The constant process of technical and economical evaluation of the systems of timber harvesting is intrinsic to the timber industry because of being a very important phase which spends large financial investment. In this experiment, it was studied the operational yield and operational and production costs of Hypro forest processor. The technical analysis included a study of time and movements by the method of continuous time. The operational yield was determined by volume in cubic meters of processed wood. The economic analysis included the parameters of operational cost, cost of wood processing and energy consumption. Data analysis evidenced that the operational yield per effective work hour was 38 trees and, in debark cubic meters per effective hour of work was 11.68 m³ h-1, with a cost of debark wood processing of US$ 6.85 per cubic meter.
