摘要

The sugarcane harvester plays a fundamental role in determining the quality of the raw material destined for industrial processing; however, its management is complex due to high acquisition and operating expenses. This study aimed to determine the optimal replacement point for sugarcane harvesters by applying established methodologies adapted to agricultural conditions. The analysis was based on principal component analysis, with evaluations focused on cost, production, availability, hours worked, and harvest year for each machine. The results indicated that, for the JD 3520 harvester, the ideal replacement point occurs at the end of year 3 or the beginning of year 4, when operational costs increase sharply and availability drops significantly, rendering the equipment financially unviable in relation to its productivity. In the case of the JD CH570 harvester, replacement should be considered at the end of year 3, as the costs per ton (R$/t) and per hour (R$/h) begin to rise notably, while operational availability also declines. It is concluded that identifying the optimal replacement moment—by balancing operational, maintenance, and financial factors—is essential for strategic decision-making. This enables planned fleet renewal, aligned with market conditions and supported by a robust database, ensuring greater reliability and confidence for stakeholders.
