Tractor has been a very important piece of machinery in agriculture, and it has been evolving and progressing over the years with improved and increasingly complex functionality. Despite the availability of Organization for Economic Co-operation and Development (OECD) Code 2 tractor testing procedures to evaluate tractor performance, the tests only evaluate individual power outputs from tractor with controlled lab condition. Additionally, current agricultural machinery management data does not accurately predict the power requirements for various in-field operations. Controller Area Network (CAN) has been incorporated into tractor and other machinery with SAE J1939 and ISO 11783 standards, serving as the communication bus for various on-board electronic controller units (ECUs) and contains many machines operation information that can be used for analyzing machine performance. To analyze tractor operation data that is not available from CAN Bus, Sensor CAN Gateway (SCANGate) was developed to connect to external instrumentation for the study of tractor operation performance. Tractor hydraulic instrumentation system was developed in this study to investigate the in-field tractor hydraulic power usage. Custom orifices were designed and fabricated as a cost-effective solution for hydraulic instrumentation. In combination with pressure gauges, hydraulic power usage was computed. Planting operation data collection was used to validate the hydraulic instrumentation system.
