| Sumario: | Dry bean mechanized harvest is a common practice in large and medium farms. However, many factors have made difficult the use of combines. Mechanized harvest requires special care because many pods are near the ground, causing significant grain losses. It was set up an experiment to evaluate the dry bean harvest by a combine equipped with flexible cutting platform and axial thrasher. The factors studied were: two dry bean cultivars (BRS Valente and Iapar 81), two harvest periods (morning and afternoon), and three operation speeds (3 km h-1, 5 km h-1, and 7 km h-1). Harvest plant height and grain loss were 93 mm and 135 kg ha-1, respectively. This grain loss was higher in the afternoon than in the morning. The combine speed operation affected plant cut height as well as grain loss. The grain damage was affected by combine operation speed and grain moisture. The combine performance, based on grain quality and capacity of work, was dependent on the speed operation, cultivar type, and grain moisture. KEY-WORDS: Grain loss; grain quality; speed operation; harvest period; dry bean cultivars. |
