impurity had insusceptible rates be prioritized goals in the management of the production process. While the grain crop (soybean / corn) moisture grain and grain breaks are still the main causes in the loss of quality of the product, stressing the importance of harvesters in improving the characteristics at harvest in order to minimize qualitative grain losses.
