The present study had the objective to analyze the Operational and Economic Performances of a whole stalk chopper prototype for sugar cane, comparing them with the found values in the bibliography and referring to the manual cut in burned sugar cane and suggest modifications on the machine mechanical project. The analyzed prototype is presented as a substitution option for the hand workers, which are responsible for the sugar cane cut. The methodologies that had been used in this study were proposed by Ripoli (1986) and Molina Jr. (2000). The prototype was the Phoenix CM500i, manufactured by Motocana Ltd. The tests had been carried out in Costa Pinto Sugar Mill, located in Piracicaba county, Sao Paulo State, during the month of July 2000. The following parameters had been determined: Cut Effective Capacity; Manipulation Effectiveness; Losses; Strange Matter Harvested and a Estimated Cost in the Cut Effective Capacity, Operations costs reduced 36,6%. Dealing with the prototype, projections exercises had been made on the basis of the suggested modifications referring to in its mechanical project.
