This study was done in a eucalypt plantation of the Minas Gerais state forestry company, to technically and economically evaluate a harvester machine in different terrain slopes and forestry yield. The technical analysis involved time and movements to identify the operational cycle elements and their variations due to the terrain slopes and yield. The economical analysis involved determining operational costs. The terrain slope was classified as flat, wavy and rough and the plantation was divided into low, medium and high yield plots. The simple random sampling was used in nine different situations related to slope and yield. The time spent to process each plot and its yield was determined. The data showed that harvester’s yield decreases with the increasing slope, but increases with increasing individual tree volume to certain point and then tends to decrease.Downloads
