CAN data were logged from agricultural field machinery for various operations to support the characterization of engine load and performance profiles. These load profiles were utilized to generate machinery management data and working/turning/dwell machine times in support of techno-economic modeling of agricultural field machinery systems. Time series and frequency plots were generated for data extracted from SAE J1939 registered CAN messages including engine speed, fuel use rate and engine torque load. Specifically, standard load, engine speed and fuel consumption profiles were created for an anhydrous ammonia applicator during field operation. These profiles were divided into idle, turning and working periods based on the fuel rate and % torque. Regression analyses were performed and R2 values of 0.92 and 0.94 were obtained between fuel use rate and percent torque, and fuel use rate and product of percent engine speed and percent torque, respectively, indicating that fuel use rate profiles can be a good proxy for determining average duty cycles of agricultural field machinery.
