The objectives of this study were to analyze and quantify the influence of slopes (lowland average slope of 7.76°, and hillside average slope of 17.17°) and planting spacings (3m x 2.5m, 3m x 3.33m and 3m x 4.0m) on the productive capacities of the harvester in eucalyptus plantation in the first rotation. The technical and economic analysis is based on time and motion study, crop yields and production costs of the harvester. The results showed that the activity of tracing consumed 46% of the operational cycle, and the harvester' s productivity tended to be greater when the spacing increased, and lower with increasing slope. On average, the spacing 3m x 2.5m and 3m x 3.33m, generated a higher cost of about 11% and 2% higher over the spacing 3m x 4m. Regarding the slope, the details of this negative impact generated by the hillside was 11% when compared to the lowlands.
